information indicates which cycle will be run next. For example, external protection
functions can use this information to release accelerated or overreaching trip stages
prior to the corresponding reclose cycle.
“$5LVEORFNHG” (F.No. )
The automatic reclosure is blocked (e.g. circuit-breaker not ready). This information
indicates to the operational information system that in the event of an upcoming
system fault there will be a final trip, i.e. without reclosure. If the automatic reclosure
is already started, this information does not appear.
“$5QRWUHDG\” (F.No. )
The automatic reclosure is not ready for reclosure at the moment. In addition to the
“$5LVEORFNHG” (F.No. ) mentioned above there are also obstructions during
the course of the reclose cycles such as “action time expired” or “last reclaim time
running”. This information is particularly helpful during testing because no protection
test cycle with reclosure may be initiated during this state.
“$5LQSURJUHVV” (F.No. )
This information appears following starting of the automatic reclosure function, i.e.
with the first trip command that can start the automatic reclosure function. If this
reclosure was successful (or any in the case of more than one), this information
resets with the expiry of the last reclaim time. If no reclosure was successful or if
reclosure was blocked, it ends with the last — the final — trip command.
“$56\QF5HTXHVW” (F.No. )
Request for sync check measurement to an external device. This information appears
at the end of a dead time after a three-pole trip if a synchro–check request was set for
the corresponding cycle. Reclosure only takes place when the synchro–check device
has granted release “!6\QFUHOHDVH” (F.No. ).
“!6\QFUHOHDVH” (F.No. )
Release of reclosure by an external synchro–check device if this was requested by the
output information “$56\QF5HTXHVW” (F.No. ).
