tested together with the autorecloser function, when built into the IED or when a separate external unit is
used for reclosing purposes.

11.12.1.2 Three-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.
11.12.1.3 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.

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.
