Application

All trip signals from GOOSE signals are routed through the trip logic. The most
simplified application of the logic function is linking the trip signal and ensuring
that the signal is long enough.
The tripping logic in the merging unit is intended to be used in the three-phase
tripping for all fault types (3ph operating). To prevent the closing of a circuit breaker
after a trip, TRPPTRC can block the CBXCBR closing.
TRPPTRC is intended to be connected to one trip coil of the corresponding circuit
breaker. If tripping is needed for another trip coil or another circuit breaker which
needs, for example, different trip pulse time, another trip logic function can be
used. The two instances of the PTRC function are identical, only the names of the
functions, TRPPTRC1 and TRPPTRC2, are different. Therefore, even if all references
are made only to TRPPTRC1, they also apply to TRPPTRC2.
The inputs from the GOOSE signal are connected to the OPERATE input. The TRIP
output is connected to the binary outputs on the IO board. This signal can also be
used for other purposes within the merging unit, for example when starting the
breaker failure protection.
TRPPTRC is used for simple three-phase tripping applications.
