Figure 2.3.24-4. Two synchrocheck stages needed with “3Side”-mode.
2.3.25. Circuit-breaker failure protection (50BF)
The operation of the circuit-breaker failure protection (CBFP)
is based on the supervision of the operating time from the
pickup of the configured trip relay to the dropout of the same
relay. If that time is longer than the operating time of the
CBFP stage, the CBFP stage activates another output relay,
which will remain activated until the primary trip relay resets.
The CBFP stage functions with all the protection functions
since it supervises the trip relay.
Setting parameters of circuit-breaker failure protection:
