3 phase operating mode

1. Check that AutoLock and TripLockout are both set to Disabled .
2. Initiate a three-phase fault.
An adequate time interval between the faults should be considered, to overcome a reset time
caused by the possible activation of the autorecloser function SMBRREC (79). The function must
issue a three-pole trip in all cases when trip is initiated by any protection or some other built-in or
external function. The following functional output signals must always appear simultaneously: TRIP,
TR_A, TR_B, TR_C and TR3P.
11.10.1.3

1p/3p operating mode

In addition to various other tests, the following tests should be performed. They depend on the complete
configuration of an IED:
Procedure
1. Make sure that TripLockout and AutoLock are both set to Disabled.
2. Initiate different single-phase-to-ground faults one at a time.
3. Initiate different phase-to-phase and three-phase faults.
Consider using an adequate time interval between faults, to overcome a reset time, which is
activated by SMBRREC (79). A three-pole trip should occur for each separate fault and all of the
trips. Functional outputs TRIP, all TR_A, TR_B, TR_C and TR3P should be active at each fault.
4. Initiate a single phase-to-ground fault and switch it off immediately when the trip signal is issued for
the corresponding phase. Initiate the same fault once again within the reset time of the used
SMBRREC (79).
5. Initiate a single phase-to-ground fault and switch it off immediately when the trip signal is issued for
the corresponding phase. Initiate the second single phase-to-ground 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 (79), when included in the protection scheme.
Check that the second trip is a three-pole trip and that a three-phase autoreclosing attempt is given
after the three-phase dead time. Functional outputs TRIP, TR_A, TR_B, TR_C and TR1P should be
active during the first fault. No other outputs should be active. Functional outputs TRIP, all TR_A,
TR_B, TR_C and TR3P should be active during second fault.

2.2.3 -
2.2.4 -
2.2.4 Added TRINN (Trip neutral) input and TRN (trip neutral) outputs. TRINALL (Trip all phases)
input is changed from TRIN. IEC 61850 mapping is made for the added output. The block
logic is corrected for the lockout functionality.
2.2.5 -
No other outputs should be active.
