Firmware and Manual Versions
Firmware
➤ Added calculated phase-to-phase voltages for wye-connected PTs to
the analog quantities to allow selection for display points.
➤ Implemented improved diagnostics and actions in the relay self-tests.
For certain failures, the relay will automatically restart as many as three
times.
➤ Corrected issue with Inverse Time Overcurrent elements (did not
accumulate time correctly at off-nominal frequency).
SEL-787-R203-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 the 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.

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.
