16.4 Breaker monitoring SSCBR
16.4.1 Identification
Function description
Breaker monitoring
16.4.2 Functionality
The breaker monitoring function SSCBR is used to monitor different parameters of the breaker
condition. The breaker requires maintenance when the number of operations reaches a predefined
value. For a proper functioning of the circuit breaker, it is essential to monitor the circuit breaker
operation, spring charge indication or breaker wear, travel time, number of operation cycles and
estimate the accumulated energy during arcing periods.
