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 their original values, if they were changed for
testing purposes.
Integrator TIGAPC
The integrator function TIGAPC can be tested by connecting a binary signal to the
input of the function and applying pulses to the function. Normally the Integrator will
be tested when testing the function the integrator is connected to, such as reverse
power, loss of excitation and pole slip. When the function is configured, test it together
with the function that operates it.
Completing the test
Continue to test another function or end the test by changing the Test mode setting to
Off. Restore connections and settings to their original values, if they were changed for
testing purposes.
