1Ph/2Ph/3Ph Operating Mode - ABB Relion 670 Series Commissioning Manual

Section 11
Testing functionality by secondary injection
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-earth fault in one
of the remaining phases within the time interval, shorter than
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 the first fault. No other outputs should be active. Functional
outputs TRIP, all TRLn and TR3P should be active during second fault.

1ph/2ph/3ph operating mode

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
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
172
No other outputs should be active.
AutoLock and TripLockout are both set to Off .
