3.3.3.2 Functional diagrams for disturbance recorder
Output signals from the condition monitoring and supervision functions are
routed to trigger the disturbance recorder or, alternatively, only to be recorded by
the disturbance recorder depending on the parameter settings. Additionally, the
selected signals from different functions are also connected to the disturbance
recorder.

3.3.3.3 Functional diagrams for condition monitoring and supervision
Failures in the current measuring circuits are detected by CCSPVC1.
The fuse failure supervision function SEQSPVC1 detects failures in the voltage
measurement circuits. Failures, such as an open MCB, raise an alarm.
