The automatic reclosure is blocked (e.g. circuit breaker not ready). This information indicates to the opera-
tional 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
mentioned above (No. 2783)there are also obstructions during the course of the auto-reclosure cycles such as
“action time” elapsed 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 following the start 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
multiple cycles), the information is reset 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.
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 3-pole tripping if a synchronism request was parameterized for the corresponding cycle.
Reclosure only takes place when the synchronism check device has provided the 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).
