11.1.6 Operation principle
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
