Function description
Circuit breaker condition monitoring
13.17.2 Functionality
The circuit breaker condition monitoring function SSCBR is used to monitor different parameters
of the circuit breaker. The breaker requires maintenance when the number of operations has
reached a predefined value. For proper functioning of the circuit breaker, it is essential to monitor
the circuit breaker operation, spring charge indication, breaker wear, travel time, number of
operation cycles and accumulated energy. The energy is calculated from the measured input
currents as a sum of I
threshold settings.
The function contains a blocking functionality. It is possible to block the function outputs, if
desired.
