12.3.1 CommTrpPer
Common trip permanent relay; closes at any failure with a delay given by appropriate parameter. The relay is
kept in open position in a fault-free state and closes immediately in case of LOM protection (Vector shift or
ROCOF), External trip, incorrect phase rotation or wrong phase polarity. Relay opens in fault free state after
successful fault reset. In case of LOM protection, the delay
timed out and after this time it is possible to perform

12.3.2 !CommTrpPer
Inverse common trip permanent relay; opens at any failure with a delay given by appropriate parameter. The
relay opens immediately in case of LOM protection (Vector shift or ROCOF), External trip, incorrect phase
rotation or wrong phase polarity. Relay closes in fault free state after a successful fault reset. In case of LOM
protection, the delay

12.3.3 CommTrpImp
Common trip impulse relay; closes at any failure with a delay given by appropriate parameter. The relay is
kept in open position in a fault-free state and closes immediately in case of LOM protection (Vector shift or
ROCOF), External trip, incorrect phase rotation or wrong phase polarity. Relay opens after

has timed out, his opening however does not mean end of trip state! Trip is terminated in fault free
state after a successful fault reset. In case of LOM protection, the delay

is timed out and after this time it is possible to perform Fault reset. During trip status, the relay does
not react on any new failure.

12.3.4 !CommTrpImp
Inverse common trip impulse relay; opens at any failure with a delay given by appropriate parameter. The
relay opens immediately in case of LOM protection (Vector shift or ROCOF), External trip, incorrect phase
rotation or wrong phase polarity. Relay closes after Basic: Imp Len has timed out, his closing however does
not mean end of trip state! Trip is terminated in fault free state after a successful fault reset. In case of LOM

Immediate impulse signaling relay; closes immediately at any failure. The relay opens after
