SETTING RECORD OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 1 SECTION 1 . INTRODUCTION The MiCOM P440 distance protection relays are fully numerical in their design, implementing all protection and non-protection functions in software. The relays employ a high degree of self-checking and, in the unlikely event of a failure, will give an alarm. As a result of this, the commissioning tests do not need to be as extensive as with non-numeric electronic or electro-mechanical relays. To commission numeric relays, it is only necessary to verify that the hardware is functioning correctly and the application-specific software settings have been applied to the relay. It is considered unnecessary to test every function of the relay if the settings have been verified by one of the following methods: • Extracting the settings applied to the relay using appropriate setting software (Preferred method) • Via the operator interface. To confirm that the product is operating correctly once the application-specific settings have been applied, a test should be performed on a single protection element. Unless previously agreed to the contrary, the customer will be responsible for determining the application-specific settings to be applied to the relay and for testing of any scheme logic applied by external wiring and/or configuration of the relay’s internal programmable scheme logic. Blank commissioning test and setting records are provided at the end of this chapter for completion as required. As the relay’s menu language is user-selectable, it is acceptable for the Commissioning Engineer to change it to allow accurate testing as long as the menu is restored to the customer’s preferred language on completion. To simplify the specifying of menu cell locations in these Commissioning Instructions, they will be given in the form [courier reference: COLUMN HEADING, Cell Text]. For example, the cell for selecting the menu language (first cell under the column heading) is located in the System Data column (column 00) so it would be given as [0001: SYSTEM DATA, Language]. Before carrying out any work on the equipment, the user should be familiar with the contents of the ‘safety section’ and chapter 2, ‘installation’, of this manual. ! OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 2 SECTION 2 . SETTING FAMILIARISATION When commissioning a MiCOM P440 relay for the first time, sufficient time should be allowed to become familiar with the method by which the settings are applied. Chapter 1 contains a detailed description of the menu structure of the relays. With the secondary front cover in place all keys except the [Enter] key are accessible. All menu cells can be read. LEDs and alarms can be reset. However, no protection or configuration settings can be changed, or fault and event records cleared. Removing the secondary front cover allows access to all keys so that settings can be changed, LEDs and alarms reset, and fault and event records cleared. However, menu cells that have access levels higher than the default level will require the appropriate password to be entered before changes can be made. Alternatively, if a portable PC is available together with suitable setting software (such as MiCOM S1), the menu can be viewed a page at a time to display a full column of data and text. This PC software also allows settings to be entered more easily, saved to a file on disk for future reference or printed to produce a setting record. Refer to the PC software user manual for details. If the software is being used for the first time, allow sufficient time to become familiar with its operation. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 3 SECTION 3 . EQUIPMENT REQUIRED FOR COMMISSIONING 3.1 Minimum Equipment Required Overcurrent test set with interval timer 110V ac voltage supply (if stage 1 of the overcurrent function is set directional) Multimeter with suitable ac current range, and ac and dc voltage ranges of 0-440V and 0-250V respectively Continuity tester (if not included in multimeter) Phase angle meter Phase rotation meter Note: Modern test equipment may contain many of the above features in one unit. 3.2 Optional Equipment Multi-finger test plug type MMLB01 (if test block type MMLG installed) An electronic or brushless insulation tester with a dc output not exceeding 500V (For insulation resistance testing when required). A portable PC, with appropriate software (This enables the rear communications port to be tested if this is to be used and will also save considerable time during commissioning). KITZ K-Bus to RS232 protocol converter (if RS485 K-Bus port is being tested and one is not already installed). RS485 to RS232 converter (if RS485 Modbus port is being tested). A printer (for printing a setting record from the portable PC). OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 4 SECTION 4 . PRODUCT CHECKS These product checks cover all aspects of the relay that need to be checked to ensure that it has not been physically damaged prior to commissioning, is functioning correctly and all input quantity measurements are within the stated tolerances. If the application-specific settings have been applied to the relay prior to commissioning, it is advisable to make a copy of the settings so as to allow their restoration later. This could be done by: • Obtaining a setting file on a diskette from the customer (This requires a portable PC with appropriate setting software for transferring the settings from the PC to the relay) • Extracting the settings from the relay itself (This again requires a portable PC with appropriate setting software) • Manually creating a setting record. This could be done using a copy of the setting record located at the end of this chapter to record the settings as the relay’s menu is sequentially stepped through via the front panel user interface. If password protection is enabled and the customer has changed password 2 that prevents unauthorised changes to some of the settings, either the revised password 2 should be provided, or the customer should restore the original password prior to commencement of testing. Note: In the event that the password has been lost, a recovery password can be obtained from ALSTOM by quoting the serial number of the relay. The recovery password is unique to that relay and will not work on any other relay. 4.1 With the Relay De-energised The following group of tests should be carried out without the auxiliary supply being applied to the relay and with the trip circuit isolated. The current and voltage transformer connections must be isolated from the relay for these checks. If an MMLG test block is provided, the required isolation can easily be achieved by inserting test plug type MMLB01 which effectively opencircuits all wiring routed through the test block. Before inserting the test plug, reference should be made to the scheme (wiring) diagram to ensure that this will not potentially cause damage or a safety hazard. For example, the test block may also be associated with protection current transformer circuits. It is essential that the sockets in the test plug which correspond to the current transformer secondary windings are linked before the test plug is inserted into the test block. DANGER: NEVER OPEN CIRCUIT THE SECONDARY CIRCUIT OF A CURRENT TRANSFORMER SINCE THE HIGH VOLTAGE PRODUCED MAY BE LETHAL AND COULD DAMAGE INSULATION. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 5 If a test block is not provided, the voltage transformer supply to the relay should be isolated by means of the panel links or connecting blocks. The line current transformers should be short-circuited and disconnected from the relay terminals. Where means of isolating the auxiliary supply and trip circuit (e.g. isolation links, fuses, MCB, etc.) are provided, these should be used. If this is not possible, the wiring to these circuits will have to be disconnected and the exposed ends suitably terminated to prevent them from being a safety hazard. 4.1.1 Visual Inspection Carefully examine the relay to see that no physical damage has occurred since installation. The rating information given under the top access cover on the front of the relay should be checked to ensure it is correct for the particular installation. Ensure that the case earthing connections, bottom left-hand corner at the rear of the relay case, are used to connect the relay to a local earth bar using an adequate conductor.

The heavy duty terminal block is fastened to the rear panel using four crosshead screws. These are located top and bottom between the first and second, and third and fourth, columns of terminals. Note: The use of a magnetic bladed screwdriver is recommended to minimize the risk of the screws being left in the terminal block or lost. Pull the terminal block away from the rear of the case and check that all the shorting switches being used are closed with a continuity tester. Table 1 shows the terminals between which shorting contacts are fitted.

The relay diagram number appears on the rating label under the top access cover on the front of the relay. The corresponding connection diagram will have been supplied with the ALSTOM order acknowledgement for the relay. If an MMLG test block is provided, the connections should be checked against the scheme (wiring) diagram. It is recommended that the supply connections are to the live side of the test block (coloured orange with the odd numbered terminals (1, 3, 5, 7 etc.)). The auxiliary supply is normally routed via terminals 13 (supply positive) and 15 (supply negative), with terminals 14 and 16 connected to the relay’s positive and negative auxiliary supply terminals respectively. However, check the wiring against the schematic diagram for the installation to ensure compliance with the customer’s normal practice. 4.1.4 Insulation Insulation resistance tests only need to be done during commissioning if it is required for them to be done and they haven’t been performed during installation. Isolate all wiring from the earth and test the insulation with an electronic or brushless insulation tester at a dc voltage not exceeding 500V. Terminals of the same circuits should be temporarily connected together. The main groups of relay terminals are: a) b) c) d) e) f) g) Voltage transformer circuits. Current transformer circuits Auxiliary voltage supply. Field voltage output and opto-isolated control inputs. Relay contacts. RS485 communication port. Case earth. The insulation resistance should be greater than 100MΩ at 500V. On completion of the insulation resistance tests, ensure all external wiring is correctly reconnected to the unit. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 4.1.5 Watchdog Contacts OG 1.1671-B Volume 2 Chapter 3 Page 8 Using a continuity tester, check that the normally closed watchdog contacts are in the states given in Table 2 for a de-energised relay. Terminals Contact State Relay De-energised Relay Energised Open (P441) Closed F11-F12 (P442) J11-J12 N11-N12 (P444) (P441) Open F13-F14 (P442) J13-J14 N13-N14 (P444) Table 2 Watchdog Contact Status 4.1.6 Auxiliary Supply Closed The relay can be operated from either a dc only or an ac/dc auxiliary supply depending on the relay’s nominal supply rating. The incoming voltage must be within the operating range specified in Table 3. Without energising the relay, measure the auxiliary supply to ensure it is within the operating range. Nominal Supply Rating DC [AC rms] 24/54V 48/110V 110/250V [-] [30/100V] [100/240V] DC Operating Range 19 - 65V 37 - 150V 87 - 300V AC Operating Range 24 - 110V 80 - 265V Table 3 Operational Range of Auxiliary Supply It should be noted that the relay can withstand an ac ripple of up to 12% of the upper rated voltage on the dc auxiliary supply. DO NOT ENERGISE THE RELAY USING THE BATTERY CHARGER WITH THE BATTERY DISCONNECTED AS THIS CAN IRREPARABLY DAMAGE THE RELAY’S POWER SUPPLY CIRCUITRY. Energise the relay if the auxiliary supply is within the operating range. If an MMLG test block is provided, it may be necessary to link across the front of the test plug to connect the auxiliary supply to the relay. ! ! OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 9 4.2 With the Relay Energised The following group of tests verify that the relay hardware and software is functioning correctly and should be carried out with the auxiliary supply applied to the relay. The current and voltage transformer connections must remain isolated from the relay for these checks. 4.2.1 Watchdog Contacts Using a continuity tester, check the watchdog contacts are in the states given in Table 3 for an energized relay. 4.2.2 Date and Time The date and time should now be set to the correct values. The method of setting will depend on whether accuracy is being maintained via the optional Inter-Range Instrumentation Group standard B (IRIG-B) port on the rear of the relay. 4.2.2.1 With an IRIG-B signal If a satellite time clock signal conforming to IRIG-B is provided and the relay has the optional IRIG-B port fitted, the satellite clock equipment should be energised. To allow the relay’s time and date to be maintained from an external IRIG-B source cell [0804: DATE and TIME, IRIG-B Sync] must be set to ‘Enabled’. Ensure the relay is receiving the IRIG-B signal by checking that cell [0805: DATE and TIME, IRIG-B Status] reads ‘Active’. Once the IRIG-B signal is active, adjust the time offset of the universal co-ordinated time (satellite clock time) on the satellite clock equipment so that local time is displayed. Check the time, date and month are correct in cell [0801: DATE and TIME, Date/Time]. The IRIG-B signal does not contain the current year so it will need to be set manually in this cell. In the event of the auxiliary supply failing, with a battery fitted in the compartment behind the bottom access cover, the time and date will be maintained. Therefore, when the auxiliary supply is restored, the time and date will be correct and not need to be set again. To test this, remove the IRIG-B signal, then remove the auxiliary supply from the relay. Leave the relay de-energized for approximately 30 seconds. On reenergisation, the time in cell [0801: DATE and TIME, Date/Time] should be correct. Reconnect the IRIG-B signal. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 10 4.2.2.2 Without an IRIG-B signal If the time and date is not being maintained by an IRIG-B signal, ensure that cell [0804: DATE and TIME, IRIG-B Sync] is set to ‘Disabled’. Set the date and time to the correct local time and date using cell [0801: DATE and TIME, Date/Time]. In the event of the auxiliary supply failing, with a battery fitted in the compartment behind the bottom access cover, the time and date will be maintained. Therefore when the auxiliary supply is restored the time and date will be correct and not need to be set again. To test this, remove the auxiliary supply from the relay for approximately 30 seconds. On re-energisation, the time in cell [0801: DATE and TIME, Date/Time] should be correct. 4.2.3 Light Emitting Diodes (LEDs) On power up the green LED should have illuminated and stayed on indicating that the relay is healthy. The relay has non-volatile memory which remembers the state (on or off) of the alarm, trip and, if configured to latch, user-programmable LED indicators when the relay was last energised from an auxiliary supply. Therefore these indicators may also illuminate when the auxiliary supply is applied. If any of these LEDs are on then they should be reset before proceeding with further testing. If the LEDs successfully reset (the LED goes out), there is no testing required for that LED because it is known to be operational. Testing the alarm and out of service leds The alarm and out of service LEDs can be tested using the COMMISSIONING TESTS menu column. Set cell [0F0D: COMMISSIONING TESTS, Test Mode] to ‘Enabled’. Check that the alarm and out of service LEDs illuminate. It is not necessary to return cell [0F0D: COMMISSIONING TESTS, Test Mode] to ‘Disabled’ at this stage because test mode will be required for later tests. Testing the trip led The trip LED can be tested by initiating a manual circuit breaker trip from the relay. However, the trip LED will operate during the setting checks performed later. Therefore no further testing of the trip LED is required at this stage. Testing the user-programmable leds To test the user-programmable LEDs set cell [0F10: COMMISSIONING TESTS, Test LEDs] to ‘Apply Test’. Check that all 8 LEDs on the right-hand side of the relay illuminate. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 11 4.2.4 Field Voltage Supply The relay generates a field voltage of nominally 48V that should be used to energise the opto-isolated inputs. Measure the field voltage across the terminals given in Table 5. Check that the field voltage is present at each positive and negative terminal and that the polarity is correct. Repeat for terminals 8 and 10. Supply rail P441 +ve –ve F7 & F8 F9 & F10 Terminals P442 J7 & J8 J9 & J10 P444 N7 & N8 N9 & N10 Table 4 Field Voltage Terminals 4.2.5 Input Opto-isolators This test checks that all the opto-isolated inputs are functioning correctly. The P441 relays have 8 opto-isolated inputs while P442 relays have 16 opto-isolated inputs and P444 relays have 24 opto-isolated inputs. The opto-isolated inputs should be energised one at a time. Ensuring correct polarity, connect the field supply voltage to the appropriate terminals for the input being tested. The opto-isolated input terminal allocations are given in Table 5. Note: The opto-isolated inputs may be energised from an external 50V battery in some installations. Check that this is not the case before connecting the field voltage otherwise damage to the relay may result. The status of each opto-isolated input can be viewed using cell [0020: SYSTEM DATA, Opto I/P Status], a ‘1’ indicating an energised input and a ‘0’ indicating a de-energised input. When each opto-isolated input is energised one of the characters on the bottom line of the display will change to the value shown in Table 5 to indicate the new state of the inputs.

To select output relay 1 for testing, set cell [0F0E: COMMISSIONING TESTS, Test Pattern] as shown in Table 6. Connect an continuity tester across the terminals corresponding to output relay 1 given in Table 6. To operate the output relay set cell [0F0F: COMMISSIONING TESTS, Contact Test] to ‘Apply Test’. Operation will be confirmed by the continuity tester operating for a normally open contact and ceasing to operate for a normally closed contact. Reset the output relay by setting cell [0F0F: COMMISSIONING TESTS, Contact Test] to ‘Remove Test’. Note: It should be ensured that thermal ratings of anything connected to the output relays during the contact test procedure is not exceeded by the associated output relay being operated for too long. It is therefore advised that the time between application and removal of contact test is kept to the minimum. Repeat the test for relays 2 to 14 for P441 relays or relays 2 to 21 for P442 relays or relays 2 to 32 for P444 relays.

It is not the intention of the test to verify the operation of the complete system from the relay to the remote location, just the relay’s rear communications port and any protocol converter necessary. 4.2.7.1 Courier Communications If a K-Bus to RS232 KITZ protocol converter is installed, connect a portable PC running the appropriate software to the incoming (remote from relay) side of the protocol converter. If a KITZ protocol converter is not installed, it may not be possible to connect the PC to the type installed. In this case a KITZ protocol converter and portable PC running appropriate software should be temporarily connected to the relay’s K-Bus port. The terminal numbers for the relay’s K-Bus port are given in Table 7. However, as the installed protocol converter is not being used in the test, only the correct operation of the relay’s K-Bus port will be confirmed.

All relays will leave the factory set for operation at a system frequency of 50Hz. If operation at 60Hz is required then this must be set in cell [0009: SYSTEM DATA, Frequency]. Apply current equal to the line current transformer secondary winding rating to the each current transformer input of the corresponding rating in turn, checking its magnitude using a multimeter. Refer to Table 9 for the corresponding reading in the relay’s MEASUREMENTS 1 column and record the value displayed.

SETTING CHECKS The setting checks ensure that all of the application-specific relay settings (i.e. both the relay’s function and programmable scheme logic settings) for the particular installation have been correctly applied to the relay. If the application-specific settings are not available, ignore sections 5.1 and 5.2. 5.1 Apply Application-Specific Settings There are two methods of applying the settings: • Transferring them from a pre-prepared setting file to the relay using a portable PC running the appropriate software via the relay’s front RS232 port, located under the bottom access cover, or rear communications port (with a KITZ protocol converter connected). This method is the preferred for transferring function settings as it is much faster and there is less margin for error. If programmable scheme logic other than the default settings with which the relay is supplied are to be used then this is the only way of changing the settings. If a setting file has been created for the particular application and provided on a diskette, this will further reduce the commissioning time and should always be the case where programmable scheme logic changes are to be applied to the relay. • Enter them manually via the relay’s operator interface. This method is not suitable for changing the programmable scheme logic. 5.2 Check Application-Specific Settings The settings applied should be carefully checked against the required applicationspecific settings to ensure they have been entered correctly. However, this is not considered essential if a customer-prepared setting file has been transferred to the relay using a portable PC. There are two methods of checking the settings: • Extract the settings from the relay using a portable PC running the appropriate software via the front RS232 port, located under the bottom access cover, or rear communications port (with a KITZ protocol converter connected). Compare the settings transferred from the relay with the original written applicationspecific setting record. (For cases where the customer has only provided a printed copy of the required settings but a portable PC is available). • Step through the settings using the relay’s operator interface and compare them with the original application-specific setting record. Unless previously agreed to the contrary, the application-specific programmable scheme logic will not be checked as part of the commissioning tests. Due to the versatility and possible complexity of the programmable scheme logic, it is beyond the scope of these commissioning instructions to detail suitable test procedures. Therefore, when programmable scheme logic tests must be performed, written tests which will satisfactorily demonstrate the correct operation of the application-specific scheme logic should be devised by the Engineer who created it. These should be provided to the Commissioning Engineer together with the diskette containing the programmable scheme logic setting file.

Please refer to publication ME 1.1671 for testing instructions of the impedance characteristics. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 20 5.4 Demonstrate Correct Overcurrent Function Operation This test, performed on stage 1 of the overcurrent protection function in setting group 1, demonstrates that the relay is operating correctly at the applicationspecific settings. It is not considered necessary to check the boundaries of operation where cell [3502: GROUP 1 OVERCURRENT, I>1 Direction] is set to ‘Directional Fwd’ or ‘Directional Rev’ as the test detailed already confirms the correct functionality between current and voltage inputs, processor and outputs and earlier checks confirmed the measurement accuracy is within the stated tolerance. 5.4.1 Connect the Test Circuit Determine which output relay has been selected to operate when an I>1 trip occurs by viewing the relay’s programmable scheme logic. The programmable scheme logic can only be changed using the appropriate software. If this software has not been available then the default output relay allocations will still be applicable. If the trip outputs are phase-segregated (i.e. a different output relay allocated for each phase), the relay assigned for tripping on ‘A’ phase faults should be used. If stage 1 is not mapped directly to an output relay in the programmable scheme logic, output relay 3 should be used for the test as it operates for any trip condition. The associated terminal numbers can be found either from the external connection diagram (Appendix B) or Table 5. Connect the output relay so that its operation will trip the test set and stop the timer. Connect the current output of the test set to the ‘A’ phase current transformer input of the relay (terminals C3 and C2 where 1A current transformers are being used and terminals C1 and C2 for 5A current transformers). If [3502: GROUP 1 OVERCURRENT, I>1 Direction] is set to ‘Directional Fwd’, the current should flow out of terminal C2 but into C2 if set to ‘Directional Rev’. If cell [351D: GROUP 1 OVERCURRENT, VCO Status] is set to ‘Enabled’ (overcurrent function configured for voltage controlled overcurrent operation) or [3502: GROUP 1 OVERCURRENT, I>1 Direction] has been set to ‘Directional Fwd’ or ‘Directional Rev’ then rated voltage should be applied to terminals C19 and C22. Ensure that the timer will start when the current is applied to the relay. Note: If the timer does not start when the current is applied and stage 1 has been set for directional operation, the connections may be incorrect for the direction of operation set. Try again with the current connections reversed. 5.4.2 Perform the Test Ensure that the timer is reset. Apply a current of twice the setting in cell [3503: GROUP 1 OVERCURRENT, I>1 Current Set] to the relay and note the time displayed when the timer stops. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 21 5.4.3 Check the Operating Time Check that the operating time recorded by the timer is within the range shown in Table 12. Note: Except for the definite time characteristic, the operating times given in Table 12 are for a time multiplier or time dial setting of 1. Therefore, to obtain the operating time at other time multiplier or time dial settings, the time given in Table 12 must be multiplied by the setting of cell [3505: GROUP 1 OVERCURRENT, I>1 TMS] for IEC and UK characteristics or cell [3506: GROUP 1 OVERCURRENT, Time Dial] for IEEE and US characteristics. In addition, for definite time and inverse characteristics there is an additional delay of up to 0.02 second and 0.08 second respectively that may need to be added to the relay’s acceptable range of operating times. For all characteristics, allowance must be made for the accuracy of the test equipment being used.

To test the first autoreclose cycle, set cell [0F11: COMMISSIONING TESTS, Test Autoreclose] to “3 Pole Test”. The relay will perform a trip/reclose cycle. Repeat this operation to test the subsequent autoreclose cycles. Check all output relays used for circuit breaker tripping and closing, blocking other devices, etc. operate at the correct times during the trip/close cycle. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 22 SECTION 6 . ON-LOAD CHECKS Remove all test leads, temporary shorting leads, etc. and replace any external wiring that has been removed to allow testing. If it has been necessary to disconnect any of the external wiring from the relay in order to perform any of the foregoing tests, it should be ensured that all connections are replaced in accordance with the relevant external connection or scheme diagram. The following on-load measuring checks ensure the external wiring to the current and voltage inputs is correct but can only be carried out if there are no restrictions preventing the energisation of the plant being protected. 6.1 Voltage Connections Using a multimeter measure the voltage transformer secondary voltages to ensure they are correctly rated. Check that the system phase rotation is correct using a phase rotation meter. Compare the values of the secondary phase voltages with the relay’s measured values, which can be found in the MEASUREMENTS 1 menu column. If cell [0D02: MEASURE’T SETUP, Local Values] is set to ‘Secondary’, the values displayed on the relay should be equal to the applied secondary voltage. The relay values should be within 1% of the applied secondary voltages. However, an additional allowance must be made for the accuracy of the test equipment being used. If cell [0D02: MEASURE’T SETUP, Local Values] is set to ‘Primary’, the values displayed on the relay should be equal to the applied secondary voltage multiplied the corresponding voltage transformer ratio set in the ‘VT & CT RATIOS’ menu column (see Table 13). Again the relay values should be within 1% of the expected value, plus an additional allowance for the accuracy of the test equipment being used.

Check that the current transformer polarities are correct by measuring the phase angle between the current and voltage, either against a phase meter already installed on site and known to be correct or by determining the direction of power flow by contacting the system control centre. Ensure the current flowing in the neutral circuit of the current transformers is negligible. Compare the values of the secondary phase currents and phase angle with the relay’s measured values, which can be found in the MEASUREMENTS 1 menu column. Note: Under normal load conditions the earth fault function will measure little, if any, current. It is therefore necessary to simulate a phase to neutral fault. This can be achieved by temporarily disconnecting one or two of the line current transformer connections to the relay and shorting the terminals of these current transformer secondary windings. If cell [0D02: MEASURE’T SETUP, Local Values] is set to ‘Secondary’, the currents displayed on the relay should be equal to the applied secondary current. The relay values should be within 1% of the applied secondary currents. However, an additional allowance must be made for the accuracy of the test equipment being used. If cell [0D02: MEASURE’T SETUP, Local Values] is set to ‘Secondary’, the currents displayed on the relay should be equal to the applied secondary current multiplied by the corresponding current transformer ratio set in ‘VT & CT RATIOS’ menu column (see Table 9). Again the relay values should be within 1% of the expected value, plus an additional allowance for the accuracy of the test equipment being used. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 24 SECTION 7 . FINAL CHECKS The tests are now complete. Remove all test or temporary shorting leads, etc. If it has been necessary to disconnect any of the external wiring from the relay in order to perform the wiring verification tests, it should be ensured that all connections are replaced in accordance with the relevant external connection or scheme diagram. Ensure that the relay has been restored to service by checking that cell [0F0D: COMMISSIONING TESTS, Test Mode] is set to ‘Disabled’. If the relay is in a new installation or the circuit breaker has just been maintained, the circuit breaker maintenance and current counters should be zero. These counters can be reset using cell [0608: CB CONDITION, Reset All Values]. If the required access level is not active, the relay will prompt for a password to be entered so that the setting change can be made. If a MMLG test block is installed, remove the MMLB01 test plug and replace the MMLG cover so that the protection is put into service. Ensure that all event records, fault records, disturbance records, alarms and LEDs have been reset before leaving the relay. If applicable, replace the secondary front cover on the relay. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 25 SECTION 8 . MAINTENANCE 8.1 Maintenance Period It is recommended that products supplied by ALSTOM T&D Protection & Control receive regular monitoring after installation. As with all products some deterioration with time is inevitable. In view of the critical nature of protective relays and their infrequent operation, it is desirable to confirm that they are operating correctly at regular intervals. ALSTOM protective relays are designed for a life in excess of 20 years. MiCOM P440 distance relays are self-supervising and so require less maintenance than earlier designs of relay. Most problems will result in an alarm so that remedial action can be taken. However, some periodic tests should be done to ensure that the relay is functioning correctly and the external wiring is intact. If a Preventative Maintenance Policy exists within the customer’s organisation then the recommended product checks should be included in the regular program. Maintenance periods will depend on many factors, such as: • the operating environment • the accessibility of the site • the amount of available manpower • the importance of the installation in the power system • the consequences of failure 8.2 Maintenance Checks Although some functionality checks can be performed from a remote location by utilising the communications ability of the relays, these are predominantly restricted to checking that the relay is measuring the applied currents and voltages accurately, and checking the circuit breaker maintenance counters. Therefore it is recommended that maintenance checks are performed locally (i.e. at the substation itself). ! 8.2.1 BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT, THE USER SHOULD BE FAMILIAR WITH THE ‘SAFETY SECTION’ AND CHAPTER 2, ‘INSTALLATION’, OF THIS MANUAL. Alarms The alarm status LED should first be checked to identify if any alarm conditions exist. If so, press the read key [] repeatedly to step the alarms. Clear the alarms to extinguish the LED. 8.2.2 Opto-isolators The opto-isolated inputs can be checked to ensure that the relay responds to their energisation by repeating the commissioning test detailed in Section 4.2.5 of this chapter. 8.2.3 Output Relays The output relays can be checked to ensure that they operate by repeating the commissioning test detailed in Section 4.2.6 of this chapter. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 8.2.4 Measurement accuracy OG 1.1671-B Volume 2 Chapter 3 Page 26 If the power system is energised, the values measured by the relay can be compared with known system values to check that they are in the approximate range that is expected. If they are then the analogue/digital conversion and calculations are being performed correctly by the relay. Suitable test methods can be found in Sections 6.1 and 6.2 of this chapter. Alternatively, the values measured by the relay can be checked against known values injected into the relay via the test block, if fitted, or injected directly into the relay terminals. Suitable test methods can be found in Sections 4.2.8 and 4.2.9 of this chapter. These tests will prove the calibration accuracy is being maintained. 8.3 Method of Repair If the relay should develop a fault whilst in service, depending on the nature of the fault, the watchdog contacts will change state and an alarm condition will be flagged. Due to the extensive use of surface-mount components faulty PCBs should be replaced as it is not possible to perform repairs on damaged circuits. Thus either the complete relay or just the faulty PCB, identified by the in-built diagnostic software, can be replaced. Advice about identifying the faulty PCB can be found in Chapter 4, ‘Problem Analysis’. The preferred method is to replace the complete relay as it ensures that the internal circuitry is protected against electrostatic discharge and physical damage at all times and overcomes the possibility of incompatibility between replacement PCBs. However, it may be difficult to remove an installed relay due to limited access in the back of the cubicle and rigidity of the scheme wiring. Replacing PCBs can reduce transport costs but requires clean, dry conditions on site and higher skills from the person performing the repair. However, if the repair is not performed by an approved service centre, the warranty will be invalidated. ! 8.3.1 BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT, THE USER SHOULD BE FAMILIAR WITH THE ‘SAFETY SECTION’ AND CHAPTER 2, ‘INSTALLATION’, OF THIS MANUAL. THIS SHOULD ENSURE THAT NO DAMAGE IS CAUSED BY INCORRECT HANDLING OF THE ELECTRONIC COMPONENTS. Replacing the Complete Relay The case and rear terminal blocks have been designed to facilitate removal of the complete relay should replacement or repair become necessary without having to disconnect the scheme wiring. Before working at the rear of the relay, isolate all voltage and current supplies to the relay. Note: The MiCOM range of relays have integral current transformer shorting switches which will close when the heavy duty terminal block is removed. Disconnect the relay earth connection from the rear of the relay. There are two types of terminal block used on the relay, medium and heavy duty, which are fastened to the rear panel using crosshead screws, as in Figure 2. Note: The use of a magnetic bladed screwdriver is recommended to minimise the risk of the screws being left in the terminal block or lost. Without exerting excessive force or damaging the scheme wiring, pull the terminal blocks away from their internal connectors. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 27 Remove the screws used to fasten the relay to the panel, rack, etc. These are the screws with the larger diameter heads that are accessible when the access covers fitted and open. ! IF THE TOP AND BOTTOM ACCESS COVERS HAVE BEEN REMOVED, DO NOT REMOVE THE SCREWS WITH THE SMALLER DIAMETER HEADS WHICH ARE ACCESSIBLE. THESE SCREWS HOLD THE FRONT PANEL ON THE RELAY. Withdraw the relay from the panel, rack, etc. carefully because it will be heavy due to the internal transformers. To reinstall the repaired or replacement relay follow the above instructions in reverse, ensuring that each terminal block is relocated in the correct position and the case earth, IRIG-B and fibre optic connections are replaced. Once reinstallation is complete the relay should be recommissioned using the instructions in sections 1 to 7 inclusive of this chapter. 8.3.2 Replacing a PCB If the relay fails to operate correctly refer to Chapter 4, ‘Problem Analysis’, to help determine which PCB has become faulty. To replace any of the relay’s PCBs it is necessary to first remove the front panel. Before removing the front panel to replace a PCB the auxiliary supply must be removed. It is also strongly recommended that the voltage and current transformer connections and trip circuit are isolated. Open the top and bottom access covers. With size 60TE cases the access covers have two hinge-assistance T-pieces which clear the front panel moulding when the access covers are opened by more than 90°, thus allowing their removal. If fitted, remove the transparent secondary front cover. A description of how to do this is given in Chapter 1, ‘Introduction’. By slightly bending the access covers at one end, the end pivot can be removed from its socket and the access cover removed to give access to the screws that fasten the front panel to the case. The size 40TE case has four crosshead screws fastening the front panel to the case, one in each corner, in recessed holes. The size 60TE case has an additional two screws, one midway along each of the top and bottom edges of the front plate. Undo and remove the screws. ! DO NOT REMOVE THE SCREWS WITH THE LARGER DIAMETER HEADS WHICH ARE ACCESSIBLE WHEN THE ACCESS COVERS ARE FITTED AND OPEN. THESE SCREWS HOLD THE RELAY IN ITS MOUNTING (PANEL OR CUBICLE). When the screws have been removed, the complete front panel can be pulled forward and separated from the metal case. Caution should be observed at this stage because the front panel is connected to the rest of the relay circuitry by a 64way ribbon cable. The ribbon cable is fastened to the front panel using an IDC connector; a socket on the cable itself and a plug with locking latches on the front panel. Gently push the two locking latches outwards which will eject the connector socket slightly. Remove the socket from the plug to disconnect the front panel.

Figures 3 and 4 show the PCB locations for the distance relays in size 40TE (P441) and size 60TE (P442) cases respectively. The 64-way ribbon cable to the front panel also provides the electrical connections between PCBs with the connections being via IDC connectors. The slots inside the case to hold the PCBs securely in place each correspond to a rear terminal block. Looking from the front of the relay these terminal blocks are labelled from right to left. Note: To ensure compatibility, always replace a faulty PCB with one of an identical part number. Table 14 lists the part numbers of each PCB type.

Place the front panel with the user interface face-down and remove the six screws from the metallic screen, as shown in Figure 5. Remove the metal plate. There are two further screws, one each side of the rear of the battery compartment moulding, that hold the main processor PCB in position. Remove these screws. The user interface keypad is connected to the main processor board via a flex-strip ribbon cable. Carefully disconnect the ribbon cable at the PCB-mounted connector as it could easily be damaged by excessive twisting. Figure 5 Front Panel Assembly OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 30 The front panel can then be re-assembled with a replacement PCB using the reverse procedure, ensuring that the ribbon cable is reconnected to the main processor board and all eight screws are re-fitted. Refit the front panel using the reverse procedure to that given in section 8.3.2. After refitting and closing the access covers on case sizes 60TE, press at the location of the hinge-assistance T-pieces so that they click back into the front panel moulding. After replacement of the main processor board, all the settings required for the application will need to be re-entered. Therefore, it is useful if an electronic copy of the application-specific settings is available on disk. Although this is not essential, it can reduce the time taken to re-enter the settings and hence the time the protection is out of service. Once the relay has been reassembled after repair, it should be recommissioned in accordance with the instructions in sections 1 to 7 inclusive of this chapter. 8.3.2.2 Replacement of the IRIG-B board Depending on the model number of the relay, the IRIG-B board may have connections for IRIG-B signals, IEC60870-5-103 (VDEW) communications, both or not be present at all. To replace a faulty board, disconnect all IRIG-B and/or IEC60870-5-103 connections at the rear of the relay. The module is secured in the case by two screws accessible from the rear of the relay, one at the top and another at the bottom, as shown in Figure 6. Remove these screws carefully as they are not captive in the rear panel of the relay. Figure 6 Location of Securing Screws for IRIG-B Board Gently pull the IRIG-B board forward and out of the case. To help identify that the correct board has been removed, Figure 7 illustrates the layout of the IRIG-B board with both IRIG-B and IEC60870-5-103 options fitted (ZN0007 003). The other versions (ZN0007 001 and ZN0007 002) use the same PCB layout but with less components fitted. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 31 Figure 7 Typical IRIG-B Board The replacement PCB should be carefully slotted into the appropriate slot, ensuring that it is pushed fully back on to the rear terminal blocks and the securing screws are re-fitted. Reconnect all IRIG-B and/or IEC60870-5-103 connections at the rear of the relay. Refit the front panel using the reverse procedure to that given in section 8.3.2. After refitting and closing the access covers on case sizes 60TE, press at the location of the hinge-assistance T-pieces so that they click back into the front panel moulding. Once the relay has been reassembled after repair, it should be recommissioned in accordance with the instructions in sections 1 to 7 inclusive of this chapter. 8.3.2.3 Replacement of the input module The input module comprises of two boards fastened together, the transformer board and the input board. The module is secured in the case by two screws on its right-hand side, accessible from the front of the relay, as shown in Figure 8. Remove these screws carefully as they are not captive in the front plate of the module. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 32 Figure 8 Location of Securing Screws for Input Module On the right-hand side of the analogue input module there is a small metal tab which brings out a handle. Grasping this handle firmly, pull the module forward, away from the rear terminal blocks. A reasonable amount of force will be required to achieve this due to the friction between the contacts of two terminal blocks, one medium duty and one heavy duty. Note: Care should be taken when withdrawing the input module as it will suddenly come loose once the friction of the terminal blocks has been overcome. This is particularly important with loose relays as the metal case will need to be held firmly whilst the module is withdrawn. Remove the module from the case, taking care as it is heavy because it contains all the relay’s input voltage and current transformers. The replacement module can be slotted in using the reverse procedure, ensuring that it is pushed fully back on to the rear terminal blocks and the securing screws are re-fitted. Note: The transformer and input boards within the module are calibrated together with the calibration data being stored on the input board. Therefore it is recommended that the complete module is replaced to avoid on-site recalibration having to be performed. Refit the front panel using the reverse procedure to that given in section 8.3.2. After refitting and closing the access covers on case sizes 60TE, press at the location of the hinge-assistance T-pieces so that they click back into the front panel moulding. Once the relay has been reassembled after repair, it should be recommissioned in accordance with the instructions in sections 1 to 7 inclusive of this chapter. 8.3.2.4 Replacement of the power supply board The power supply board is fastened to a relay board to form the power supply module and is located on the extreme left-hand side of all MiCOM distance relays. Pull the power supply module forward, away from the rear terminal blocks and out of the case. A reasonable amount of force will be required to achieve this due to the friction between the contacts of the two medium duty terminal blocks. The two boards are held together with push-fit nylon pillars and can be separated by pulling them apart. Care should be taken when separating the boards to avoid OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 33 damaging the inter-board connectors located near the lower edge of the PCBs towards the front of the power supply module. The power supply board is the one with two large electrolytic capacitors on it that protrude through the other board that forms the power supply module. To help identify that the correct board has been removed, Figure 9 illustrates the layout of the power supply board for all voltage ratings. Figure 9 Typical Power Supply Board Re-assemble the module with a replacement board ensuring the inter-board connectors are firmly pushed together and the four push-fit nylon pillars are securely located in their respective holes in each PCB. Slot the power supply module back into the relay case, ensuring that it is pushed fully back on to the rear terminal blocks. Refit the front panel using the reverse procedure to that given in section 8.3.2. After refitting and closing the access covers on case sizes 60TE, press at the location of the hinge-assistance T-pieces so that they click back into the front panel moulding. Once the relay has been reassembled after repair, it should be recommissioned in accordance with the instructions in sections 1 to 7 inclusive of this chapter. 8.3.2.5 Replacement of the relay board in the power supply module Remove and replace the relay board in the power supply module as described in 8.3.2.4 above. The relay board is the one with the board with holes cut in it to allow the transformer and two large electrolytic capacitors to protrude through. To help identify that the correct board has been removed, Figure 10 illustrates the layout of the relay board. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 34 Figure 10 Typical Relay Board Ensure the setting of the link (located above IDC connector) on the replacement relay board is the same as the one being replaced before replacing the module in the relay case. Once the relay has been reassembled after repair, it should be recommissioned in accordance with the instructions in sections 1 to 7 inclusive of this chapter. 8.3.2.6 Replacement of the extra relay board (P442 1 P444 only) The P442 distance relay has two additional boards to the P441 and the P444 four additional boards to the P441. Some of these boards provides extra output relays and optically-isolated inputs. To remove it, gently pull the faulty PCB forward and out of the case. If the relay board is being replaced, ensure the setting of the link (located above IDC connector) on the replacement relay board is the same as the one being replaced. To help identify that the correct board has been removed, Figures 10 and 11 illustrate the layout of the relay and opto boards respectively. The replacement PCB should be carefully slotted into the appropriate slot, ensuring that it is pushed fully back on to the rear terminal blocks. Refit the front panel using the reverse procedure to that given in section 8.3.2. After refitting and closing the access covers on case sizes 60TE, press at the location of the hinge-assistance T-pieces so that they click back into the front panel moulding. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 35 Figure 11 Typical Opto Board Once the relay has been reassembled after repair, it should be recommissioned in accordance with the instructions in sections 1 to 7 inclusive of this chapter. 8.4 Recalibration Recalibration is not usually required when a PCB is replaced unless it happens to be one of the two boards in the input module, the replacement of which directly affect the calibration. Although it is possible to carry out recalibration on site, this requires test equipment with suitable accuracy and a special calibration program to run on a PC. It is therefore recommended that the work is carried out by the manufacturer, or entrusted to an approved service centre. 8.5 Changing the battery Each relay has a battery to maintain status data and the correct time when the auxiliary supply voltage fails. The data maintained include event, fault and disturbance records and the thermal state at the time of failure. This battery will periodically need changing, although an alarm will be given as part of the relay’s continuous self-monitoring in the event of a low battery condition. If the battery-backed facilities are not required to be maintained during an interruption of the auxiliary supply, the steps below can be followed to remove the battery, but do not replace with a new battery. 8.5.1 Instructions for Replacing The Battery Open the bottom access cover on the front of the relay. Gently extract the battery from its socket. If necessary, use a small screwdriver to prize the battery free. OPERATION GUIDE DISTANCE PROTECTION RELAYS MiCOM P441, P442 & P444 OG 1.1671-B Volume 2 Chapter 3 Page 36 Ensure that the metal terminals in the battery socket are free from corrosion, grease and dust. The replacement battery should be removed from its packaging and placed into the battery holder, taking care to ensure that the polarity markings on the battery agree with those adjacent to the socket. ! 8.5.2 Note: Only use a type ½AA Lithium battery with a nominal voltage of 3.6V. Ensure that the battery is securely held in its socket and that the battery terminals are making good contact with the metal terminals of the socket. Close the bottom access cover. Post Modification Tests To ensure that the replacement battery will maintain the time and status data if the auxiliary supply fails, check cell [0806: DATE and TIME, Battery Status] reads ‘Healthy’. 8.5.3 Battery Disposal The battery that has been removed should be disposed of in accordance with the disposal procedure for Lithium batteries in the country in which the relay is installed.
