Synchro check logic
Operating modes
The closing check for automatic reclosing is possible in one of the following operating modes:
AR SYNC-CHECK
Released at synchronism, that is when the critical
values AR maxVolt.Diff, AR maxFreq.Diff, AR
maxAngleDiff are within the set limits.
AR Usy1<Usy2>
Released if measuring point Usy1< is de-energized
and the measuring point Usy2> is energized.
AR Usy1>Usy2<
Released if measuring point Usy1> is energized and
the measuring point Usy2< is de-energized.
AR Usy1<Usy2<
Released if measuring point Usy1< is de-energized
and the measuring point Usy2< is also de-energized.
AR OVERRIDE
Released without any check.
The closing check for manual reclosing is possible in one of the following operating modes:
