Figure 240: Circuit breaker condition monitoring
Failures in current measuring circuits are detected by CCSPVC1_CCM. When a failure is
detected, it can be used to block the current protection functions that are measuring the
calculated sequence component currents or residual current to avoid unnecessary
operation.

Figure 241: Current circuit supervision function
The fuse failure supervision SEQRFUF1_60-1 and SEQRFUF2_60-2 detects failures in
voltage measurement circuits. Failures, such as an open miniature circuit breaker, are
detected and the alarm is connected to the few voltage based protection functions to avoid
misoperation.
