active during first fault. No other outputs should be active. Functional outputs TRIP, all TRLn
and TR3P should be active during second fault.
7. Initiate a phase-to-phase fault and switch it off immediately when the trip signal is issued for the
corresponding two phases. Initiate a second phase-to-phase fault between two other phases
within the time interval, shorter thantEvolvingFault (default setting 2.0s).
Check, that the output signals, issued for the first fault, correspond to a two-phase trip for
included phases. The output signals generated by the second fault must correspond to the
three-phase tripping action.

Circuit breaker lockout

The following tests should be carried out when the built-in lockout function is used in addition to
possible other tests, which depends on the complete configuration of an IED.
1. Check that AutoLock and TripLockout are both set to Off.
2. Activate shortly the set lockout (SETLKOUT) signal in the IED.
3. Check that the circuit breaker lockout (CLLKOUT) signal is set.
4. Activate shortly thereafter, the reset lockout (RSTLKOUT) signal in the IED.
5. Check that the circuit breaker lockout (CLLKOUT) signal is reset.
6. Initiate a three-phase fault.
A three-phase trip should occur and all trip outputs TRL1, TRL2, TRL3 should be activated.
Functional outputs TRIP and TR3P should be active at each fault. The output CLLKOUT should
not be set.
7. Activate the automatic lockout function, set AutoLock = On and repeat.
Besides the TRIP outputs, CLLKOUT should be set.
8. Reset the lockout signal by activating the reset lockout (RSTLKOUT) signal.
9. Activate the trip signal lockout function, set TripLockout = On and repeat.
All trip outputs (TRL1, TRL2, TRL3) and functional outputs TRIP and TR3P must be active and
stay active after each fault, CLLKOUT should be set.
10. Reset the lockout.
All functional outputs should reset.
11. Deactivate the trip signal lockout function, set TripLockout = Off and the automatic lockout
function, set AutoLock = Off.

Completing the test

Continue to test another function or end the test by changing the TESTMODE setting to Off. Restore
connections and settings to the original values, if changed for testing purposes.

Monitoring

11.13.1

Gas medium supervision SSIMG

Prepare the IED for verification of settings as outlined in Section
in this chapter.
Values of logical signals for SSIMG protection are available on the local HMI under Main menu /
Test /Function status /Monitoring /InsulationGas /SSIMG:x , where x = 1, 2,....21.
The Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
Check that the input logical signal BLOCK is logical zero and that on the local HMI, the logical signals
PRESALM , PRESLO , TEMPALM , TEMPLO , ALARM and LOCKOUT are logical zero.
