11.12.1.2

3 phase operating mode

1. Check that AutoLock and TripLockout are both set to Off .
2. Initiate a three-phase fault.
An adequate time interval between the faults should be considered, to overcome a reclaim time
caused by the possible activation of the autorecloser function SMBRREC. The function must
issue a three-phase 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, TRL1, TRL2, TRL3 and TR3P.
11.12.1.3

1ph/3ph 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 Off.
2. Initiate different single-phase-to-earth faults one at a time.
Single-phase tripping will only be allowed when an autoreclose attempt will follow. The
autorecloser function SMBRREC has the functionality such as the long trip time, CB ready and
so on, which can prevent a proper single-phase tripping and autoreclose. To by-pass this
problem the fault initiation should be with a test set and with the autoreclose in full service with
a test set connected to the distance protection function. Consider using an adequate time
interval between faults, to overcome a reclaim time of which is activated by 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 during each
fault. No other outputs should be active.
3. Initiate different phase-to-phase and three-phase faults.
Consider using an adequate time interval between faults, to overcome a reclaim time, which is
activated by SMBRREC. A three-phase trip should occur for each separate fault and all of the
trips. Functional outputs TRIP, all TRLn 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.
