Application

All trip signals from different protection functions 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 protection relay 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 protection functions are connected to the OPERATE input.
Usually, a logic block OR is required to combine the different function outputs to
this 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 protection relay, for example
when starting the breaker failure protection.
TRPPTRC is used for simple three-phase tripping applications.
