The following safety and equipment symbols are used in this document. Indicates a hazardous situation which, if not avoided, will result in death or serious injury. Indicates a hazardous situation which, if not avoided, could result in death or serious injury. Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury. Indicates practices not related to personal injury. a) GENERAL CAUTIONS AND WARNINGS The following general safety precautions and warnings apply. Ensure that all connections to the product are correct so as to avoid accidental risk of shock and/or fire, for example such as can arise from high voltage connected to low voltage termi- nals. Follow the requirements of this manual, including adequate wiring size and type, terminal torque settings, voltage, current magnitudes applied, and adequate isolation/clearance in external wiring from high to low voltage circuits. Use the device only for its intended purpose and application. Ensure that all ground paths are uncompromised for safety purposes during device operation and service. Ensure that the control power applied to the device, the AC current, and voltage input match the ratings specified on the relay nameplate. Do not apply current or voltage in excess of the specified limits. Only qualified personnel are to operate the device. Such personnel must be thoroughly familiar with all safety cau- tions and warnings in this manual and with applicable country, regional, utility, and plant safety regulations. Hazardous voltages can exist in the power supply and at the device connection to current transformers, voltage transformers, control, and test circuit terminals. Make sure all sources of such voltages are isolated prior to attempting work on the device. Hazardous voltages can exist when opening the secondary circuits of live current transformers. Make sure that current transformer secondary circuits are shorted out before making or removing any connection to the current transformer (CT) input terminals of the device. For tests with secondary test equipment, ensure that no other sources of voltages or currents are connected to such equipment and that trip and close commands to the circuit breakers or other switching apparatus are iso- lated, unless this is required by the test procedure and is specified by appropriate utility/plant procedure. When the device is used to control primary equipment, such as circuit breakers, isolators, and other switching apparatus, all control circuits from the device to the primary equipment must be isolated while personnel are working on or around this primary equipment to prevent any inadvertent command from this device. Use an external disconnect to isolate the mains voltage supply. Personal safety can be affected if the product is physically modified by the end user.

1-3 1 GETTING STARTED 1.2 UR OVERVIEW 1 1.2UR OVERVIEW 1.2.1 INTRODUCTION TO THE UR The GE Universal Relay (UR) series is a new generation of digital, modular, and multifunction equipment that is easily incorporated into automation systems, at both the station and enterprise levels. 1.2.2 HARDWARE ARCHITECTURE a) UR BASIC DESIGN The UR is a digital-based device containing a central processing unit (CPU) that handles multiple types of input and output signals. The UR device can communicate over a local area network (LAN) with an operator interface, a programming device, or another UR device. Figure 1–2: UR BLOCK DIAGRAM The CPU module contains firmware that provides protection elements in the form of logic algorithms, as well as program- mable logic gates, timers, and latches for control features. Input elements accept a variety of analog or digital signals from the field. The UR isolates and converts these signals into logic signals used by the relay. Output elements convert and isolate the logic signals generated by the relay into digital or analog signals that are used to control field devices. The unit and software are backwards-compatible with UR devices. b) UR SIGNAL TYPES The contact inputs and outputs are digital signals associated with connections to hard-wired contacts. Both ‘wet’ and ‘dry’ contacts are supported. The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equations used to customize the device. Virtual outputs can also serve as virtual inputs to FlexLogic equations. The analog inputs and outputs are signals that are associated with transducers, such as Resistance Temperature Detec- tors (RTDs). The CT and VT inputs are analog current transformer and voltage transformer signals used to monitor AC power lines. The UR-series relays support 1 A and 5 A CTs. The remote inputs and outputs provide a means of sharing digital point state information between remote UR-series devices. The remote outputs interface to the remote inputs of other UR-series devices. Remote outputs are FlexLogic oper- ands inserted into IEC 61850 GSSE and GOOSE messages. ������������ �������������� ��� ����������� ������ �������� ��������� �������������� ��������������� �������������� ��������������� ������������� �������������� ��������� ��������� ����� ������ ����� ������ ������ ����� ������ ������� ������� ������������������� ����������� �������������� ������������ ���������� ��������������� ������������� ������������� ��������������

GE Multilin 1.2 UR OVERVIEW 1 GETTING STARTED 1 The direct inputs and outputs provide a means of sharing digital point states between a number of UR-series intelligent electronic devices (IEDs) over dedicated fiber, RS422, or G.703 interface. No switching equipment is required as the IEDs are connected directly in a ring or redundant (dual) ring configuration. This feature is optimized for speed and intended for pilot-aided schemes, distributed logic applications, or the extension of the input/output capabilities of a single relay chassis. 1.2.3 SOFTWARE ARCHITECTURE Firmware is the software embedded in the relay in functional modules that can be installed in any relay as required. This is achieved with object-oriented design and programming (OOD/OOP) techniques. Object-oriented techniques involve the use of objects and classes. An object is defined as “a logical entity that contains both data and code that manipulates data.” A class is the generalized form of similar objects. By using this approach, one can create a protection class with the protection elements as objects of the class, such as time overcurrent, instantaneous overcurrent, current differential, undervoltage, overvoltage, underfrequency, and distance. These objects represent com- pletely self-contained software modules. The same object-class concept can be used for metering, input/output control, software interface, communications, or any functional entity in the system. Employing OOD/OOP in the software architecture of the L30 achieves the same features as the hardware architecture: modularity, scalability, and flexibility. The application software for any UR-series device (for example, feeder protection, transformer protection, distance protection) is constructed by combining objects from the various functional classes. This results in a common interface across the UR series.

1-15 1 GETTING STARTED 1.3 ENERVISTA UR SETUP SOFTWARE 1 1.3.6 SETTING UP CYBERSENTRY AND CHANGING DEFAULT PASSWORD If and when first using CyberSentry security, use the following procedure for set up. 1. Log in to the relay as Administrator by using the Value keys on the front panel or through EnerVista connected serially (so that no IP address is required). If logging in through EnerVista choose Device authentication. Enter the default password "ChangeMe1#". Note that the "Lock relay" setting needs to be disabled in the Security > Supervisory menu. When this setting is disabled, configuration and firmware upgrade are possible. By default, this setting is dis- abled. 2. Enable the Supervisor role if you have a need for it. 3. Make any required changes in configuration, such as setting a valid IP address for communication over Ethernet. 4. Log out of the Administrator account by choosing None. Next, device or server authentication can be chosen on the login screen, but the choice is available only in EnerVista. Use device authentication to log in using the five pre-configured roles (Administrator, Supervisor, Engineer, Operator, Observer, or Administrator and Supervisor when device authentication is disabled). When using a serial connection, only device authentication is supported. When server authentication is required, characteristics for communication with a RADIUS server must be configured on the UR. This is possible only through the EnerVista software. The RADIUS server itself also must be configured. The appendix called RADIUS Server gives an example of how to setup a simple RADIUS server. Once both the RADIUS server and the parameters for connecting UR to the server have been configured, you can choose server authentication on the login screen of EnerVista. Figure 1–9: LOGIN SCREEN FOR CYBERSENTRY During the commissioning phase, you have the option to bypass the use of passwords. Do so by enabling the BYPASS ACCESS setting under SETTINGS > PRODUCT SETUP > SECURITY > SUPERVISORY. Be sure to disable this bypass setting after commissioning the device. You can change the password for any role either from the front panel or through EnerVista. If using EnerVista, navigate to Settings > Product Setup > Security. Change the Local Administrator Password, for example. It is strongly recommended that the password for the Administrator be changed from the default. Changing the passwords for the other three roles is optional.

When powered up successfully, the Trouble LED is on and the In Service LED off. The relay in the “Not Programmed” state blocks signaling of any output relay. These conditions remain until the relay is explicitly put in the “Programmed” state. Select the menu message SETTINGS  PRODUCT SETUP  INSTALLATION  RELAY SETTINGS 1. To put the relay in the “Programmed” state, press either of the VALUE keys once and then press ENTER. The face- plate Trouble LED turns off and the In Service LED turns on. The settings for the relay can be programmed manually (see Chapter 5) via the faceplate keypad or remotely via the EnerVista UR Setup software (see the EnerVista UR Setup help file). 1.5.5 RELAY PASSWORDS a) PASSWORD SECURITY It is recommended that passwords be set for each security level and assigned to specific personnel. There are two user security access levels, COMMAND and SETTING. 1. COMMAND The COMMAND access level restricts the user from making any settings changes, but allows the user to perform the fol- lowing operations: • Change state of virtual inputs • Clear event records • Clear oscillography records • Operate user-programmable pushbuttons 2. SETTING The SETTING access level allows the user to make any changes to any of the setting values. See the Changing Settings section in Chapter 4 for complete instructions on setting security-level passwords. b) CYBERSENTRY When the CyberSentry option is purchased, advanced security services are available, using either device authentication or server authentication using RADIUS. When this option is purchased, the basic password security is disabled automatically. For more information, see the CyberSentry content in the Security section of the next chapter. 1.5.6 FLEXLOGIC CUSTOMIZATION FlexLogic equation editing is required for setting user-defined logic for customizing the relay operations. See the FlexLogic section in Chapter 5. RELAY SETTINGS: Not Programmed NOTE

1-19 1 GETTING STARTED 1.5 USING THE RELAY 1 1.5.7 COMMISSIONING The L30 requires minimal maintenance after it is commissioned into service. Since the L30 is a microprocessor-based relay, its characteristics do not change over time. As such, no further functional tests are required. Expected service life is 20 years for UR devices manufactured June 2014 or later when applied in a controlled indoors environment and electrical conditions within specification. The L30 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the Relay Self-tests section in chapter 7). However, it is recommended that L30 maintenance be scheduled with other system maintenance. This maintenance can involve in-service, out-of-service, or unscheduled maintenance. In-service maintenance: 1. Visual verification of the analog values integrity, such as voltage and current (in comparison to other devices on the corresponding system). 2. Visual verification of active alarms, relay display messages, and LED indications. 3. LED test. 4. Visual inspection for any damage, corrosion, dust, or loose wires. 5. Event recorder file download with further events analysis. Out-of-service maintenance: 1. Check wiring connections for firmness. 2. Analog values (currents, voltages, RTDs, analog inputs) injection test and metering accuracy verification. Calibrated test equipment is required. 3. Protection elements setting verification (analog values injection or visual verification of setting file entries against relay settings schedule). 4. Contact inputs and outputs verification. This test can be conducted by direct change of state forcing or as part of the system functional testing. 5. Visual inspection for any damage, corrosion, or dust. 6. Event recorder file download with further events analysis. 7. LED Test and pushbutton continuity check. Unscheduled maintenance, such as a disturbance causing system interruption: 1. View the event recorder and oscillography or fault report for correct operation of inputs, outputs, and elements. If it is concluded that the relay or one of its modules is of concern, contact GE Multilin for service.

2-1 2 PRODUCT DESCRIPTION 2.1 INTRODUCTION 2 2 PRODUCT DESCRIPTION 2.1INTRODUCTION 2.1.1 OVERVIEW The L30 Line Current Differential System is a digital current differential relay system with an integral communications chan- nel interface. The L30 is intended to provide complete protection for transmission lines of any voltage level. Both three phase and single phase tripping schemes are available. Models of the L30 are available for application on both two and three terminal lines. The L30 uses per phase differential at 64 kbps transmitting two phaselets per cycle. The current differential scheme is based on innovative patented techniques developed by GE. The L30 algorithms are based on the Fourier transform– phaselet approach and an adaptive statistical restraint. The restraint is similar to a traditional percentage differential scheme, but is adaptive based on relay measurements. When used with a 64 kbps channel, the innovative phaselets approach yields an operating time of 1.0 to 1.5 cycles (typical). The adaptive statistical restraint approach provides both more sensitive and more accurate fault sensing. This allows the L30 to detect relatively higher impedance single line to ground faults that existing systems may not. The basic current differential element operates on current input only. Long lines with significant capacitance can benefit from charging current compensation if terminal voltage measurements are applied to the relay. The voltage input is also used for some protection and monitoring features such as directional ele- ments, fault locator, metering, and distance backup. The L30 is designed to operate over different communications links with various degrees of noise encountered in power systems and communications environments. Since correct operation of the relay is completely dependent on data received from the remote end, special attention must be paid to information validation. The L30 incorporates a high degree of secu- rity by using a 32-bit CRC (cyclic redundancy code) inter-relay communications packet. Several options are available for communication. A faceplate RS232 port can be used to connect to a computer for the pro- gramming of settings and the monitoring of actual values. The RS232 port has a fixed baud rate of 19.2 kbps. The rear RS485 port allows independent access by operating and engineering staff. It can be connected to system computers with baud rates up to 115.2 kbps. All serial ports use the Modbus RTU protocol. The IEC 60870-5-103 protocol is supported on the RS485 interface. IEC 60870-5-103, DNP, and Modbus cannot be enabled simultaneously on this interface. Also only one of the DNP, IEC 60870-5-103, and IEC 60870-5-104 protocols can be enabled at any time on the relay. When the IEC 60870-5-103 protocol is chosen, the RS485 port has a fixed even parity and the baud rate can be either 9.6 kbps or 19.2 kbps. The 100Base-FX or 100Base-T Ethernet interface provides fast, reliable communications in noisy environments. The Ethernet port supports IEC 61850, IEC 61850-90-5, Modbus/TCP, and TFTP protocols, PTP (according to IEEE Std. 1588- 2008 or IEC 61588), and allows access to the relay via any standard web browser (L30 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port. The Ethernet port also supports the Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option. In addition to current differential protection, the relay provides multiple backup protection for phase and ground faults. For overcurrent protection, the time overcurrent curves may be selected from a selection of standard curve shapes or a custom FlexCurve™ for optimum co-ordination. The L30 incorporates charging current compensation for applications on very long transmission lines without loss of sensi- tivity. The line capacitive current is removed from the terminal phasors. For breaker-and-a-half or ring applications, the L30 design provides secure operation during external faults with possible CT saturation. Voltage, current, and power metering is built into the relay as a standard feature. Current parameters are available as total waveform RMS magnitude, or as fundamental frequency only RMS magnitude and angle (phasor). Settings and actual values can be accessed from the front panel or EnerVista software. The following single line diagram illustrates the relay functionality using American National Standards Institute (ANSI) device numbers.

The fea- ture is available in the default offering of the product and only in the EnerVista software. • CyberSentry security — Advanced security options available as a software option. When purchased, the options are automatically enabled, and the default Password security and EnerVista security are disabled. Changing the password, or any other setting, does not take the relay out of service. The relay is taken out of service when a settings file is written to it. a) ENERVISTA SECURITY The EnerVista security management system is a role-based access control (RBAC) system that allows an administrator to manage the privileges of multiple users. This allows for access control of UR devices by multiple personnel within a substa- tion and conforms to the principles of RBAC as defined in ANSI INCITS 359-2004. The EnerVista security management system is disabled by default to allow the administrator direct access to the EnerVista software after installation. It is recom- mended that security be enabled before placing the device in service. Basic password or enhanced CyberSentry security applies, depending on purchase. b) PASSWORD SECURITY Password security is a basic security feature present in the default offering of the product. Two levels of password security are provided: command and setting. The following operations are under command password supervision: • Operating the breakers via faceplate keypad • Changing the state of virtual inputs • Clearing the event records • Clearing the oscillography records • Clearing fault reports • Changing the date and time • Clearing the breaker arcing current • Clearing the data logger • Clearing the user-programmable pushbutton states

2-5 2 PRODUCT DESCRIPTION 2.1 INTRODUCTION 2 The following operations are under setting password supervision: • Changing any setting • Test mode operation The L30 supports password entry from a local or remote connection. Local access is defined as any access to settings or commands via the faceplate interface. This includes both keypad entry and the through the faceplate RS232 port. Remote access is defined as any access to settings or commands via any rear communications port. This includes both Ethernet and RS485 connections. Any changes to the local or remote passwords enables this functionality. When entering a settings or command password via EnerVista or any serial interface, the user must enter the correspond- ing connection password. If the connection is to the back of the L30, the remote password must be used. If the connection is to the RS232 port of the faceplate, the local password applies. Password access events are logged in the Event Recorder. c) CYBERSENTRY SECURITY CyberSentry Embedded Security is a software option that provides advanced security services. When this option is pur- chased, the basic password security is disabled automatically. CyberSentry provides security through the following features: • An Authentication, Authorization, Accounting (AAA) Remote Authentication Dial-In User Service (RADIUS) client that is centrally managed, enables user attribution, provides accounting of all user activities, and uses secure standards- based strong cryptography for authentication and credential protection. • A Role-Based Access Control (RBAC) system that provides a permission model that allows access to UR device oper- ations and configurations based on specific roles and individual user accounts configured on the AAA server (that is, Administrator, Supervisor, Engineer, Operator, Observer). • Security event reporting through the Syslog protocol for supporting Security Information Event Management (SIEM) systems for centralized cybersecurity monitoring. • Strong encryption of all access and configuration network messages between the EnerVista software and UR devices using the Secure Shell (SSH) protocol, the Advanced Encryption Standard (AES), and 128-bit keys in Galois Counter Mode (GCM) as specified in the U.S. National Security Agency Suite B extension for SSH and approved by the National Institute of Standards and Technology (NIST) FIPS-140-2 standards for cryptographic systems. CYBERSENTRY USER ROLES CyberSentry user roles (Administrator, Engineer, Operator, Supervisor, Observer) limit the levels of access to various UR device functions. This means that the EnerVista software allows for access to functionality based on the user’s logged in role. Example: Administrative functions can be segmented away from common operator functions, or engineering type access, all of which are defined by separate roles, as shown in the following figure, so that access of UR devices by multiple per- sonnel within a substation is allowed. Figure 2–2: CYBERSENTRY USER ROLES The table lists the roles that are supported and their corresponding capabilities. ������������ ������������� �������� ���������� �������� ��������

GE Multilin 2.1 INTRODUCTION 2 PRODUCT DESCRIPTION 2 The EnerVista software has a device authentication option on the login screen for accessing the UR device. When the "Device" button is selected, the UR uses its local authentication database and not the RADIUS server to authenticate the user. In this case, it uses its built-in roles (Administrator, Engineer, Supervisor, Observer, Operator, or Administrator and Supervisor when Device Authentication is disabled) as login names and the associated passwords are stored on the UR device. As such, when using the local accounts, access is not user-attributable. In cases where user attributable access is required especially to facilitate auditable processes for compliance reasons, use RADIUS authentication only. When the "Server" Authentication Type option is selected, the UR uses the RADIUS server and not its local authentication database to authenticate the user. No password or security information are displayed in plain text by the EnerVista software or UR device, nor are they ever transmitted without cryptographic protection. CyberSentry Server Authentication The UR has been designed to automatically direct authentication requests based on user names. In this respect, local account names on the UR are considered as reserved, and not used on a RADIUS server. The UR automatically detects whether an authentication request is to be handled remotely or locally. As there are only five local accounts possible on the UR, if the user ID credential does not match one of the five local accounts, the UR automat- ically forwards the request to a RADIUS server when one is provided. If a RADIUS server is provided, but is unreachable over the network, server authentication requests are denied. In this situ- ation, use local UR accounts to gain access to the UR system. 2.1.4 IEC 870-5-103 PROTOCOL IEC 870-5-103 is a companion standard to IEC 870-5 suit of standards for transmission protocols. It defines messages and procedures for interoperability between protection equipment and devices of a control system in a substation for communi- cating on a serial line. The IEC 60870-5-103 is an unbalanced (master-slave) protocol for coded-bit serial communication, exchanging information with a control system. In the context of this protocol, the protection equipment is the slave and the control system is the master. The communication is based on a point to point principle. The master must be able to interpret the IEC 60870-5- 103 communication messages. The UR implementation of IEC 60870-5-103 consists of the following functions: • Report binary inputs • Report analog values (measurands) • Commands • Time synchronization The RS485 port supports IEC 60870-5-103.

2-19 2 PRODUCT DESCRIPTION 2.3 SIGNAL PROCESSING 2 2.3SIGNAL PROCESSING 2.3.1 UR SIGNAL PROCESSING The UR series relays are microprocessor-based protective relays that are designed to measure power system conditions directly via CT and PT inputs and via other sources of information, such as analog inputs, communications inputs and con- tact inputs. The following figure shows the overall signal processing in URs. An analog low pass anti-aliasing filter with a 3 dB corner frequency is set at 2.4 kHz and is used for current and voltage analog filtering as well as signal conditioning. The same filtering is applied for phase, ground currents, phase-to-phase (when applicable), and auxiliary voltages. The 2.4 kHz cut-off frequency applies to both 50 Hz and 60 Hz applications and fixed in the hardware, and thus is not dependent on the system nominal frequency setting. Figure 2–3: UR SIGNAL PROCESSING The UR samples its AC signals at 64 samples per cycle, that is, at 3840 Hz in 60 Hz systems, and 3200 Hz in 50 Hz sys- tems. The sampling rate is dynamically adjusted to the actual system frequency by an accurate and fast frequency tracking system. The A/D converter has the following ranges of AC signals: Voltages: (EQ 2.1) Currents: From CT/VT U I Analog Inputs Analog low- pass filter Analog-to- Digital Converter A Digital band- pass filter DSP module Phasor estimation ½ cycle Fourier 1 cycle Fourier RMS values Fundamen tal freq.

GE Multilin 2.3 SIGNAL PROCESSING 2 PRODUCT DESCRIPTION 2 (EQ 2.2) Current harmonics are estimated based on raw samples with the use of the full-cycle Fourier filter. Harmonics 2nd through 25th are estimated. True RMS value for the current is calculated on a per-phase basis. The true RMS can be used for demand recording or as an input signal to Time Overcurrent function, if the latter is intended for thermal protection. The true RMS is calculated as per the widely accepted definition: (EQ 2.3) RMS values include harmonics, inter-harmonics, DC components, and so on, along with fundamental frequency values. The true RMS value reflects thermal effects of the current and is used for the thermal related monitoring and protection functions. Protection and control functions respond to phasors of the fundamental and/or harmonic frequency components (magni- tudes and angles), with an exception for some functions that have an option for RMS or fundamental measurements, or some function responding to RMS only. This type of response is explained typically in each element's section in the instruc- tion manual. Currents are pre-filtered using a Finite Impulse Response (FIR) digital filter. The filter is designed to reject DC components and low-frequency distortions, without amplifying high-frequency noise. This filter is referred to as a modified MIMIC filter, which provides excellent filtering and overall balance between speed and accuracy of filtering. The filter is cascaded with the full-cycle Fourier filter for the current phasor estimation. Voltages are pre-filtered using a patented Finite Impulse Response (FIR) digital filter. The filter has been optimized to reject voltage transformers specific distortions, such as Capacitive Voltage Transformer (CVT) noise and high-frequency oscilla- tory components. The filter is cascaded with the half-cycle Fourier filter for the voltage phasor estimation. The URs measure power system frequency using the Clarke transformation by estimating the period of the waveform from two consecutive zero-crossings in the same direction (negative-to-positive). Voltage or current samples are pre-filtered using a Finite Impulse Response (FIR) digital filter to remove high frequency noise contained in the signal. The period is used after several security conditions are met, such as true RMS signal must be above 6% nominal for a certain time and others. If these security conditions are not met, the last valid measurement is used for a specific time after which the UR reverts to nominal system frequency. Synchrophasors are calculated using a patented convolution integral algorithm. This algorithm allows use of the same time stamped samples, which are used for protection and taken at the same sampling frequency. This allows URs to use one sampling clock for both protection algorithms and synchrophasors. Synchrophasors on firmware versions 7.23 and up have been tested and certified to meet IEEE C.37.118-2011 and C.37.118.1a-2014 standards for both metering and protection classes with outputs available up to 60 synchrophasors per second for the metering class and 120 synchrophasors per second for the protection class. Synchrophasors measurement are also available via IEC 61850-90-5 protocol. Contact inputs threshold is settable in the firmware with 17, 33, 84, 166 VDC settings available. Inputs are scanned every 0.5 ms and can be conditioned for the critical applications, using debounce time timer, settable from 0.0 ms to 16.0 ms. Contact inputs with auto-burnishing are available as well, when external contacts are exposed to the contamination in a harsh industrial environment. All measured values are available in the UR metering section on the front panel and via communications protocols. Mea- sured analog values and binary signals can be captured in COMTRADE format with sampling rates from 8 to 64 samples per power cycle. Analog values can be captured with Data Logger, allowing much slower rates extended over long period of time. Other advanced UR order code options are available to support IEC 61850 Ed2.0 (including fast GOOSE, MMS server, 61850 services, ICD/CID/IID files, and so on), IEEE 1588 (IEEE C37.238 power profile) based time synchronization, Cyber- Sentry (advanced cyber security), the Parallel Redundancy Protocol (PRP), IEC 60870-5-103, and so on. ± 2 46rated A ( ) ⋅ IRMS t( ) 1 T--- i2 t( ) t d t ( – T ) t  =

2-21 2 PRODUCT DESCRIPTION 2.4 PILOT CHANNEL RELAYING 2 2.4PILOT CHANNEL RELAYING 2.4.1 INTER-RELAY COMMUNICATIONS Dedicated inter-relay communications may operate over 64 kbps digital channels or dedicated fiber optic channels. Avail- able interfaces include: • RS422 at 64 kbps • G.703 at 64 kbps • Dedicated fiber optics at 64 kbps. The fiber optic options include: – 820 nm multi-mode fiber with an LED transmitter – 1300 nm multi-mode fiber with an LED transmitter – 1300 nm single-mode fiber with an ELED transmitter – 1300 nm single-mode fiber with a laser transmitter – 1550 nm single-mode fiber with a laser transmitter – IEEE C37.94 820 nm multi-mode fiber with an LED transmitter All fiber optic options use an ST connector. L30 models are available for use on two or three terminal lines. A two terminal line application requires one bidirectional channel. However, in two terminal line applications, it is also possible to use an L30 relay with two bidirectional channels. The second bidirectional channel will provide a redundant backup channel with automatic switchover if the first channel fails. The L30 current differential relay is designed to function in a peer-to-peer or master-to-master architecture. In the peer-to- peer architecture, all relays in the system are identical and perform identical functions in the current differential scheme. In order for every relay on the line to be a peer, each relay must be able to communicate with all of the other relays. If there is a failure in communications among the relays, the relays revert to a master-to-peer architecture on a three-terminal system, with the master as the relay that has current phasors from all terminals. Using two different operational modes increases the dependability of the current differential scheme on a three-terminal system by reducing reliance on communications. The main difference between a master and a slave L30 is that only a master relay performs the actual current differential calculation, and only a master relay communicates with the relays at all other terminals of the protected line. At least one master L30 relay must have live communications to all other terminals in the current differential scheme; the other L30 relays on that line may operate as slave relays. All master relays in the scheme will be equal, and each will per- form all functions. Each L30 relay in the scheme will determine if it is a master by comparing the number of terminals on the line to the number of active communication channels. The slave terminals only communicate with the master; there is no slave-to-slave communications path. As a result, a slave L30 relay cannot calculate the differential current. When a master L30 relay issues a local trip signal, it also sends a direct transfer trip (DTT) signal to all of the other L30 relays on the protected line. If a slave L30 relay issues a trip from one of its backup functions, it can send a transfer trip signal to its master and other slave relays if such option is designated. Because a slave cannot communicate with all the relays in the differential scheme, the master will then “broadcast” the direct transfer trip (DTT) signal to all other terminals. The slave L30 Relay performs the following functions: • Samples currents and voltages • Removes DC offset from the current via the mimic algorithm • Creates phaselets • Calculates sum of squares data • Transmits current data to all master L30 relays • Performs all local relaying functions • Receives current differential DTT and Direct Input signals from all other L30 relays • Transmits direct output signals to all communicating relays • Sends synchronization information of local clock to all other L30 clocks The master L30 relay performs the following functions:

GE Multilin 2.4 PILOT CHANNEL RELAYING 2 PRODUCT DESCRIPTION 2 • Performs all functions of a slave L30 • Receives current phasor information from all relays • Performs the current differential algorithm • Sends a current differential DTT signal to all L30 relays on the protected line In the peer-to-peer mode, all L30 relays act as masters. Figure 2–4: COMMUNICATIONS PATHS 2.4.2 CHANNEL MONITOR The L30 has logic to detect that the communications channel is deteriorating or has failed completely. This can provide an alarm indication and disable the current differential protection. Note that a failure of the communications from the master to a slave does not prevent the master from performing the current differential algorithm; failure of the communications from a slave to the master will prevent the master from performing the correct current differential logic. Channel propagation delay is being continuously measured and adjusted according to changes in the communications path. Every relay on the protec- tion system can assigned an unique ID to prevent advertent loopbacks at multiplexed channels.

2-23 2 PRODUCT DESCRIPTION 2.4 PILOT CHANNEL RELAYING 2 2.4.3 LOOPBACK TEST This option allows the user to test the relay at one terminal of the line by looping the transmitter output to the receiver input; at the same time, the signal sent to the remote will not change. A local loopback feature is included in the relay to simplify single ended testing. 2.4.4 DIRECT TRANSFER TRIPPING The L30 includes provision for sending and receiving a single-pole direct transfer trip (DTT) signal from current differential protection between the L30 relays at the line terminals using the pilot communications channel. The user may also initiate an additional eight pilot signals with an L30 communications channel to create trip, block, or signaling logic. A FlexLogic operand, an external contact closure, or a signal over the LAN communication channels can be assigned for that logic.

GE Multilin 2.5 SPECIFICATIONS 2 PRODUCT DESCRIPTION 2 The following specifications apply to filter interface modules implemented from January 2012. The following specifications apply to filter interface modules implemented before January 2012. These power budgets are calculated from the manu- facturer’s worst-case transmitter power and worst case receiver sensitivity. The power budgets for the 1300 nm ELED are calcu- lated from the manufacturer's transmitter power and receiver sensitivity at ambient temperature. At extreme temperatures these values deviate based on com- ponent tolerance. On average, the output power decreases as the temperature is increased by a factor 1dB / 5°C.

The small form-factor pluggable ports (SFPs) are pluggable transceivers. Do not use non-validated transceivers or install validated transceivers in the wrong Ethernet slot, else damage can occur. The relay follows a convention with respect to terminal number assignments which are three characters long assigned in order by module slot position, row number, and column letter. Two-slot wide modules take their slot designation from the first slot position (nearest to CPU module) which is indicated by an arrow marker on the terminal block. See the following figure for an example of rear terminal assignments.

GE Multilin 3.2 WIRING 3 HARDWARE 3 3.2.2 DIELECTRIC STRENGTH The dielectric strength of the UR-series module hardware is shown in the following table: Filter networks and transient protection clamps are used in the hardware to prevent damage caused by high peak voltage transients, radio frequency interference (RFI), and electromagnetic interference (EMI). These protective components can be damaged by application of the ANSI/IEEE C37.90 spec- ified test voltage for a period longer than the specified one minute. 3.2.3 CONTROL POWER Control power supplied to the relay must be connected to the matching power supply range of the relay. If voltage is applied to the wrong terminals, damage can occur. The L30 relay, like almost all electronic relays, contains electrolytic capacitors. These capacitors are well-known to deteriorate over time if voltage is not applied periodically. Deterioration can be avoided by powering up the relay at least once a year. The power supply module can be ordered for two possible voltage ranges, and the UR can be ordered with or without a redundant power supply module option. Each range has a dedicated input connection for proper operation. The ranges are as shown below (see the Specifications section of chapter 2 for details): • Low (LO) range: 24 to 48 V (DC only) nominal. • High (HI) range: 125 to 250 V nominal. The power supply module provides power to the relay and supplies power for dry contact input connections. The power supply module provides 48 V DC power for dry contact input connections and a critical failure relay (see the Typical wiring diagram earlier). The critical failure relay is a form-C device that is energized once control power is applied and the relay has successfully booted up with no critical self-test failures. If on-going self-test diagnostic checks detect a critical failure (see the Self-test Errors section in chapter 7) or control power is lost, the relay is de-energize. For high reliability systems, the L30 has a redundant option in which two L30 power supplies are placed in parallel on the bus. If one of the power supplies become faulted, the second power supply assumes the full load of the relay without any interruptions. Each power supply has a green LED on the front of the module to indicate it is functional. The critical fail relay of the module also indicates a faulted power supply.

3-11 3 HARDWARE 3.2 WIRING 3 An LED on the front of the control power module shows the status of the power supply: Figure 3–11: CONTROL POWER CONNECTION 3.2.4 CT AND VT MODULES A CT/VT module can have voltage or current inputs on channels 1 through 4 inclusive, or channels 5 through 8 inclusive. Channels 1 and 5 are intended for connection to phase A, and are labeled as such in the relay. Likewise, channels 2 and 6 are intended for connection to phase B, and channels 3 and 7 are intended for connection to phase C. Channels 4 and 8 are intended for connection to a single-phase source. For voltage inputs, these channel are labelled as auxiliary voltage (VX). For current inputs, these channels are intended for connection to a CT between system neutral and ground, and are labelled as ground current (IG). Verify that the connection made to the relay terminals for nominal current of 1 A or 5 A matches the secondary rating of the connected CTs. Unmatched CTs can result in equipment damage or inade- quate protection. To connect the module, size 12 American Wire Gauge (AWG) is commonly used; the maximum size is 10 AWG. CT/VT modules can be ordered with a standard ground current input that is the same as the phase current input. Each AC current input has an isolating transformer and an automatic shorting mechanism that shorts the input when the module is withdrawn from the chassis. There are no internal ground connections on the current inputs. Current transformers with 1 to 50000 A primaries and 1 A or 5 A secondaries can be used. The above modules have enhanced diagnostics that can automatically detect CT/VT hardware failure and take the relay out of service. CT connections for both ABC and ACB phase rotations are identical as shown in the Typical wiring diagram. The exact placement of a zero-sequence core balance CT to detect ground fault current is shown as follows. Twisted-pair cabling on the zero-sequence CT is recommended.

3-13 3 HARDWARE 3.2 WIRING 3 3.2.5 PROCESS BUS MODULES The L30 can be ordered with a process bus interface module. This module is designed to interface with the GE Multilin HardFiber system, allowing bidirectional IEC 61850 fiber optic communications with up to eight HardFiber merging units, known as Bricks. The HardFiber system has been designed to integrate seamlessly with the existing UR-series applica- tions, including protection functions, FlexLogic, metering, and communications. The IEC 61850 process bus system offers the following benefits: • Reduces labor associated with design, installation, and testing of protection and control applications using the L30 by reducing the number of individual copper terminations • Integrates seamlessly with existing L30 applications, since the IEC 61850 process bus interface module replaces the traditional CT/VT modules • Communicates using open standard IEC 61850 messaging For additional details on the HardFiber system, see GE publication GEK-113658: HardFiber Process Bus System Instruc- tion Manual. 3.2.6 CONTACT INPUTS AND OUTPUTS Every contact input/output module has 24 terminal connections. They are arranged as three terminals per row, with eight rows in total. A given row of three terminals can be used for the outputs of one relay. For example, for form-C relay outputs, the terminals connect to the normally open (NO), normally closed (NC), and common contacts of the relay. For a form-A output, there are options of using current or voltage detection for feature supervision, depending on the module ordered. The terminal configuration for contact inputs is different for the two applications. The contact inputs are grouped with a common return. The input/output modules have two versions of grouping: four inputs per common return and two inputs per common return. When a contact input/output module is ordered, four inputs per com- mon is used. If the inputs must be isolated per row, then two inputs per common return should be selected (4D module). The tables and diagrams on the following pages illustrate the module types (6A, etc.) and contact arrangements that can be ordered for the relay. Since an entire row is used for a single contact output, the name is assigned using the module slot position and row number. However, since there are two contact inputs per row, these names are assigned by module slot position, row number, and column position. Some form-A / solid-state relay outputs include circuits to monitor the DC voltage across the output contact when it is open, and the DC current through the output contact when it is closed. Each of the monitors contains a level detector whose out- put is set to logic “On” when the current in the circuit is above the threshold setting. The voltage monitor is set to “On” when there is a voltage across open contact (the detector allows a current of about 1 to 2.5 mA), and the current monitor is set to “On” when the current flowing through the closed contact exceeds about 80 to 100 mA. The voltage monitor is intended to check the health of the overall trip circuit, and the current monitor can be used to seal-in the output contact until an external contact has interrupted current flow. If enabled, the current monitoring can be used as a seal-in signal to ensure that the form-A contact does not attempt to break the energized inductive coil circuit and weld the output contacts. Block diagrams are shown as follows for form-A and solid-state relay outputs with optional voltage monitor, optional current monitor, and with no monitoring. The actual values shown for contact output 1 are the same for all contact outputs. Form-A contact output with or without a current or voltage monitoring option is not polarity sensitive. The polarity shown in the figure is required for solid-state contact output connection.

GE Multilin 3.2 WIRING 3 HARDWARE 3 Figure 3–14: FORM-A AND SOLID-STATE CONTACT OUTPUTS WITH VOLTAGE AND CURRENT MONITORING The operation of voltage and current monitors is reflected with the corresponding FlexLogic operands (CONT OP # VON, CONT OP # VOFF, and CONT OP # ION) which can be used in protection, control, and alarm logic. The typical application of the voltage monitor is breaker trip circuit integrity monitoring; a typical application of the current monitor is seal-in of the control command. See the Digital Elements section of chapter 5 for an example of how form-A and solid-state relay contacts can be applied for breaker trip circuit integrity monitoring. Consider relay contacts unsafe to touch when the unit is energized. USE OF FORM-A AND SOLID-STATE RELAY OUTPUTS IN HIGH IMPEDANCE CIRCUITS For form-A and solid-state relay output contacts internally equipped with a voltage measuring circuit across the con- tact, the circuit has an impedance that can cause a problem when used in conjunction with external high input impedance monitoring equipment such as modern relay test set trigger circuits. These monitoring circuits may con- tinue to read the form-A contact as being closed after it has closed and subsequently opened, when measured as an impedance. The solution is to use the voltage measuring trigger input of the relay test set, and connect the form-A contact through a voltage-dropping resistor to a DC voltage source. If the 48 V DC output of the power supply is used as a source, a 500 Ω, 10 W resistor is appropriate. In this configuration, the voltage across either the form-A contact or the resistor can be used to monitor the state of the output. Wherever a tilde “~” symbol appears, substitute with the slot position of the module; wherever a number sign “#” appears, substitute the contact number When current monitoring is used to seal-in the form-A and solid-state relay contact outputs, the Flex- Logic operand driving the contact output should be given a reset delay of 10 ms to prevent damage of the output contact (in situations when the element initiating the contact output is bouncing, at val- ues in the region of the pickup value). ���� � ��� ��� ��� � ������������ � � � � � ������������������������ ���������������������� ����������������������� ���� � � ����������������������������������� ���� � � ������������������������ ����������������������� ����������������������� ������������������������������������ ��������������������������������� ���� � ���� ���������������� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� � ������� NOTE NOTE ������

3-19 3 HARDWARE 3.2 WIRING 3 CONTACT INPUTS A dry contact has one side connected to terminal B3b. This is the positive 48 V DC voltage rail supplied by the power sup- ply module. The other side of the dry contact is connected to the required contact input terminal. Each contact input group has its own common (negative) terminal which must be connected to the DC negative terminal (B3a) of the power supply module. When a dry contact closes, a current of 1 to 3 mA flows through the associated circuit. A wet contact has one side connected to the positive terminal of an external DC power supply. The other side of this contact is connected to the required contact input terminal. If a wet contact is used, then the negative side of the external source must be connected to the relay common (negative) terminal of each contact group. The maximum external source voltage for this arrangement is 300 V DC. The voltage threshold at which each group of four contact inputs detects a closed contact input is programmable as 17 V DC for 24 V sources, 33 V DC for 48 V sources, 84 V DC for 110 to 125 V sources, and 166 V DC for 250 V sources. Figure 3–17: DRY AND WET CONTACT INPUT CONNECTIONS Wherever a tilde “~” symbol appears, substitute with the slot position of the module. There is no provision in the relay to detect a DC ground fault on 48 V DC control power external output. We recommend using an external DC supply. GENERAL APPLICATION CONSIDERATIONS Contacts outputs of protective relays, auxiliary contacts from breakers, disconnectors and other devices, are generally con- nected to contacts inputs of protective relays. In some situations, the contact outputs of some protective relays can have high impedance connected across it. When such a contact output is connected across a L30 contact input, it can spuriously operate the L30 input even when the output is open, if there is a substantial distributed capacitance (represented by C1) present in the wiring between the output and the L30 input and the debounce time setting in the L30 relay is low enough. This false assertion of the contact input, when there is inadvertent ground present at the DC positive terminal, can be pre- vented by inserting a resistor across the L30 input. The following figure shows a typical DC circuit, with battery ground detection, of contact input. The contact output has par- allel impedance across it (represented by R1). ������������ ����������� ������� ����� ��������������� ��������������� ��������������� ����� ��������������� ��� ������ ��� ��� ��� ��� ��� ��������������� ��������������� ��������������� ����� ��������������� ��� ������ ��� ��� ��� ��� ��� ������������� ����� ��� ������ ��� ��� ��� ��� ���������������� ��� �������������� ��� ��� ��� ��� ��� ��� ������������������� ���������������������� ��������������������������� ���������������������� ��������������������������� NOTE

GE Multilin 3.2 WIRING 3 HARDWARE 3 Figure 3–18: TYPICAL CONTACT INPUT DC CIRCUIT The presence of the impedance path (R1) across the contact output allows the stray (distributed) capacitance C1 to charge as shown, thus developing a voltage across the contact input enough to momentarily operate the input while the capaci- tance discharges in the presence of DC ground on the positive terminal of the battery. The duration of the discharge depends on the value of the distributed capacitance, the initial voltage of the distributed capacitance, and the input impedance of the contact input. If the duration is greater than the debounce time setting, then the contact input operates. The application example that follows describes how to mitigate this problem by connecting a resistor across the contact input, as shown in the next figure, or by adjusting the debounce time setting to a value greater than the discharge time to prevent spurious operation of the contact input only if the voltage (with output open) across the contact input due to trickle current is less than the threshold voltage. This operation of contact inputs also can be prevented by using the Auto-Burnish contact inputs or contact inputs with active impedance. Figure 3–19: CONTACT INPUT CONNECTED TO A CONTACT OUTPUT WITH RESISTOR (R2) ACROSS THE INPUT

3-21 3 HARDWARE 3.2 WIRING 3 APPLICATION EXAMPLE This example is for illustrative purposes only and the calculations present the worst-case scenario. In practice, the value of debounce time can be lower. Contact input ON state impedance used in the calculation of the discharge period is based on the following table. Debounce time setting = 2 ms Assume a stray capacitance of 0.1 μF. Assume an initial voltage across the stray capacitance "Vinitial" = 19 V (Vthreshold - 65 V), where Vthreshold = 84 V. The initial voltage Vinitial depends on values of impedance of R1 and contact inputs when the contact input is OFF (non-acti- vated state). Therefore, discharge time constant (τ) =50 kΩ *0.1 μF = 5 ms. Discharge period t is calculated from the following equation: Vthreshold = (Vbatt - VInitial) *e^ (-t/τ) 84 = -149 *e^ (t/0.005) (EQ 3.1) T = -0.005 * ln (84/149) = 0.0029 s Therefore, in this example the contact inputs operate. To prevent this operation, the debounce time must be increased to 4 ms (set debounce time as per the following table) or insert a resistor less than or equal to "R" as calculated later. The value of this resistor "R" is calculated as follows: 1. Determine the minimum voltage (V threshold) required to turn on the input. This is determined by direct measurement or referenced in the input specifications. 2. Calculate the resistance necessary to limit the voltage to 1/3 V threshold (when the contact is OFF, the non-activated state) as follows: R = (Vthreshold / 3) / (2 mA) (EQ 3.2) The 2 mA current is used in case the contact input is connected across the GE Form A contact output with voltage monitoring. Otherwise use the amperage of the active circuit connected to the contact input when its contact output is open and the voltage across the contact input is third trigger threshold to calculate the resistor value. 3. When the contact is ON (operate state), the battery voltage appears across the resistor. The wattage rating of the resistor is then: PR = 1.3 * (Vbatt) ^2 / R Watts (EQ 3.3) 4. Applying the following equation to our example: R = 84 V / 3*(1 / 2 mA) = 14 kΩ PR = 1.57 Watts (EQ 3.4) 5. Calculating the voltage across the contact input with the Burden Resistor, Voltage across the contact Input: Table 3–3: DISCHARGE PERIOD BATTERY VOLTAGE (V) INPUT IMPEDANCE (KΩ) 130 50 250 97 Table 3–4: TYPICAL DEBOUNCE TIME SETTING STRAY CAPACITANCE (μF) BATTERY VOLTAGE (V) DEBOUNCE TIME (MS) 0.05 130 2 0.1 130 4 0.2 130 6 0.05 250 3 0.1 250 6 0.2 250 11

GE Multilin 3.2 WIRING 3 HARDWARE 3 Vresistor = 2 mA * 14 Kohm = 28 V Vresistor < contact input threshold (84 V) (EQ 3.5) In conclusion, in this example, the contact input does NOT operate falsely with the Burden Resistor across its input AND when a battery ground is present.

3-23 3 HARDWARE 3.2 WIRING 3 USE OF CONTACT INPUTS WITH AUTO-BURNISHING The contact inputs sense a change of the state of the external device contact based on the measured current. When exter- nal devices are located in a harsh industrial environment (either outdoor or indoor), their contacts can be exposed to vari- ous types of contamination. Normally, there is a thin film of insulating sulfidation, oxidation, or contaminates on the surface of the contacts, sometimes making it difficult or impossible to detect a change of the state. This film must be removed to establish circuit continuity – an impulse of higher than normal current can accomplish this. The contact inputs with auto-burnish create a high current impulse when the threshold is reached to burn off this oxidation layer as a maintenance to the contacts. Afterwards the contact input current is reduced to a steady-state current. The impulse has a 5 second delay after a contact input changes state. Figure 3–20: CURRENT THROUGH CONTACT INPUTS WITH AUTO-BURNISHING Regular contact inputs limit current to less than 3 mA to reduce station battery burden. In contrast, contact inputs with auto- burnishing allow currents up to 50 to 70 mA at the first instance when the change of state was sensed. Then, within 25 to 50 ms, this current is slowly reduced to 3 mA as indicated above. The 50 to 70 mA peak current burns any film on the con- tacts, allowing for proper sensing of state changes. If the external device contact is bouncing, the auto-burnishing starts when external device contact bouncing is over. Another important difference between the auto-burnishing input module and the regular input modules is that only two con- tact inputs have common ground, as opposed to four contact inputs sharing one common ground (refer to the Contact Input and Output Module Wiring diagrams). This is beneficial when connecting contact inputs to separate voltage sources. Con- sequently, the threshold voltage setting is also defined per group of two contact inputs. The auto-burnish feature can be disabled or enabled using the DIP switches found on each daughter card. There is a DIP switch for each contact, for a total of 16 inputs. Figure 3–21: AUTO-BURNISH DIP SWITCHES 842749A1.CDR 50 to 70 mA 3 mA 25 to 50 ms current time CONTACT INPUT 1 AUTO-BURNISH = OFF = OFF CONTACT INPUT 2 AUTO-BURNISH CONTACT INPUT 1 AUTO-BURNISH CONTACT INPUT 2 AUTO-BURNISH = ON = OFF CONTACT INPUT 1 AUTO-BURNISH CONTACT INPUT 2 AUTO-BURNISH = OFF = ON CONTACT INPUT 1 AUTO-BURNISH CONTACT INPUT 2 AUTO-BURNISH = ON = ON 842751A1.CDR

GE Multilin 3.2 WIRING 3 HARDWARE 3 The auto-burnish circuitry has an internal fuse for safety purposes. During regular maintenance, check the auto- burnish functionality using an oscilloscope. USE OF CONTACT INPUTS WITH ACTIVE IMPEDANCE Contact inputs susceptible to parasitic capacitance caused by long cable runs affected by switching surges from external circuits can result in inadvertent activation of contact inputs with the external contact open. In this case, GE recommends using the digital I/O module with active impedance circuit. Active impedance contact input can tolerate external cable capacitance of up to 0.2 µF, without entering the ON state for more than 2 ms. The contact input debounce time can still be set above 2 ms for added security to prevent contact input activations cause by external transient ON states. An active impedance contact input is normally in Low impedance mode during OFF contact state (non-activated condition). During Low impedance state contact input impedance is maintained at 10 K Ohms impedance to allow fast discharge of the stray capacitance of the long cables. When the contact input voltage exceeds the set threshold, active impedance maintains 10 K Ohms impedance value. If voltage starts rapidly decreasing, this indicates that stray capacitance is being discharged through the contact input. If, however, voltage stabilizes above the set threshold, the input impedance is switched to High impedance mode of 100 K Ohms. This value reduces the input current to <3 mA, and contact input switched to the ON state (operated state). The figure shows the active impedance contact input V-I characteristic. Different thresholds with their corresponding char- acteristics are shown by color. The contact input is in the ON (operated) state if the input voltage is to the right of the col- ored threshold band (+/-10% tolerance), and the contact input is in the OFF (non-activated) state when input voltage is to the left of the band. A contact input is in LOW state during non-operated system condition, and actively switches to HIGH state upon detection of input voltage above the settable threshold. NOTE

3-25 3 HARDWARE 3.2 WIRING 3 Figure 3–22: ACTIVE IMPEDANCE CONTACT INPUT V-I CHARACTERISTIC 3.2.7 TRANSDUCER INPUTS AND OUTPUTS Transducer input modules can receive input signals from external DCmA output transducers (DCmA In) or resistance tem- perature detectors (RTDs). Hardware and software are provided to receive signals from these external transducers and convert these signals into a digital format for use as required. Transducer output modules provide DC current outputs in several standard DCmA ranges. Software is provided to config- ure virtually any analog quantity used in the relay to drive the analog outputs. Every transducer input/output module has a total of 24 terminal connections. These connections are arranged as three ter- minals per row with a total of eight rows. A given row can be used for either inputs or outputs, with terminals in column "a" having positive polarity and terminals in column "c" having negative polarity. Since an entire row is used for a single input/ output channel, the name of the channel is assigned using the module slot position and row number. Each module also requires that a connection from an external ground bus be made to terminal 8b. The current outputs require a twisted-pair shielded cable, where the shield is grounded at one end only. The following figure illustrates the trans- ducer module types (5A, 5C, 5D, 5E, and 5F) and channel arrangements that can be ordered for the relay. Wherever a tilde “~” symbol appears, substitute with the slot position of the module. NOTE

GE Multilin 3.2 WIRING 3 HARDWARE 3 3.2.9 CPU COMMUNICATION PORTS a) OVERVIEW In addition to the faceplate RS232 port, the L30 provides a rear RS485 communication port. The CPU modules do not require a surge ground connection. Figure 3–26: CPU MODULE COMMUNICATIONS WIRING b) RS485 PORTS RS485 data transmission and reception are accomplished over a single twisted pair with transmit and receive data alternat- ing over the same two wires. Through the use of the port, continuous monitoring and control from a remote computer, SCADA system, or PLC is possible. To minimize errors from noise, the use of shielded twisted pair wire is recommended. Correct polarity must also be observed. For instance, the relays must be connected with all RS485 “+” terminals connected together, and all RS485 “–” terminals connected together. Though data is transmitted over a two-wire twisted pair, all RS485 devices require a shared reference, or common voltage. This common voltage is implied to be a power supply common. Some systems allow the shield (drain wire) to be used as common wire and to connect directly to the L30 COM terminal (#3); others function cor- rectly only if the common wire is connected to the L30 COM terminal, but insulated from the shield.

3-29 3 HARDWARE 3.2 WIRING 3 To avoid loop currents, ground the shield at only one point. If other system considerations require the shield to be grounded at more than one point, install resistors (typically 100 ohms) between the shield and ground at each grounding point. Each relay needs to be daisy-chained to the next one in the link. A maximum of 32 relays can be connected in this manner with- out exceeding driver capability. For larger systems, additional serial channels must be added. It is also possible to use com- mercially available repeaters to have more than 32 relays on a single channel. Avoid star or stub connections entirely. Lightning strikes and ground surge currents can cause large momentary voltage differences between remote ends of the communication link. For this reason, surge protection devices are internally provided at both communication ports. An iso- lated power supply with an optocoupled data interface also acts to reduce noise coupling. To ensure maximum reliability, all equipment should have similar transient protection devices installed. Terminate both ends of the RS485 circuit with an impedance as shown below. Figure 3–27: RS485 SERIAL CONNECTION c) 100BASE-FX FIBER OPTIC PORTS Ensure that the dust covers are installed when the fiber is not in use.

The IRIG-B code allows time accuracies of up to 100 ns. Using the IRIG-B input, the L30 operates an internal oscillator with 1 µs resolution and accuracy. The IRIG time code formats are serial, pulse width-modulated codes that can be either DC level shifted or amplitude modulated (AM). The GE MultiSync 100 1588 GPS Clock as well as third-party equipment are available for generating the IRIG-B signal; this equipment can use a global positioning system (GPS) satellite system to obtain the time reference so that devices at different geographic locations can be synchronized. Figure 3–28: OPTIONS FOR THE IRIG-B CONNECTION Using an amplitude modulated receiver causes errors up to 1 ms in event time-stamping. The L30 is intended for use with external clocks that set the IRIG-B control bits according to IEEE Std C37.118.1- 2011. When used with a source that sets the IRIG-B control bits according to IEEE Std 1344-1995, the source must have the sign of its local time offset setting reversed, and if daylight savings time (DST) is used, the source's DST start and DST stop date settings must be interchanged. When IRIG-B is used as the time synchronization source for synchrophasors, the DC level shifted option must be used in order to achieve the 1% Total Vector Error specified by the standard. If amplitude modulated IRIG-B is used, it results in a 20 to 25 degree error in the synchrophasor angle measurement. The IEEE 1588 Precision Time Protocol can also be used to achieve accurate time synchronization for synchrophasor calculation. ���������������� �������� �������� ��������������������� �������������������� �������������� ���������� �� � ������������ ������ ������������������� ������������ ������������������� ������������������� �� ���������� ���������������� �������� �������� ������������������ �������������������� �������������� ���������� �� � ������ ������������������� ������������ ������������������� ������������������� �� ���������� NOTE NOTE

This module is plugged into slot “W” in horizontally mounted units and slot “R” in vertically mounted units. Inter-relay channel communications is not the same as 10/100Base- F interface communications (available as an option with the CPU module). Channel communication is used for sharing data among relays. The inter-relay communications modules are available with several interfaces and some are outlined here in more detail. Those that apply depend on options purchased. The options are outlined in the Inter-Relay Communications section of the Order Code tables in Chapter 2. All of the fiber modules use ST type connectors. For two-terminal applications, each L30 relay requires at least one com- munications channel. The current differential function must be “Enabled” for the communications module to properly operate. Refer to SETTINGS  GROUPED ELEMENTS  LINE DIFFERENTIAL  CURRENT DIFFERENTIAL menu. The fiber optic modules (7A to 7W) are designed for back-to-back connections of UR-series relays only. For con- nections to higher-order systems, use the 72 to 77 modules or the 2A and 2B modules. Observing any fiber transmitter output can injure the eye. 3.3.2 FIBER: LED AND ELED TRANSMITTERS The following figure shows the configuration for the 7A, 7B, 7C, 7H, 7I, and 7J fiber-only modules.

3-33 3 HARDWARE 3.3 PILOT CHANNEL COMMUNICATIONS 3 3.3.4 G.703 INTERFACE a) DESCRIPTION The following figure shows the 64K ITU G.703 co-directional interface configuration. The G.703 module is fixed at 64 kbps. The SETTINGS > PRODUCT SETUP > DIRECT I/O > DIRECT I/O DATA RATE setting is not applicable to this module. AWG 24 twisted shielded pair is recommended for external connections, with the shield grounded only at one end. Con- necting the shield to pin X1a or X6a grounds the shield since these pins are internally connected to ground. Thus, if pin X1a or X6a is used to ground the shield at one end, do not ground the shield at the other end. This interface module is protected by surge suppression devices. Figure 3–32: G.703 INTERFACE CONFIGURATION The following figure shows the typical pin interconnection between two G.703 interfaces. For the actual physical arrange- ment of these pins, see the Rear Terminal Layout section earlier in this chapter. All pin interconnections are to be main- tained for a connection to a multiplexer. Figure 3–33: TYPICAL PIN INTERCONNECTION BETWEEN TWO G.703 INTERFACES Pin nomenclature can differ from one manufacturer to another. Therefore, it is not uncommon to see pinouts num- bered TxA, TxB, RxA and RxB. In such cases, it can be assumed that “A” is equivalent to “+” and “B” is equivalent to “–”. b) G.703 SELECTION SWITCH PROCEDURES 1. With the power to the relay off, remove the G.703 module (7R or 7S) as follows. Record the original location of the module to help ensure that the same or replacement module is inserted into the correct slot. 2. Simultaneously pull the ejector/inserter clips located at the top and at the bottom of each module in order to release the module for removal. 3. Remove the module cover screw. 4. Remove the top cover by sliding it towards the rear and then lift it upwards. 5. Set the timing selection switches (channel 1, channel 2) to the desired timing modes.

Take care to ensure that the correct module type is inserted into the correct slot position. The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously. When the clips have locked into position, the module is fully inserted. Figure 3–34: G.703 TIMING SELECTION SWITCH SETTING c) G.703 OCTET TIMING If octet timing is enabled (ON), this 8 kHz signal is asserted during the violation of bit 8 (LSB) necessary for connecting to higher order systems. When L30s are connected back-to-back, octet timing is disabled (OFF). d) G.703 TIMING MODES There are two timing modes for the G.703 module: internal timing mode and loop timing mode (default). • Internal Timing Mode: The system clock is generated internally. Therefore, the G.703 timing selection should be in the internal timing mode for back-to-back (UR-to-UR) connections. For back-to-back connections, set for octet timing (S1 = OFF) and timing mode to internal timing (S5 = ON and S6 = OFF). • Loop Timing Mode: The system clock is derived from the received line signal. Therefore, the G.703 timing selection should be in loop timing mode for connections to higher order systems. For connection to a higher order system (UR- Table 3–5: G.703 TIMING SELECTIONS SWITCHES FUNCTION S1 OFF → octet timing disabled ON → octet timing 8 kHz S5 and S6 S5 = OFF and S6 = OFF → loop timing mode S5 = ON and S6 = OFF → internal timing mode S5 = OFF and S6 = ON → minimum remote loopback mode S5 = ON and S6 = ON → dual loopback mode ����������� ��������� ������������ ��������������������� ��������������������� ���������������� �������� ��������� ��������� ����� ���� ������������
