Three overvoltage and undervoltage protection stages (PHxPTOV and PHxPTUV)
offer protection against abnormal phase voltage conditions. The operation of
voltage functions is connected to alarm LED 3. A failure in the voltage measuring
circuit is detected by the fuse failure function and the activation is connected to
undervoltage protection functions to avoid faulty undervoltage tripping.

Figure 90: Residual overvoltage protection
The residual overvoltage protection (ROVPTOV) provides earth-fault protection
by detecting abnormal level of residual voltage. It can be used, for example, as a nonselective backup protection for the selective directional earth-fault functionality.
The operation signal is connected to alarm LED 2.

All start and operate signals from the protection stages are routed either to trigger
the disturbance recorder or to be recorded by the disturbance recorder, depending
on the parameter settings. Additionally, the selected autorecloser, the ARC
protection signals, the synchrocheck signals and the three binary inputs from X120
are also connected.

Figure 93: Trip circuit supervision
Two separate trip circuit supervision functions are included, TCSSCBR1 for PO3
(X100:15-19) and TCSSCBR2 for PO4 (X100:20-24). Both functions are blocked
by the Master Trip (TRPPTRC1 and TRPPTRC2) and the circuit breaker open
signal. The TCS alarm indication is connected to LED 9.
By default it is expected that there is no external resistor in the
circuit breaker tripping coil circuit connected parallel with circuit
breaker normally open auxiliary contact.
The fuse failure supervision SEQRFUF1 detects failures in voltage measurement
circuits. Failures, such as an open miniature circuit breaker, are detected and the
alarm is connected to the alarm LED 9.
Failures in current measuring circuits are detected by CCRDIF. When a failure is
detected, blocking signal is activated in current protection functions that are
measuring calculated sequence component currents, and unnecessary operation can
be avoided. The alarm signal is connected to the alarm LED 9
