Testing functionality by secondary injection
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.

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.
No other outputs should be active.
4. 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.
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 second single phase-to-
