Signal Description
11105_External TRIP
Tripping
command received from another protection device
(including one in the remote station) and used for the REB500
tripping contact to trip faults on a line or a power transformer.
11110_External TRIP BB
zone
Used when an external signal has to trip the entire
bus zone to which
the feeder is connected (e.g. for an external BFP signal). Applied to
all the bay units of the bus zone and sections of busbars
interconnected by an isolator (intertripping).
11115_Ext_Test_TRIP
Activates the signal 21120_EXT_TEST_TRIP
to operate several
tripping relays simultaneously.
11120_BP External TRIP
Tripping signal generated by the feeder protection part. Trips faults
on a line or power transformer with the aid of the REB500 tripping
contact. Tripping thus takes account of the busbar configuration at
the time.
To function correctly, the signal has to be assigned to a feeder. The
simplest arrangement corresponds to the assignment of the signal
11105_Ext. TRIP to feeders. If signal 11105_Ext. TRIP is not
available, a binary output has to be configured for 11120_BP
External TRIP which is then assigned to a feeder. The signal is
activated by the feeder protection directly and does not therefore
appear as binary input signal.
11125_BP External TRIP BB
zone
This is a tripping signal g
enerated by the feeder protection part which
is used to trip the entire bus zone to which the feeder is connected.
The tripping command is applied to all the bay units of the bus zone
and sections of busbars interconnected by an isolator (intertripping).
