11.1.6 Operation principle
The duration of a trip output signal from tripping logic common 3-phase output
SMPPTRC is settable (tTripMin). The pulse length should be long enough to secure
the breaker opening.
For three-phase tripping logic common 3-phase output, SMPPTRC has a single input
(TRIN) 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.
