General ▪ Ensure that only authorized personnel have access to the device. ▪ Only use the device within an ESP (electronic security perimeter). Do not connect the device to the Internet in an unprotected state. Use mecha- nisms for vertical and horizontal network segmenting and security gate- ways (firewalls) at the transition points. ▪ Ensure that the device is only operated by trained personnel who are fa- miliar with IT security. Commissioning Observe the following recommendations for device commissioning: ▪ User IDs must be unique and assignable. Do not use a "Group account" function or the "Auto login" function. ▪ Activate the "Auto logout" function. ▪ Restrict the rights of the individual user groups as much as is feasible; this helps avoid errors during operations. A user with the "Operator" role, for example, should only perform operations and should not be able to change any device settings. ▪ Delete or disable the default "admin" user ID. This requires first creating a new user account with the "Administrator" role. You can then use it to delete or disable the default "admin" account. ▪ Deactivate service user access. ▪ Enable SSL/TLS encryption; access to the device is then only possible us- ing the SSL/TLS protocol. In addition to encrypting communication, this protocol also checks the authenticity of the server. ▪ Use TLS version 1.2 or higher wherever possible. ▪ Integrate the device into a public key infrastructure. Create your own SSL certificates for this if necessary and then import them. ▪ Connect the device to a central log server by using the syslog interface [►Section 8.7.4, Page 100]. Operation Observe the following recommendations during device operation: ▪ Change the password at regular intervals. ▪ Export the security log at regular intervals. ▪ Check the log files regularly for unauthorized system access and other se- curity-related events.

As an alternative to recording the OLTC oil tempera- ture, the top-oil temperature can be used. 4.3 Function description The product is a monitoring system for monitoring vibro-acoustic signals from on-load tap-changers. You can use the product to detect time and am- plitude anomalies in the vibro-acoustic signal progression and receive event messages when anomalies are detected. The on-load tap-changer is equipped with measuring equipment that records the vibro-acoustic signal in the system throughout the entire tap change se- quence and analyses it immediately upon completion. In addition, the sys- tem determines the changed tap position and the oil temperature in the on- load tap-changer.

Maschinenfabrik Reinhausen GmbH 2021 22 6796573/02 EN MSENSE® VAM Using the implemented algorithms, the monitoring system can reliably detect any potential anomalies that occur in the vibro-acoustic signal progression, taking the temperature variations of the on-load tap-changer oil into account. Status message The MSENSE® VAM monitoring system produces a 3-stage status mes- sage: Status Device/visualization dis- play SCADA/digital output re- mote signaling Normal OK message through blue status message No remote signaling Warning The first and the second anomalies in an evaluation cluster are indicated via a yellow status message in the VAM analysis (Infor- mation menu). No remote signaling Alarm A third anomaly arising in an evaluation cluster or the third successive anom- aly triggers an additional event message (Events menu). This event message is transmitted to a connected SCADA system. In addition, it can also be sent to a digital output. 4.4 Performance features The MSENSE® VAM monitoring system monitors the vibro-acoustic signals from on-load tap-changers and has the following : ▪ Monitoring on-load tap-changers/reactors in accordance with the technical specification in the order confirmation ▪ Suitable for on-load tap-changers with oil-switch and vacuum-switch tech- nology ▪ Recording of the vibro-acoustic signals during on-load tap-changer opera- tion via automatic triggering ▪ Evaluation of the vibro-acoustic signal progression with regard to time and amplitude anomalies ▪ Self-learning limit value at an oil temperature above 15 °C, which moves towards the signal progression with increasing tap-change frequency Ap- proximately 5 tap-change operations per evaluation cluster (e.g. 5x from step 1 to step 2 in reverse tap-change operation) are necessary before the first limit value curve is displayed. The signals are also evaluated below 15 °C, but the limit value is not ad- justed. ▪ Display and recording of the measured and calculated values ▪ Status messages via digital outputs ▪ Web-based visualization

Maschinenfabrik Reinhausen GmbH 2021 38 6796573/02 EN MSENSE® VAM 5 Packaging, transport and storage 5.1 Packaging The products are sometimes supplied with sealed packaging and sometimes in a dry state, depending on requirements. Sealed packaging surrounds the packaged goods with plastic foil on all sides. Products that have also been dried are identified by a yellow label on the sealed packaging. In the dry state, delivery is also possible in a transport container. The information in the following sections should be applied as appropriate. 5.1.1 Suitability NOTICE Property damage due to incorrectly stacked crates! Stacking the crates incorrectly can lead to damage to the packaged goods. ►The outer marking on the packaging states if, for example, the on-load tap-changer or selector has been packed upright. Never stack these crates. ►General rule: Do not stack crates above a height of 1.5 m. ►For other crates: Only stack up to 2 equally sized crates on top of one an- other. The packaging is suitable to ensure undamaged and fully functional means of transportation in compliance with local transportation laws and regula- tions. The packaged goods are packed in a sturdy crate. This crate ensures that, when in the intended transportation position, the packaged goods are stabi- lized to prevent impermissible changes in position, and that none of the parts touch the loading surface of the means of transport or touch the ground after unloading. Sealed packaging surrounds the packaged goods with plastic foil on all sides. The packaged goods are protected from humidity using a desiccant. The plastic foil was bonded after the desiccant is added.

Maschinenfabrik Reinhausen GmbH 2021 39 6796573/02 EN MSENSE® VAM 5.1.2 Markings The packaging bears a signature with instructions for safe transport and cor- rect storage. The following symbols apply to the shipment of non-hazardous goods. Adherence to these symbols is mandatory. Protect against moisture Top Fragile Attach lifting gear here Center of mass Table 10: Shipping pictograms 5.2 Transportation, receipt and handling of shipments WARNING Danger of death or severe injury! Danger of death or serious injuries due to tipping or falling load. ►Only transport the crate when closed. ►Do not remove the securing material used in the crate during transport. ►If the product is delivered on a pallet, secure it sufficiently. ►Only trained and authorized persons may select the sling gear and se- cure the load. ►Do not walk under the suspended load. ►Use means of transport and lifting gear with a sufficient carrying capacity in accordance with the weight stated on the delivery slip. In addition to oscillation stress, jolts must also be expected during trans- portation. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product. If a crate tips over, falls from a certain height (e.g. when slings tear) or is subject to an unbroken fall, damage must be expected regardless of the weight. Every delivered shipment must be checked for the following by the recipient before acceptance (acknowledgment of receipt): ▪ Completeness based on the delivery slip ▪ External damage of any type The checks must take place after unloading when the crate or transport con- tainer can be accessed from all sides.

Maschinenfabrik Reinhausen GmbH 2021 40 6796573/02 EN MSENSE® VAM Visible damage If external transport damage is found upon receipt of the shipment, proceed as follows: ▪ Immediately record the identified transport damage in the shipping docu- ments and have this countersigned by the carrier. ▪ In the event of severe damage, total loss or high damage costs, immedi- ately notify the manufacturer and the relevant insurance company. ▪ After identifying damage, do not modify the condition of the shipment fur- ther and retain the packaging material until an inspection decision has been made by the transport company or the insurance company. ▪ Record the details of the damage immediately on site together with the carrier involved. This is essential for any claim for damages. ▪ Photograph damage to packaging and packaged goods. This also applies to signs of corrosion on the packaged goods due to moisture inside the packaging (rain, snow, condensation). ▪ NOTICE! Damage to packaged goods due to damaged sealed packag- ing. If the product is delivered in sealed packaging, check the sealed packaging immediately. If the sealed packaging is damaged, do not under any circumstances install or commission the packaged goods. Either re- dry the dried packaged goods as per the operating instructions, or contact the manufacturer to agree on how to proceed. ▪ Identify the damaged parts. Hidden damage When damages are not determined until unpacking after receipt of the ship- ment (hidden damage), proceed as follows: ▪ Make the party responsible for the damage liable as soon as possible by telephone and in writing, and prepare a damage report. ▪ Observe the time periods applicable to such actions in the respective country. Inquire about these in good time. With hidden damage, it is very hard to make the transportation company (or other responsible party) liable. Any insurance claims for such damages can only be successful if relevant provisions are expressly included in the insur- ance terms and conditions. 5.3 Storage of shipments Packaged goods dried by Maschinenfabrik Reinhausen Upon receipt of the shipment, immediately remove the packaged goods dried by Maschinenfabrik Reinhausen from the sealed packaging and store air-tight in dry insulating fluid until used if the packaged goods were not sup- plied in insulating fluid. Non-dried packaged goods Non-dried packaged goods but with a functional sealed packaging can be stored outdoors when the following conditions are complied with.

Maschinenfabrik Reinhausen GmbH 2021 41 6796573/02 EN MSENSE® VAM When selecting and setting up the storage location, ensure the following: ▪ Protect stored goods against moisture (flooding, water from melting snow and ice), dirt, pests such as rats, mice, termites and so on, and against unauthorized access. ▪ Store the crates on timber beams and planks as a protection against ris- ing damp and for better ventilation. ▪ Ensure sufficient carrying capacity of the ground. ▪ Keep entrance paths free. ▪ Check stored goods at regular intervals. Also take appropriate action after storms, heavy rain or snow and so on. Protect the packaging foil from direct sunlight so that it does not disintegrate under the influence of UV rays, which would cause the packaging to lose its sealing function. If the product is installed more than 6 months after delivery, suitable mea- sures must be taken without delay. The following measures can be used: ▪ Correctly regenerate the drying agent and restore the sealed packaging. ▪ Unpack the packed goods and store in a suitable storage space (well ven- tilated, as dust-free as possible, humidity < 50% where possible). 5.4 Unpacking shipments and checking for transportation damages ▪ NOTICE! Transport the packaged crate to the place where the packaged goods are to be installed. Do not open the sealed packaging until just be- fore installation. Otherwise, damage to the packaged goods may occur due to ineffectively sealed packaging. ▪  WARNING! When unpacking, check the condition of the packaged goods. Place the packaged goods in an upright crate and protect it from tipping out. Otherwise, the packaged goods may become damaged and serious injuries may result. ▪ Check the completeness of the accessories kit using the delivery slip. Attachment points for lifting gear WARNING Danger of death and damage to property! Danger of death and damage to property due to tipping or falling load! ►Only trained and authorized persons may select the sling gear and se- cure the load. ►Do not walk under the suspended load. ►Use means of transport and lifting gear with a sufficient carrying capacity in accordance with the weight stated in the Technical data [►Section 13, Page 161] section.

The following points must be noted in order to maintain the EMC standards. 6.3.4.1 Wiring requirement of installation site Note the following when selecting the installation site: ▪ The system's overvoltage protection must be effective. ▪ The system's ground connection must comply with all technical regula- tions. ▪ Separate system parts must be joined by a potential equalization. ▪ The device and its wiring must be at least 10 m away from circuit-break- ers, load disconnectors and busbars. 6.3.4.2 Wiring requirement of operating site Note the following when wiring the operating site: ▪ Route the connecting leads in grounded metal cable ducts. ▪ Do not route lines which cause interference (e.g. power lines) and lines susceptible to interference (e.g. signal lines) in the same cable duct. ▪ Maintain a distance of more than 100 mm between lines which cause in- terference and those which are susceptible to interference.

58 6796573/02 EN MSENSE® VAM Figure 38: Recommended wiring 1 Cable duct for lines causing inter- ference 3 Cable duct for lines susceptible to interference 2 Line causing interference (e.g. power line) 4 Line susceptible to interference (e.g. signal line) ▪ Short-circuit and ground reserve lines. ▪ Never connect the device with a multi-wire collective pipe. ▪ For signal transmission, use shielded lines with individual conductors (out- going conductor / return conductor) twisted in pairs. ▪ Connect full surface of shielding (360º) to device or to a nearby grounding bar. Using single conductors may limit the effectiveness of the shielding. Con- nect close-fitting shielding to cover all areas.

59 6796573/02 EN MSENSE® VAM Figure 39: Recommended connection of the shielding 1 Connection of the shielding via a single conductor 2 Full-surface connection of the shielding 6.3.4.3 Wiring requirement in control cabinet Note the following when wiring the control cabinet: ▪ The control cabinet where the device will be installed must be prepared in accordance with EMC requirements: – Functional division of control cabinet (physical separation) – Constant potential equalization (all metal parts are joined) – Line routing in accordance with EMC requirements (separation of lines which cause interference and those susceptible to interference) – Optimum shielding (metal housing) – Overvoltage protection (lightning protection) – Collective grounding (main grounding rail) – Cable bushings in accordance with EMC requirements – Any contactor coils present must be interconnected ▪ The device's connection cables must be laid in close contact with the grounded metal housing or in metallic cable ducts with a ground connec- tion. ▪ Signal lines and power lines/switching lines must be laid in separate cable ducts.

60 6796573/02 EN MSENSE® VAM 6.3.4.4 Information about screening the cables for analog signals In order to correctly record the analog signals, you must place the cable screening in the motor-drive unit on the grounding bar. The cable shielding should be removed as late as possible before connecting to keep the section with unshielded cables as short as possible. The shielding must be con- nected with shielding clips. Figure 40: Examples of supporting screening on ground bar (on left: Direct connection to AIO assembly, on right: Connection using line-up terminal) 6.3.5 Information about laying fiber-optic cable To ensure the smooth transfer of data via the fiber-optic cable, you must en- sure that mechanical loads are avoided when laying the fiber-optic cable and later on during operation. Also observe the information from the manufac- turer of the fiber-optic cable and the following instructions: ▪ Radii must not fall below the minimum permissible bend radii (do not bend fiber-optic cable). ▪ The fiber-optic cables must not be over-stretched or crushed. Observe the permissible load values. ▪ The fiber-optic cables must not be twisted. ▪ Be aware of sharp edges because they can damage the fiber-optic cable's coating during laying or can place mechanical loads on the coating later on. ▪ Provide a sufficient cable reserve near distributor cabinets. Lay the re- serve such that the fiber-optic cable is neither bent nor twisted when tight- ened.

61 6796573/02 EN MSENSE® VAM 6.3.6 Connecting the vibration sensor to the control cabinet Depending on the application, one or more vibration sensors are included in the scope of delivery. Repeat the following steps for a multi-column applica- tion. You must connect the vibration sensor to the control cabinet using the sen- sor cable provided. Note the following information when routing the sensor cable: ▪ Route the sensor cable with as much shielding as possible on the trans- former (e.g. in the tube or cable duct) and along a conductive grounded surface that runs without interruption. ▪ Route sensor cables separately from supply lines and do not create any unnecessary loops. ▪ The vibration sensor cable can also be routed together with the tempera- ture sensor cable in a protective tube. ▪ On the control cabinet, it is advantageous to have routing parallel to the earthing cable that connects the transformer and the control cabinet to- gether. To route the sensor cable, proceed as follows: 1. Remove the vibration sensor cover cap. Figure 41: Vibration sensor cover cap 2. Ensure that the sensor cable plug and the socket on the sensor are dry and free of dirt. If this is not the case, clean and dry them with a cloth.

62 6796573/02 EN MSENSE® VAM 3. Plug in the sensor cable plug and screw it in by hand. Figure 42: Plugging in the sensor cable 4. Route the sensor cable on the transformer to the control cabinet with shielding to prevent mechanical damage and interference.

63 6796573/02 EN MSENSE® VAM 5. Shorten the sensor cable to the desired length. Loops or coil windings of an excessive length are not permitted when routing the cable. Figure 43: Sensor cable routing 1 Temperature sensor cable 2 Control cabinet 3 Vibration sensor cable 4 Transformer 5 On-load tap-changer head cover If the control cabinet is farther away, extend the sensor cable with a shielded cable in the motor drive cabinet or in a metal intermediate terminal box. Follow the information in the Cable recommendation [►Section 6.3.1, Page 51] section and implement continuous shielding.

64 6796573/02 EN MSENSE® VAM For the control cabinet connection, proceed as follows: 1. Connect the sensor cable shield to the grounding bar in the control cabi- net using a shielded clamp. When doing so, only expose the cable shield as much as is necessary for the shielded clamp. Figure 44: Sensor cable shield connection Tighten the cable screw connections on the control cabinet with the follow- ing tightening torques: M20: 8 Nm, M32: 20 Nm. 2. Connect the sensor cable in accordance with the connection diagram pro- vided (blue = signal, brown = signal ground, black = ground in control cab- inet). 6.3.7 Connecting the motor-drive unit controller to the monitoring system To synchronize the vibro-acoustic signals with the tap position change, it is necessary to measure the diverter switch operation in the motor-drive con- troller. With the integration solution in the motor-drive unit, this connection is already made at the factory. With the "standalone" and "integration solution in the customer control cabi- net" versions, you must make this connection yourself. To do so, connect the position transmitter module of the motor-drive unit to the DIO assembly of the vibro-acoustic monitoring system in accordance with the connection dia- gram provided. 6.3.8 Connecting the temperature sensor Depending on the application, one or more temperature sensors are in- cluded in the scope of delivery. When making the connection, follow the con- nection diagram on the associated dimensional drawing. Make the connec- tion to the control cabinet in accordance with the connection diagram pro- vided for the monitoring system.

65 6796573/02 EN MSENSE® VAM 6.3.9 Connecting additional leads (optional) Connect additional leads as necessary in accordance with the connection di- agram: ▪ Digital inputs and outputs ▪ Control system ▪ Visualization Routing information for connecting the control system or visualization When connecting the device to a control system or to your network for ac- cessing the visualization, observe the following recommendation on the ca- ble routing in the control cabinet: Figure 45: Recommendation on the cable routing in the control cabinet for the connection of the control system or visualization 6.3.10 Connecting the power supply You may only connect the control cabinet to circuits with an external over- current protection device and an isolating device with all poles disconnected so the equipment can be fully de-energized if required (service, maintenance etc.).

66 6796573/02 EN MSENSE® VAM Suitable equipment includes isolating devices in accordance with IEC 60947-1 and IEC 60947-3 (e.g. circuit breaker). Note the properties of the relevant circuits (voltage, maximum currents) when selecting the circuit breaker type. In addition, observe the following: ▪ It must be easy for the operator to access the isolating device ▪ The isolating device must be labeled for the device and circuits to be iso- lated ▪ The isolating device may not be a part of the power line ▪ The isolating device may not interrupt the main protective conductor You must connect the power supply circuit with a conductor cross-section of at least 2.5 mm2 (AWG 13) and protect it with a C6A or B6A type miniature circuit breaker. To connect the voltage supply, proceed as follows: ►Connect the power supply of the control cabinet to terminal X1 in accor- dance with the connection diagram provided. 6.4 Checking functional reliability To ensure that the device is wired correctly, check its functionality. NOTICE Damage to device and system periphery! An incorrectly connected device can lead to damage to the device and sys- tem periphery. ►Check the entire configuration before commissioning. To check the functionality, proceed as follows: ►Apply voltage to the control cabinet. ð The device's control system boots up; after a brief period, the relay switches the operating contact STATUS OK (DIO 28-15:1B). The device is fully mounted and can be configured. The actions required for this are described in the following chapter.

More information on this (e.g. data points) is to be found in the pro- vided supplement for the control system protocol. You do not need to set additional parameters for commissioning. 7.7 Performing tests Please contact Maschinenfabrik Reinhausen GmbH (MR) if any aspect of the tests is not clear.

73 6796573/02 EN MSENSE® VAM 7.7.1 Checking measured values and status of digital inputs and outputs Upon commissioning the device, check whether the measured values and status of digital inputs and outputs are plausible. To do so, use an additional measuring device if necessary in order to check the individual measured val- ues. To display the status of the digital inputs and outputs, proceed as follows: 1. Go to Information > Hardware. 2. Select the individual assemblies one after another and check the individ- ual measured values or the status of digital inputs and outputs. 3. If errors arise, check the measurement path and the wiring. 7.7.2 Performing function tests To ensure that the monitoring system functions seamlessly, you have to check the communication with the sensor and the automatic triggering func- tion after each installation or maintenance action as follows: 1. Check that the wiring of the sensor and the signal feedback is in accor- dance with the supplied circuit diagram. 2. Perform a few on-load tap-changes for all positions and in both directions and check the plausibility of the signal progression including the envelope curve in the monitoring system. 3. Check that the signals are being recorded and saved correctly. 4. Optional: Check the control system. ð The monitoring system is ready to function. 7.7.3 Electrical high-voltage tests on the transformer It is essential that you ensure only trained, instructed expert personnel who are familiar with and comply with the pertinent safety and technical regula- tions, who are aware of the potential risks, and who consistently use the oc- cupational safety equipment provided to prevent injury and property damage are assigned to perform such a transformer test. Note the following points before performing high voltage tests on the trans- former: ▪ Check that the ground connections on the control cabinet and the control cabinet fixings are free of paint. ▪ Only perform a high voltage test with the control cabinet door closed. ▪ Disconnect the sensor cable and other external connections to electronic components in the control cabinet to prevent damage through overvolt- age. ▪ When connecting the control cabinet's supply voltage, only use the bush- ings in the protective housing base intended for lead insertion. ▪ Guide all ground connecting leads to one central connection point (estab- lishment of suitable reference earth).

74 6796573/02 EN MSENSE® VAM ▪ Disconnect all electronic components before the high voltage test. Before a dielectric test of the wiring, remove all devices with a withstand voltage of < 1000 V. ▪ Remove leads used for testing before the high voltage test, because these function as antennas. ▪ Wherever possible, route the measurement leads and data leads sepa- rately to the energy cables. 7.7.4 Ground test For commissioning, carry out a ground test (check of the impedance of the protective bonding) in accordance with IEC 61010-1. Note the following in- formation: ▪ Test current: 2 times the measurement current of the overcurrent protec- tion device of the supply line. ▪ Test duration: 1 minute for each measurement point. ▪ The measured voltage between the measurement point and the protective conductor must be smaller than 10 V. Proceed as follows to carry out the ground test: 1. Feed the test current at the fixing screw of assembly DIO 28-15 or DIO 42-20 using a constant current source and measure the voltage between the measurement point and the protective conductor. ð The measured voltage must remain less than 10 V over a duration of 1 minute. Figure 53: Perform a ground test on the DIO assembly (sample representation of the DIO 28-15 assembly).

75 6796573/02 EN MSENSE® VAM 2. Feed the test current at the grounding terminal of the G1 PULS DIMEN- SION QS3.241 assembly using a constant current source and measure the voltage between the measurement point and the protective conductor. ð The measured voltage must remain less than 10 V over a duration of 1 minute. Figure 54: Perform a ground test on the G1 PULS DIMENSION QS3.241 assembly 7.7.5 Dielectric tests on transformer wiring Note the following points for dielectric testson the transformer wiring: The monitoring system has been put through dielectric tests before delivery. ►Before the dielectric test for the transformer wiring, disconnect the moni- toring system from the section to be tested to rule out increased compo- nent loading for those components fitted in the control cabinet.
