Connection of an External Automatic Reclosing Function
There are no setting parameters for operation with external automatic reclosing functions. The function
provides exclusively the following described binary inputs. The external reclosing device can thus have an
influence on the effects of the internal protection functions.
The following connection possibilities exist:
•
From the external reclosing function, the signal
>Release stages
can be coupled so that the protec-
tion functions use special stages or zones for release. An example is the release of an overreaching zone
with a distance protection or the non-delayed tripping of an overcurrent protection stage in the 1st
reclosing cycle.
•
For applications with 1-pole tripping, the external reclosing can provide the signal
>1-pole trip
permitted
, based on which the protection functions can switch off the 1-pole circuit breaker.
•
For applications with reclosing functions only with 1-pole faults and stage or zone releases through the
reclosing function can the signal
>1-pole AR only
be connected. The protection functions use this
information to allow the stage or zone release only affect 1-pole faults.
