SEL-787-R108-V0-Z002001-D20120921 ➤ Corrected an issue with the STA command response in R107
firmware. The relay was displaying incorrect values for the internal
power supply level on the main board.
➤ Corrected an I/O card issue in R107 firmware. Firmware was not
allowing the relay to accept an I/O card in an empty slot.
➤ Corrected a GPSB failure issue in R107 firmware.
20120921
SEL-787-R107-V0-Z002001-D20111107
➤ Manual update only (see Table A.6). 20120903
SEL-787-R107-V0-Z002001-D20111107
➤ Corrected an issue with the rms meter values, where in some cases the
values would spike for a short time.
➤ Corrected primary current magnitude calculation for delta-connected
CTs by dividing by square root of 3 factor in the meter and event
report delta current quantities.
20111107
SEL-787-R106-V0-Z002001-D20110201
➤ Manual update only (see Table A.6). 20110610
SEL-787-R106-V0-Z002001-D20110201
➤ Corrected issue with Inverse Time Overcurrent elements (did not
accumulate time correctly for FNOM = 50 Hz nominal frequency).
20110201
SEL-787-R105-V0-Z002001-D20101115
➤ Manual update only (see Table A.6.) 20101217
SEL-787-R105-V0-Z002001-D20101115
➤ Added a squelch threshold for very low-level secondary voltages
(below 0.1 V) and currents (below 1% of INOM) in the metering
quantities command response.
➤ Added calculated phase-to-phase voltages for wye-connected PTs to
the analog quantities to allow selection for display points.
➤ Corrected issue with Inverse Time Overcurrent elements (did not
accumulate time correctly at off-nominal frequency).
20101115
SEL-787-R104-V0-Z002001-D20100730
➤ Added new Winding 1 and Winding 2, level 1, Phase A, Phase B and
Phase C instantaneous overcurrent elements.
➤ Added new Winding 1 and Winding 2 Phase A, Phase B and Phase C
Time-Overcurrent elements.
➤ Updated the error messages for setting interdependency checks to
match the global setting AOx0yH.
➤ Extended CT ratio setting range to 1:10000 for 5 A CTs and 1:50000
for 1 A CTs.
➤ Enhanced REF element logic by adding 52A interlock (new setting
REF52BYP).
➤ Added capability to support two Modbus TCP sessions with timeout
settings on the Ethernet port.
➤ Added Select Before Operate control (SBO) to the IEC 61850 protocol.
➤ Added Access Control setting BLOCK MODBUS SET
(BLKMBSET) to be able to block settings changes from a remote
Modbus or DeviceNet master.
➤ Added new I/O card option of 4 DI/3 DO, which has one Form-B and
two Form-C outputs.
➤ Corrected relay status reporting via Modbus when relay is disabled.
➤ Updated Ethernet port settings IPADDR, SUBNETM, and DEFRTR
validation to allow addresses in the private address space.
➤ Added FASTOP setting to Port 1 (Ethernet) settings to allow breaker
control using Fast Operate.
➤ Added IRIG-B input capability to fiber-optic serial Port 2 option
including a new Time-Synchronization Source setting TIME_SRC.
➤ Added front-panel setting FP_AUTO to allow choice between
OVERRIDE and ROTATING display messages.
