11.12.1.3 1ph/2ph/3ph operating mode
SEMOD54375-143 v5
In addition to other tests, the following tests, which depend on the complete
configuration of an IED, should be carried out.
Procedure
1. Make sure that AutoLock
and TripLockout are both set to Off.
2. Initiate different single-phase-to-earth faults one at a time.
Take an adequate time interval between faults into consideration, to overcome
a reclaim time, which is activated by the autorecloser function SMBRREC.
Only a single-phase trip should occur for each separate fault and only one of
the trip outputs (TRLn) should be activated at a time. Functional outputs
TRIP and TR1P should be active at each fault. No other outputs should be
active.
3. Initiate different phase-to-phase faults one at a time.
Take an adequate time interval between faults into consideration, to overcome
a reclaim time which is activated by SMBRREC. Only a two-phase trip
should occur for each separate fault and only corresponding two trip outputs
(TRLn) should be activated at a time. Functional outputs TRIP and TR2P
should be active at each fault. No other outputs should be active.
4. Initiate a three-phase fault.
Take an adequate time interval between faults into consideration, to overcome
a reclaim time, which may be activated by SMBRREC. Only a three-phase
trip should occur for the fault and all trip outputs (TRLn) should be activated
at the same time. Functional outputs TRIP and TR3P should be active at each
fault. No other outputs should be active.
5. Initiate a single phase-to-earth fault and switch it off immediately when the
trip signal is issued for the corresponding phase. Initiate the same fault once
again within the reclaim time of the used SMBRREC.
A single-phase fault shall be given at the first fault. A three-phase trip must
be initiated for the second fault. Check that the corresponding trip signals
appear after both faults. 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.
6. Initiate a single phase-to-earth fault and switch it off immediately when the
trip signal is generated for the corresponding phase. Initiate the second single-
phase-to-earth fault in one of the remaining phases within the time interval,
shorter than tEvolvingFault (default 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-
