3 FW 5.03 Release details In the following enhancement descriptions, a revision category letter is placed to the left of the description. Refer to the Appendix at the end of this document for a description of the categories displayed. L90 Enhancements H An enhancement to two terminal applications with redundant inter-relay communications that prevents the 87L element from being block when there is a channel failure in only one communication channel Applicable: L90 This firmware version ensures that, for two terminals-redundant channel schemes, the Line Current Differential Element will not be blocked when having a channel ID fail in one inter-relay communication channel only. The enhanced 87L element will be blocked when detecting channel ID fail on both interrelay communication channels. Common Protection Elements F An enhanced Restricted Ground Fault element ensures correct operation when phase current are > 13*CT Applicable: T60, G30, G60 The Restricted Ground Fault element was enhanced to ensure the relay will operate correctly when currents incoming from phase CTs are higher than thirteen times the nominal CT current (13*CT). Communications E Enhanced IEC61850 GOOSE messages prevent unwanted alarms Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60. Now GOOSE messaging has a dynamic algorithm to estimate time to live period, which prevents the generation of unnecessary Remote device off Alarms. Previous firmware version could raise this alarm when communication channels and remote devices were linked. E Faster Data File Transmission Applicable: B30, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. UR Relays now use the TFTP ports to transmit data files reducing the transmission time. E.g. event records, oscillography, fault reports, data logger. Fault Report R Improved Fault Report guarantee accurate fault records. Applicable: B30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, T35, T60. GE Multilin 3

4 UR fault report algorithm has been improved to ensure accurate fault records. In previous firmware versions, parameters like fault type, fault location and fault voltages could be inconsistent, especially in those cases where VTs were in Delta configuration and new fault records were substituting old records in memory. Real Time Clock B Improved IRIG-B noise immunity. Applicable: B30, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. IRIG-B inputs were enhanced to reduce noise sensitivity by rejecting short duration input pulses (lower than 250micro-sec). In previous firmware version, on the condition that a DC Shift IRIG-B signal had been set and a high frequency noise came in through IRIG-B inputs, the relay could reboot. Flex-Elements M Flex-elements to ensure accurate actual values when inputs are assigned to analog parameters that have a decimal point in the CT or VT ratio setting. Applicable: B30, B90, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60. UR Flex-elements were enhanced to show exact Flex-element s actual values when their analog inputs, InputPlus or InputMinus, are assigned to parameters that have a decimal point in their scale factor. E.g. voltage values which VT ratio contains decimals such as VT 6900V: 120V = 57,5:1), frequency values. Front Panel D Ensuring programmable push buttons reset when keeping them pressed for a period longer than the Auto Reset Delay setting Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60. Internal control algorithm of programmable push buttons was improved to guarantee that they would reset properly even if were kept pressed for a period longer than its Auto Reset Delay setting. It only applies providing that the Auto Reset Function be set as enable. 4 GE Multilin

5 FW 5.02 Release details In the following enhancement descriptions, a revision category letter is placed to the left of the description. Refer to the Appendix at the end of this document for a description of the categories displayed. L90 Enhancements F L90 s test functionality was enhanced to prevent unwanted operations while performing communication tests. Applicable: L90. Internal algorithms were improved so that a remote loopback test does not cause a miss-operation of the 87L element when working in a two terminals-redundant channel scheme. The previous FW versions showed up that, after experiencing both channel fail and channel ID fail alarms in one channel, the 87L element could miss operate if a remote loopback test had performed on the same failed channel. GE Multilin strongly recommends that, once the relays are in service, users must freeze (via UR Setup software) or disconnect (via hardwire) the trip contact output before performing any kind of test. F Enhanced L90 ensures correct source reading when switching settings groups and having several local sources. Applicable: L90. The L90 setting group function was improved to guarantee that all required sources are read when switching from one setting group to another one. Previous firmware version might read only the source assigned to group 1. This only applies for protections schemes were more than one local source contribute to the differential current estimation. U Enhanced two-terminal Inter relay communication ensures 87L goes back to normal after a channel fail and prevents events flooding. Applicable: L90. This firmware version ensures that, for two terminal-single channel applications, the inter-relay communication link goes back to normal once a communication failure is cleared. Previous firmware version showed that, channel fail and PFLL operands oscillated every 10 seconds when a channel fail alarm had appeared, so the 87L element didn t return to normal operation and the event recorder was flooded. L90s with firmware version prior to 4.61 are not affected by this issue. U Enhanced three-terminal Inter relay communication ensures 87L goes back to normal when Channel and PFLL alarms are reset. Applicable: L90. This firmware version ensures that, for three terminal applications, the inter-relay communication link returns to normal operation in the case that, in one terminal, both communication channels fail and then GE Multilin 5

6 just one comes back. In previous version, channel fail and PFLL operands started to oscillate, so that one communication link didn t return to normal operation. L90s with firmware version prior to 4.61 are not affected by this issue. Communications E Preventing more than 5 IEC61850 Clients from connecting to the UR. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. The IEC61850 Client/Server protocol was enhanced to prevent more than 5 clients from simultaneously connecting to the UR devices as specified in the manual. In the previous version of the firmware, if more than 5 clients attempted to simultaneously connect to a UR device, the connection to the 6th and additional clients would remain open even after communications had ceased. By having these additional connections remaining open, the overall communications to the UR would be slower than desired. In this new version of firmware, a maximum of 5 IEC61850 clients can communicate to the UR at one time and thus, all connections will open and close correctly. C Enhanced IEC61850 client/server communication prevents UR relays from losing communication when two clients are polling data. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. When two or more IEC61850 clients were linked to one UR relay, and at least one of them was polling a report (buffered or not), all clients could lose connection in the event that, the client polling the report, was disconnected from the LAN. Then the relay had to be powered off and on to recover communications. This firmware version corrects this issue. C Improved IEC prevents possible communications freezing when losing one of the masters. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. UR relays have been improved to prevent communication freezing when linked to an IEC Master. In the Previous firmware versions relay communication could freeze on the condition that the IEC60870 master dropped after about 02 days of polling message integrity. C Enhanced IEC client/server communication ensures proper interaction with 02 Siemens SICAM PAS clients. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. The IEC61850 station bus communication has been enhanced to operate correctly when two connected SICAM PAS clients are recovering from broken link. Previous firmware version could allow one of the connected UR relays to re-start when experiencing that condition. C IEC : Communicating to multiple masters properly. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. The IEC protocol was enhanced to ensure that the UR devices correctly communicate to multiple IEC masters. In the previous version of firmware, if two IEC masters were communicating to an UR device and, one of those masters were interrupted or stopped while sending requests, the UR would stop IEC communications and the UR s front panel would respond slowly when navigation buttons were pressed. When communications were disrupted due to a loss of one of the masters, all protection and control functions would continue to operate correctly. 6 GE Multilin

7 E An improved 100MB FO Ethernet port prevents communications from locking up when clearing a long period communication loss. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. The 100MB Fiber Optic Ethernet Port was enhanced to ensure that, after experiencing a long duration communication loss ( >30 minutes), the Ethernet communication goes back to normal. Relays with previous firmware version could possibly experience a lock up of the Ethernet communication. Event Recorder R Enhanced event recorder to guarantee proper sequence of Contacts inputs events when having different debounce times. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. UR event recorder was improved to ensure that all contact input events are correctly sequenced by the event recorder. Previous firmware version could allow the event recorder to miss the correct order if two contacts inputs with different debounce time settings operated almost at the same time. This issue does not affect relays with firmware version prior to Real Time Clock B Improved IRIG-B noise immunity. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. IRIG-B inputs were enhanced to reduce noise sensitivity by rejecting short duration input pulses (lower than 250micro-sec). In previous firmware version, on the condition that a DC Shift IRIG-B signal had been set and a high frequency noise came in through IRIG-B inputs, the relay could reboot. Synchrophasor M Enhanced Synchrophasor guarantee accurate Timestamp. Applicable: N60, D60, L90, G60. The continuous polling of PMU data revealed that the seconds field of synchrophasors timestamp didn t show the correct rollover from milliseconds approximately once every 45 minutes. This firmware version corrects this issue. GE Multilin 7

8 FW 5.01 Release details In the following enhancement descriptions, a revision category letter is placed to the left of the description. Refer to the Appendix at the end of this document for a description of the categories displayed. Communications C DNP3.0: Analog Values not being reported correctly Applicable: all UR-Series Relays The DNP3.0 Analog reporting has been enhanced to ensure that analog values are correctly updated and reported to the DNP master. In the previous version of firmware, the Universal Relay would meter analog values properly however, after prolonged periods of time, the analog values being reported over DNP would stop being updated and continually report the last known value. All protection and control functions continued to operate correctly when this occurred. C DNP3.0 & IEC : Ability to buffer more than 500 Binary Inputs 59 Applicable to: all UR-series relays The DNP3.0 and IEC communications in the UR has been enhanced to allow for the relay to locally buffer more than 500 Binary Input events between requests by the master for new data. In previous firmware versions, delayed requests for new Binary Inputs that can be caused by the link from the master being broken would cause the relay to not report the new events that occurred once it s buffer of 500 events was filled. C DNP3.0: Binary Counters (Object 20, 21) Responding with Incorrect Data Variation Applicable: all UR-Series Relays The DNP3.0 Binary Counters (Object 20 and 21) have been improved to respond with the correct Variation requested for by the master. In previous versions, the Binary Counters responded to requests for data in Variation 1, regardless of what Variation was requested. 8 GE Multilin

9 FW 5.00 Release details In the following enhancement descriptions, a revision category letter is placed to the left of the description. Refer to the Appendix at the end of this document for a description of the categories displayed. New features N Directional comparison unblocking (DCUB) pilot scheme is introduced on the D60 relay Applicable to: D60 relay The directional comparison unblocking (DCUB) pilot scheme has been implemented on D60 Line Distance relay for the 5.00 release. This scheme is intended for use with frequency-shift keying (FSK) narrowband power line carriers and provides excellent security against communications noise or complete signal loss. This security is achieved by continuous channel monitoring during normal channel operation, before faults, and during faults. A radio frequency (RF) signal is transmitted continuously in one of two modes: Block (also known as Guard) and Unblock (also known as Trip). During normal system operation, a Block signal is continuously being transmitted, permanently blocking all remote peers. During an internal fault, the relays are shifting the Block signal to Unblock to permit the relays to trip. When Block signal disappears during normal operation, the scheme is instantaneously blocked and returned to service only after the Block signal is re-established for specified amount of time. When the Block is lost during a fault without shifting to Unblock, the scheme is allowed to produce a trip (for a typical time of 150 ms, based on local determination of the fault only). This is based on the assumption that pilot channel loss is caused by the fault. The directional comparison unblocking (DCUB) scheme uses distance elements and optional ground directional elements to detect a fault on the line. The element is enhanced with current reversal logic, an echo feature for weak-infeed applications, and is available for three-pole and single-pole tripping applications with capability to employ up to four pilot bits. N Time offsets: time offsets (time zone and daylight savings time) added to relays Applicable to: all UR-series relays The 5.00 release introduces new settings and functionality to allows UR-series relays to determine their local time offset from Universal Time (UTC). The SNTP protocol provides UTC time synchronization. The new time zone and daylight savings time (DST) settings allow the relay to offset its clock to its own local time. The IRIG-B function provides local time. When IRIG-B is in use, the DST settings are ignored. The time zone offset setting and UTC time are used to calculate the IEC protocol timestamps, which are required to be UTC. N Wattmetric ground fault protection: new function implemented for 5.00 release Applicable to: D60, F60, L60, and L90 relays A sensitive wattmetric zero-sequence directional function can be used on isolated or resonant (Petersen coil) grounded, low-resistance grounded and solidly grounded systems to detect ground faults. The GE Multilin 9

10 function determines the presence and direction of ground faults by measuring the value and direction of zero-sequence power. The element responds to power derived from zero-sequence voltage and current in a direction specified by the element characteristic angle. The angle can be set within all four quadrants, and the power can be selected as active, reactive, or apparent. Therefore, the element may be used to sense either forward or reverse ground faults in inductive, capacitive, or resistive networks. An inverse time characteristic allows time coordination of the elements across the network. The time delay characteristic can be definite time, inverse time, or any timing curve programmed with FlexCurves. There are two elements available in the relay. Modified features E Autoreclose: changes to the 1P/3P autoreclose element Applicable to: C60, D60, L60, and L90 relays The following changes were implemented for the autoreclose function: 1. Pause functionality: Prior to this change, if the autoreclose element was paused for a time longer than the incomplete sequence timer setting, then autoreclose was locking out. The autoreclose logic has been changed to pause the reclose cycle as well as the incomplete sequence timer, thus allowing pausing for times longer than the incomplete sequence timer alone. Moreover, in earlier revisions, the autoreclose element would always resume with the AR 3P DEAD TIME 2 timer when the pause terminated. With the 5.00 release, the autoreclose logic has changed so that if the AR 3P DEAD TIME 1 timer has not timed out when the pause started, then autoreclose will resume with the AR 3P DEAD TIME 1 timer. 2. Bus Faults with breaker-and-a-half configuration: In earlier revisions, the autoreclose element did not operate for a bus or other fault in an adjacent zone that resulted in the opening of only one breaker, due to a logic requirement that both breakers have to be opened. With the 5.00 release, the implemented change now allows the autoreclose element to reclose if only one of the two breakers opens and the FlexLogic operand assigned to the AR BUS FLT INIT setting is asserted. Otherwise, two breakers must be open as per the earlier revisions. The new AR BUS FLT INIT setting is used to assign a FlexLogic operand to indicate that a trip occurred due to a bus or other fault in an adjacent zone. It is used in breaker-and-a-half applications to allow the autoreclose function to perform reclosing with one breaker open only as a result of previous bus protection operation. For line faults, both breakers still must be open for the autoreclose reclosing cycle to be performed. 10 GE Multilin

11 C Communications: all timestamps for IEC logical nodes GGIO1 and GGIO2 are now updated Applicability: all UR-series relays In earlier revisions, the timestamps for the IEC data items Mod, Beh, and Health in the GGIO1 and GGIO2 logical nodes were not updated on the occurrence of state changes. With the 5.00 release, the timestamps are now updated as required. G Communications: change in logic for primary and secondary Ethernet self-tests for 100 MB hardware and FEFI disabled Applicability: all UR-series relays The UR-series 100 megabit Ethernet hardware differs from the 10 megabit Ethernet hardware. The primary and secondary Ethernet self test logic was changed to reflect the different capability of the 100 megabit hardware. When both primary and secondary channels are disconnected, both the primary and secondary Ethernet selftests are level triggered and active. When either the primary or secondary channel is connected, the self-tests are edge triggered (that is, a failure indication occurs on channel switchover). This prevents incorrect self test indications. Also, the FEFI feature of the physical Ethernet chip was disabled. C Communications: configurable GOOSE functionality added to IEC protocol features Applicability: all UR-series relays The IEC GOOSE support in the UR-series was enhanced to include user configurable datasets. This allows the relay to interoperate with IEC devices from other manufacturers. Multiple dataset for transmission and reception are now supported. Other changes and additions include: Logical device name setting improvements, Addition of the PDIF logical node for the T60 relay, Allowing simultaneous reception of GSSE and GOOSE, Addition of a setting for LPHD location, Addition of settings for report control configuration parameters, and Addition of new settings for GGIO1 FlexLogic operands (FlexState settings are no longer used). R Event recorder: problem with system time reset at power on resolved Applicable to: all UR-series relays In earlier revisions, a remote chance existed that the UR-series system time could revert to January 1, 1970, 12:00AM after a power off/on event. This could happen in relays with a real time clock chip on the CPU board and at least one transducer input/output card in the chassis. This has been resolved for the 5.00 release. E Fault location: enhancements to the fault locator feature Applicable to: C60, D30, D60, F35, F60, L60, and L90 relays In earlier revisions of the UR-series relay, the fault locator was unable to measure the distance to the ground fault correctly if the voltage to the relay was supplied from the delta-connected VTs. This occurred because zero sequence voltages were not available for correct calculations. GE Multilin 11

12 The 5.00 release allows the fault locator to locate ground faults by using either the zero-sequence voltage supplied from broken-delta VTs or by approximating the zero-sequence voltage from zero-sequence current and equivalent zero-sequence impedance sources behind the relay. In additions, the fault type selection was improved for the D60, L60, and L90 line relays. The following new settings have been added for the 5.00 release: FAULT REP 1 VT SUBSTITUTION: specifies whether the zero-sequence voltage is measured from wyeconnected VTs (none), supplied from broken-delta VT connected to fourth VT input (V0), or approximated from the zero sequence current and source impedance (I0). FAULT REP 1 SYSTEM Z0 MAG and FAULT REPORT 1 SYSTEM Z0 ANGLE: these settings are used only when the FAULT REP 1 VT SUBSTITUTION setting is set to I0. The magnitude entered is in secondary ohms and is based on average system zero-sequence equivalent impedance behind the relay. D FlexElements : the FlexElement value for df/dt has been corrected Applicable to: F60, G30, G60, and N60 relays In previous revisions, the actual value displayed would be incorrect when the frequency rate of change (df/dt) was used as an input FlexAnalog value for FlexElements. This has been fixed for the 5.00 release R High impedance fault detection: modifications to high-impedance fault detection sequence of events Applicable to: F60 relay Modifications to the sequence of events recording have been made to allow the user to apply a chatter filter to the generation of the high-impedance fault detection arcing detected event. Additional FlexLogic operands have been added for determination of the armed/disarmed status of the highimpedance fault detection algorithm. Please refer to the instruction manual for additional details. G Internal enhancement: incorrect timestamp strings corrected Applicability: all UR-series relays In previous revisions, internal system functionality may have caused incorrect timestamp strings to be created. Any problems caused by this were likely to be extremely intermittent. This has been corrected for the 5.00 release. D L90 power system: undefined message in L90 power system menu removed Applicable to: L90 relay In previous revisions, the UNDEFINED message would appear when pressing the message right key while the CHARGING CURRENT COMPENSATION setpoint was displayed on the front panel. This message has been removed for the 5.00 release. E Pilot schemes: block setting added to all D60 pilot schemes Applicable to: D60 relay A block setting has been added to all five D60 pilot schemes for the 5.00 release. This setting is typically required to take the pilot scheme out of service, either locally using a panel cut-off switch or remotely via 12 GE Multilin

13 software. When the pilot scheme is blocked, scheme operation is inhibited as well as the transmittal of the pilot bits to remote peers. M Synchrocheck: additional resolution on the Synchrocheck element Applicable to: C60, D30, D60, F60, G30, G60, L60, L90, and N60 relays Additional resolution has been added to the measured frequency quantity used when evaluating the operational condition of the synchrocheck element. This allows for finer adjustment when comparing two input frequency values. R Synchrophasors: erasing phase measurement unit (PMU) record now erases all records Applicable to: N60, D60, L90, G60. In previous revisions, the first phase measurement unit (PMU) record PMU000.* would not erase when attempting to erase all records. With the 5.00 release, the first record is now labeled as PMU001.* and will erase when required. D Synchrophasors: new selection added for phase measurement unit (PMU) communication port type Applicable to: N60, D60, L90, G60. The None selection has been added for the phase measurement unit (PMU) communications port type setting. C Synchrophasors: phase measurement unit (PMU) data transmission now disables correctly Applicable to: N60, D60, L90, G60. For the 5.00 release, the PMU disable data transmit command has been changed so it only turns off the transmission of data frames. In earlier revisions, the command disabled the transmission of configuration frames as well as header frames. R Synchrophasors: phase measurement unit records now available in binary format Applicable to: N60, D60, L90, G60. The phase measurement unit (PMU) records are now supported in binary format. The file naming convention is as follows: Binary format: PMU###.dat ASCII format: PMU###A.dat Where ### is a sequential filename; for example, PMU012.dat. Due to the extensive on-board memory allocated for PMU recording, the file size of a PMU record in ASCII format can be very large. As such, it is recommended to retrieve PMU files in binary format. If the number of PMU records is only 1, it has been noted during testing that retrieval of large files via TFTP in ASCII format can cause the TFTP client to timeout. On some occasions, repeated failed attempts to retrieve the large file may cause the N60 to restart. Ensuring that the PMU recorder is configured to create a minimum of two files alleviates this issue. GE Multilin 13

14 E System setup: phase sequence reversal setting UR revision 5.03 release notes Applicable to: G30 and G60 relays This new setting allows the phase sequence expected by the relay to be dynamically reversed based on the state of a FlexLogic operand. For example, if the nominal phase rotation setting is ABC but the condition defined for opposite phase rotation is true, then the expected phase rotation will switch to ACB. This feature is only intended for use in special applications, such as pumped storage schemes. E User-programmable pushbuttons: enhancements to user-programmable pushbutton operation Applicable to: all UR-series relays The UR-series user-programmable pushbuttons were enhanced to provide remote control capability of pushbuttons in parallel with control from the faceplate. This provides a single output to control station equipment from both the front panel interface and remote controls with capability of interlocking between local and remote controls. The following new settings have been added: PUSHBUTTON 1(12) SET: assigns a FlexLogic operand to operate pushbutton 1(12) and assert the PB 1(12) ON FlexLogic operand. PUSHBTN 1(12) RESET: assigns a FlexLogic operand to reset pushbutton 1(12) and assert PB 1(12) OFF FlexLogic operand. PUSHBTN 1(12) AUTORESET: enables automatic reset of pushbutton 1(12). PUSHBTN 1(12) AUTORESET DELAY: specifies the delay for automatic reset of pushbutton 1(12). PUSHBTN 1(12) REMOTE LOCK: assigns a FlexLogic operand to lock out remote control for pushbutton 1(12). PUSHBTN 1(12) LOCAL LOCK: assigns a FlexLogic operand to lock out faceplate control for pushbutton 1(12). PUSHBTN 1(12) DROP-OUT TIME: specifies the dwelling time of the PB 1(12) ON operand in self-reset mode. PUSHBTN 1(12) LED CONTROL: specifies the FlexLogic operand driving corresponding pushbutton LED. The PUSHBTN 1(12) TARGETS setting was changed to read PUSHBUTTON 1(12) MESSAGE. This setting defines the priority of the pushbutton targets. 14 GE Multilin

15 Upgrade paths It is our recommendation that all customers upgrade to the latest version of UR-series firmware to take advantage of the latest developments and feature enhancements. Firmware upgrades can be easily preformed using the EnerVista UR Setup software. This software can also convert settings files from an older version to the latest version and provides a Difference Report once the conversion has been completed. This Difference Report identifies new settings and additional information to assist the user during the upgrade. Upgrade path for versions 4.00 and above For UR-series devices installed with versions 4.00 firmware and above, the revision 5.60 release can be uploaded to the relay using the EnerVista UR Setup software. Upgrade path for revisions below version 4.00 For UR-series devices installed with versions of firmware below 4.00, an upgrade package must be obtained from GE Multilin to upgrade the relay CPU and CT/VT modules. Benefits of revision 4.00 and above: The benefits of revision 4.00 and above are as follows: Supports many new features and functionality IEC communications protocol 100 Mb Ethernet IRIG-B repeater Isolated RS485 and IRIG-B Synchrophasors in the D60, L90, N60 & G60 Support for Breaker-and-a-Half Transmission Line Protection (D60, L90) Motor Health Diagnostics (M60) Enhanced Front Panel Exceeds new IEEE C37.90 requirements - Transient immunity (2 to 4 kv) GE Multilin 15
