7.1.3 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. The energy is calculated
from the measured input currents as a sum of I
y
t values. Alarms are generated
when the calculated values exceed the threshold settings.
The function contains a blocking functionality. It is possible to block the function
outputs, if desired.
