Description
Combined tripping command summarizes the phase L3 tripping
commands of station protection and bay protection functions (if
existing). For details about combined tripping commands see
Combined tripping command summarizes the phase L0 tripping
commands of station protection and bay protection functions (if
existing). For details about combined tripping commands see
Combined general Tripping command summarizes the remote tripping
tripping commands of station protection and bay protection functions (if
existing). For details about combined (remote) tripping commands see
Section
Signals tripping by the bay unit and can be set by any of the station
protection functions.
Signals that the station protection functions including EXTERNAL TRIP
and intertripping are blocked (either the bay concerned or throughout the
station).
All the output contacts configured in the bay unit concerned are blocked.
Signal set by the diagnostic function that shows whether or not a bay unit
is operational and standing by.
This signals a failure of the isolator auxiliary supply (Supervision aux.
voltage_x) in the bay unit.
This signal appears when an inspection or maintenance input is set in the
bay unit and a position indicator on an isolator or circuit-breaker
connected to the bay unit is forced into a particular status.
Forcing of an isolator or circuit-breaker in this context means: The item of
switchgear changes either from CLOSED to OPEN or from OPEN to
CLOSED.
Signals an alarm situation in a bay unit: if an auxiliary supply fault is being
signaled or if a bay unit diagnostic system has detected an analogue
signal processing error.

L # Description
- 1 Signals that BBP is blocked (either individual protection
zones or the entire system)
2 Trip generated by BFP (after t1)
●
- 2 Tripping command issued to the remote station by BFP.
This signal can be assigned to an output contact by the
signal REMOTE TRIP.
1 Signals tripping by BFP after time step 1

2 BFP detected a fault on phase L2 and has tripped.
●
2 BFP detected a fault on phase L3 and has tripped.
●
- 1 Tripping has been redirected, providing a signal is being
applied to the input 13605_Trip redirection _1 or
13606_Trip redirection_2.
- 1 BFP has issued an intertripping command.
