setting 2.0s) and shorter than the dead-time of SMBRREC, when included in the
protection scheme.
Check that the second trip is a three-phase trip and that a three-phase autoreclosing
attempt is given after the three-phase dead time. Functional outputs TRIP, TRLn and
TR1P should be 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 than
2.0s).
Check, that the output signals, issued for the first fault, correspond to a two- 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
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
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
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
