Cyclic Reclosing Function: Logic for the reclaim time
Circuit-Breaker Readiness and Circuit-Breaker Condition
The automatic reclosing function requires the readiness of the circuit breaker for the following purposes, see
Figure 7-49:
•
Recognition of the circuit-breaker readiness from the beginning:
In idle state of the automatic reclosing function, an unavailable circuit breaker leads to the blocking of
the automatic reclosing function. This monitoring is optional and must be switched off through settings if
the readiness signal is not available for the protection device.
•
Analysis of the circuit-breaker readiness directly before the close command:
For each of the configured automatic reclosing cycles, it can be set whether the circuit-breaker readiness
is a requirement for the assignment of the close command. This monitoring is also optional.
