15.1.6 Operation principle
M12255-3 v10.1.1
The duration of a trip output signal from tripping logic common 3-phase output SMPPTRC (94) is
settable (
tTripMin ). The pulse length should be long enough to secure the breaker opening.
For three-pole tripping logic common 3-phase output, SMPPTRC (94) has a single input (TRINP_3P)
through which all trip output signals from the protection functions within the IED, or from external
protection functions via one or more of the IEDs binary inputs, are routed. It has a single trip
output (TRIP) for connection to one or more of the IEDs binary outputs, as well as to other
functions within the IED requiring this signal.
