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.

Figure 91: Frequency protection

The selectable underfrequency or overfrequency protection (FRPFRQ) prevents

damage to network components under unwanted frequency conditions.

The function contains a selectable rate of change of the frequency (gradient)

protection to detect an increase or decrease in the fast power system frequency at

Figure 92: Disturbance recorder

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
