If stage U0>> has started and the residual voltage falls below the set start value of
the stage, the start of the stage remains active for 100 ms. If the residual voltage
exceeds the set start value again while the timer is running, the timer is cleared and
the start of the stage remains active. If stage U0>> has already tripped, the stage is
reset in 50 ms after the residual voltage falls below 0.5 times the set start value of
the stage. However, if stage U0>> has already tripped and the residual voltage has
fallen below the set start value of the stage, but not below 0.5 times the set start
value, the stage is reset after the 100 ms’ resetting time has expired.
Stage U0> can be set out of operation in SGF3/3 and stage U0>> can be set out of
operation in SGF3/4. This state is indicated by dashes on the LCD and by 999
when the set start value is read via serial communication.
It is possible to block the tripping of a residual overvoltage stage by
applying a digital input signal to the relay.
5.1.4.5. Circuit-breaker failure protection
The circuit-breaker failure protection (CBFP) detects situations where the trip
remains active although the circuit breaker should have operated.
The CBFP unit generates a trip signal via output PO2 when the set operate time of
CBFP expires.
The CBFP can be triggered internally via protection functions. All the signals,
except external trip, routed to output PO1 trigger the CBFP. If the fault situation is
not cleared when the set operate time has elapsed, the CBFP generates a trip signal
via output PO2.
The CBFP can also be selected to be triggered externally by applying a digital input
signal to the relay, if the maximum of all three phase-to-phase voltages is above 0.15
× Un. If the fault situation is not cleared when the set operate time has elapsed, the
CBFP generates a trip signal via output PO2.
Internal triggering is selected by activating the CBFP in SGF1/6 and external
triggering by activating the CBFP in SGB1...5/7.
Normally, the CBFP controls the upstream circuit breaker. However, it can also be
used for tripping via redundant trip circuits of the same circuit breaker.
