Description
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.
Used when an external signal has to trip the entire bus zone to
which the feeder is connected (for example, an external BFP signal).
Applied to all the bay units of the bus zone and sections of busbars
interconnected by an isolator (intertripping).
Activates the signal 21120_EXT_TEST_TRIP to operate several
tripping relays simultaneously.
