Functions
2.2 Automatic reclosure function (optional)
„AR is blocked" (No. 2783)
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 has been started, this information does not appear.
„AR not ready" (No. 2784)
The automatic reclosure is not ready for reclosure at the moment. In addition to the „AR is blocked" (No.
2783) mentioned above there are also obstructions during the course of the auto-reclosure cycles such as
„action time run out" 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.
„AR in progress" (No. 2801)
This information appears with starting of the automatic reclosure function, i.e. with the first trip command which
can start the automatic reclosure. If this reclosure was successful (or any in the case of multiple cycles), this
information resets with the expiry of the last blocking time. If no reclosure was successful or if reclosure was
blocked, it ends with the last – the final – trip command.
„AR Sync.Request" (No. 2865)
Measuring request to an external synchronism check device. The information appears at the end of a dead time
subsequent to three-pole tripping if a synchronism request was parameterised for the corresponding cycle. Re-
closure only takes place when the synchronism check device has provided release signal „>Sync.release"
(No. 2731).
„>Sync.release" (No. 2731)
Release of reclosure by an external synchronism check device if this was requested by the output information
„AR Sync.Request" (No. 2865).
