Maschinenfabrik Reinhausen GmbH 2019 27 5089542/05 EN MSENSE® BM 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 2019 28 5089542/05 EN MSENSE® BM 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 7: 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 2019 29 5089542/05 EN MSENSE® BM 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! If the product is delivered in sealed packaging, inspect this im- mediately. If the sealed packaging is damaged, do not under any circum- stances install or commission the packaged goods. Either re-dry the dried packaged goods as per the operating instructions, or contact the manu- facturer to agree on how to proceed. Failure to do so may result in dam- age to the packaged goods. ▪ 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 2019 30 5089542/05 EN MSENSE® BM 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 installation will take place. Do not open the sealed packaging until just before 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 packaged goods in an upright crate and protect against tip- ping out. If this is not done, the packaged goods may be damaged and se- rious injuries may result. ▪ Check completeness of accessories based on the delivery slip. Attachment points for lifting gear WARNING Risk of tipping and danger of falling load! Danger of death and damage to property due to tipping or falling load. ►Only trained and appointed persons may select the sling gear and secure the load. ►Do not walk under the hanging load. ►Use means of transport and lifting gear with a sufficient carrying capacity in accordance with the weight stated in the Technical data [►Section 14, Page 143] section. ▪ Control cabinet: – Retractable brackets on top left and right, opening size 25 x 25 mm.

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.

52 5089542/05 EN MSENSE® BM 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. 6.6 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.

53 5089542/05 EN MSENSE® BM 7 Commissioning 7.1 Determining the capacitance and dissipation factor of the bushings To ensure that the bushings are in the proper condition, Maschinenfabrik Reinhausen GmbH recommends taking an initial measurement on new bushings when commissioning the bushing monitoring. If you are retrofitting the bushing monitoring on bushings already in operation, an initial measure- ment is absolutely essential. To do this, use a suitable measuring device (Schering bridge) to measure the capacitance C1 and dissipation factor tanδ on the fitted bushings. Follow the notes in the operating instructions from the bushing manufacturer. Enter the measured values in the measured value log [►Section 15.1, Page 157]. 7.2 Establishing connection to visualization You can use the ETH1.1 interface or the optional ETH2.2 interface of the CPU assembly to establish the connection to the visualization. The inter- faces do not use a DHCP server. Therefore, you must assign a static IP ad- dress to your PC. To do this, observe the following configuration example: Interface Configuration Standard ETH1.1 IP address: 192.168.165.1 (not adjustable) PC IP address: 192.168.165.100 Subnet mask: 255.255.255.0 Optional ETH2.2 IP address: 192.0.1.203 (factory setting) [►Section 8.4, Page 66] Subnet mask: 255.255.255.0 PC IP address: 192.0.1.100 Subnet mask: 255.255.255.0 Table 9: Interface configuration example

54 5089542/05 EN MSENSE® BM Establishing a connection via the ETH1.1 interface To establish a connection via the ETH1.1 interface, proceed as follows: 1. Connect the PC and device using an Ethernet cable (RJ45 plug) via the ETH1.1 interface. Figure 42: Establishing a connection via the front interface 2. Assign a unique IP address to the PC in the same subnet as the device (e.g. 192.168.165.100). 3. Enter the visualization's IP address http://192.168.165.1, or if SSL encryption is active enter https://192.168.165.1, on the PC in the browser. ð The visualization is accessed. Establishing a connection via the ETH2.2 interface on the CPU module (optional) The device is supplied with the IP address 192.0.1.230 at the factory.

Figure 44: Setting the language 2. Select the desired language from the list box. 3. Press the Accept button to save the modified parameter. ð The "Restart device" dialog appears. 4. Restart the device to apply the changed language setting. 7.4 Setting date and time You can set the date and time in the following ways: ▪ Manually ▪ Time synchronization via control system (SCADA) ▪ Time synchronization via SNTP time server If you are using a control system, the device automatically synchronizes the date and time with the control system. If you would like to use an SNTP time server, you must set the required parameters. When doing so, observe the information provided in the Time synchroniza- tion [►Section 8.15, Page 105] section. 7.5 Setting the parameters Commissioning the device requires setting some parameters. You can set the necessary parameters with the help of the commissioning assistant or set each parameter individually. 7.5.1 Commissioning wizard If you want the device to help when setting the relevant parameters, you can use the commissioning wizard. The commissioning wizard provides a selec- tion of parameters that you can configure in order. A detailed description of each of the parameters can be found in the Opera- tion [►Section 8, Page 60] chapter. To call up the commissioning wizard, you will need the necessary access rights [►Section 8.16, Page 109]. When in delivery status, you can log in as the administrator as follows: ▪ User name: admin ▪ Password: admin

57 5089542/05 EN MSENSE® BM To set the parameters with the help of the commissioning wizard, proceed as follows: 1. Log in as a user with the necessary access rights. 2. Go to Settings > Commissioning wizard. Figure 45: Calling up the commissioning wizard 3. Press the Next button to launch the commissioning wizard. 4. Follow the on-screen instructions. Once you have entered all of the parameters relevant to commissioning, continue with the function test. 7.5.2 Setting the parameters manually If bushing monitoring with the option "Monitoring of 6 bushings" is used, the parameters for both field 1 (F1) and field 2 (F2) must be set. Field 1 and field 2 each describe a set consisting of 3 bushings respectively. If bushing monitoring with the option "Monitoring of 3 bushings" is used, only the pa- rameters for field 1 are displayed. Commissioning the bushing monitoring requires setting the following param- eters: Setting the transformer data for the reference system [►Section 8.5, Page 68] 1. Set primary transformer voltage. 2.

Setting control system protocol (optional) If you need a control system protocol [►Section 8.13, Page 84], you must set the parameters required for this. More information on this (e.g. data points) can be found in the enclosed supplement for the control system pro- tocol. 7.6 Performing standardization Once you have set all required parameters, you must perform a standardiza- tion for commissioning the device. The standardization is used to compen- sate for measurement tolerances along the measurement chain (bushing, bushing adapter and bushing coupling unit). Follow the notes on this in the following sections: ▪ Configuring capacitance monitoring [►Section 8.6.2, Page 69] ▪ Configuring dissipation factor monitoring [►Section 8.6.3, Page 72] 7.7 Performing tests Please contact Maschinenfabrik Reinhausen GmbH (MR) if any aspect of the tests is not clear. 7.7.1 Performing function tests To check that the monitoring system is functioning correctly, proceed as fol- lows: 1. Check the pending event messages [►Section 8.12.1, Page 81]. If event messages are pending, resolve the cause of the event and acknowledge the event. 2.

59 5089542/05 EN MSENSE® BM 7.7.2 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 undertaking 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 high voltage test if the control cabinet door is closed. ▪ Disconnect external connections to electronic components in the control cabinet to prevent damage from overvoltage. ▪ Remove the bushing adapter and fit the cap of the bushing test tap. ▪ 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). ▪ Disconnect all electronic components before the high voltage test. Before a dielectric test of the wiring, remove all devices with a withstand voltage of < 1,000 V. ▪ Remove leads used for testing before the high voltage test as these func- tion as antennas. ▪ Wherever possible, route the measurement leads and data leads sepa- rately to the energy cables. 7.7.3 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.

Field 1 and field 2 each describe a set consisting of 3 bushings respectively. If bushing monitoring with the option "Monitoring of 3 bushings" is used, only the pa- rameters for field 1 are displayed. To monitor the capacitance of the bushings, the following parameters must be set for commissioning the transformer: ▪ F1/F2-C: Activate cap. monitoring ▪ F1/F2-C: C1 Phase L1/L2/L3 ▪ F1/F2-C: ΔC1 > ▪ F1/F2-C: ΔC1 >> ▪ F1/F2-C: Perform standardization

71 5089542/05 EN MSENSE® BM Figure 52: Configuring bushing monitoring To set capacitance monitoring, proceed as follows: 1. Go to Settings > Parameters > Bushing monitoring > Bushing moni- toring field1/field2. 2. Select the desired parameter. 3. Set the parameter. 4. Press the Accept button to save the modified parameter. F1/F2-C: Activate capacitance monitoring You can use this parameter to activate or deactivate capacitance monitoring in field 1 or field 2. After being switched on, capacitance monitoring only becomes active once a delay time has elapsed (factory setting of 2 minutes) in order to avoid er- rors resulting from transients. F1/F2-C: C1 Phase L1/L2/L3 You can use these parameters to set the reference capacitance C1 for the bushings of phases L1, L2 and L3 in field 1 and field 2. The reference value is the value you have measured with an external measuring device for com- missioning [►Section 7.1, Page 53]. F1/F2 Limit values C: ΔC1 > and C: ΔC1 >> You can set two limit values for monitoring the bushings in field 1 and field 2: ▪ F1/F2-C: ΔC1 > ▪ F1/F2-C: ΔC1 >> If the limit values are exceeded, the monitoring system triggers an event message and issues a signal at the digital output.

72 5089542/05 EN MSENSE® BM Maschinenfabrik Reinhausen recommends the following limit values: F1/F2- C: ΔC1 >: 5%, F1/F2-C: ΔC1 >>: 10% F1/F2-C: Perform standardization You must perform standardization for field 1 and field 2 to commission the monitoring system. The standardization is used to compensate for measure- ment tolerances along the measurement chain (bushing, bushing adapter and bushing coupling unit). Only perform the standardization while commissioning the monitoring sys- tem and with bushings in good condition. Otherwise correct bushing moni- toring functionality cannot be guaranteed. To perform the standardization, proceed as follows: ü The transformer is in a stable state (typical load, no on-load tap-change operation or significant change in the transformer load, thermally stabi- lized). 1. Go to Settings > Parameters > Bushing monitoring > Bushing moni- toring field1/field2 > F1/F2-C: Perform standardization. 2. Select the Yes option. 3. Press the Accept button to perform the standardization. ð The standardization is carried out and the parameter is reset to the No option. 4. Check the event messages [►Section 8.12.1, Page 81] to see if the standardization was performed successfully. If this is not the case, resolve the cause of the error and repeat the standardization. 8.6.3 Configuring dissipation factor monitoring The device monitors the change in the difference of the dissipation factor tanδ between the phases. If the tanδ of all 3 phases changes in the same way (e.g. due to a temperature change), the difference in the dissipation fac- tor Δtanδ remains constant.

73 5089542/05 EN MSENSE® BM If the dissipation factor of one or two bushings changes, the difference in the dissipation factor also changes. If the difference in the dissipation factor is greater than the set limit value, the device triggers an event message. tanδ t Max. Min. Max. Min.

Field 1 and field 2 each describe a set consisting of 3 bushings respectively. If bushing monitoring with the option "Monitoring of 3 bushings" is used, only the pa- rameters for field 1 are displayed. To monitor the dissipation factor of the bushings, you must set the following parameters for commissioning the transformer: ▪ F1/F2-tanδ: Activate diss. factor monit. ▪ F1/F2-tanδ: tanδ phase L1/L2/L3 ▪ F1/F2-tanδ: Δtanδ > ▪ F1/F2-tanδ: Perform standardization

Go to Settings > Parameters > Bushing monitoring > Bushing moni- toring field1/field2. 2. Select the desired parameter. 3. Set the parameter. 4. Press the Accept button to save the modified parameter. F1/F2-tanδ: Activate dissipation factor monitoring You can use this parameter to activate or deactivate dissipation factor moni- toring in field 1 or field 2. After being switched on, dissipation factor monitoring only becomes active once a delay time has elapsed (measured value display after approx. 7 min- utes, monitoring after approx. 1 hour) in order to avoid errors resulting from transients. F1/F2-tanδ: tanδ phase L1/L2/L3 You can use these parameters to set the reference dissipation factor tanδ for the bushings of phases L1, L2 and L3 in field 1 or field 2. The reference value is the value you have measured with an external measuring device for commissioning [►Section 7.1, Page 53]. Limit value F1/F2-tanδ: Δtanδ > You can set a limit value for monitoring the bushings in field 1 or field 2. If the limit value is exceeded, the monitoring system triggers an event mes- sage and issues a signal at the digital output.

75 5089542/05 EN MSENSE® BM F1/F2-tanδ: Perform standardization You can use this parameter to perform a standardization of the dissipation factor monitoring in field 1 and field 2. This clears all of the measured and calculated values for dissipation factor monitoring. To perform the standardization, proceed as follows: 1. Go to Settings > Parameters > Bushing monitoring > Bushing moni- toring field1/field2 > F1/F2-tanδ: Perform standardization. 2. Select the Yes option. 3. Press the Accept button to perform the standardization. ð The standardization is carried out and the parameter is reset to the No option. 4. Check the event messages [►Section 8.12.1, Page 81] to see if the standardization was performed successfully. 8.6.4 Circuit breaker monitoring You can configure up to 4 digital inputs for monitoring the status messages of the circuit breakers in the reference system. This monitoring function is used for detecting whether the reference system is active (circuit breaker in ON position) or inactive (circuit breaker in OFF position). If circuit breaker monitoring is configured and a circuit breaker is reported to be in the OFF position, the device reacts as follows: ▪ Bushing monitoring is deactivated. ▪ You cannot perform standardization. When configuring this function, refer to the section Configuring digital inputs and outputs [►Section 8.11, Page 79]. If bushing monitoring with the option "Monitoring of 6 bushings" is used, you can configure up to 4 inputs for field 1 (F1) and for field 2 (F2) respectively. If bushing monitoring with the option "Monitoring of 3 bushings" is used, only the inputs for field 1 are displayed. Bushing monitoring is only deactivated for the respective field. 8.7 Displaying the state of the bushings The device displays the current state of the bushings and the following mea- sured values: ▪ Status indicator for the bushing based on the set limit values – Gray: Everything OK – Yellow: The capacitance difference ΔC1 is greater than the limit value ΔC1 > or the dissipation factor difference Δtanδ is greater than the limit value Δtanδ > – Red: The capacitance difference ΔC1 is greater than the limit value ΔC1 >>
