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
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.

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-ground faults one at a time.
Take an adequate time interval between faults into consideration, to overcome a reset time,
which is activated by the autorecloser function SMBRREC (79). Only a single-pole trip should
occur for each separate fault and only one of the trip outputs (TR_A, TR_B, TR_C) 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 reset time
which is activated by SMBRREC (79). Only a two-phase trip should occur for each separate
fault and only corresponding two trip outputs (TR_A, TR_B, TR_C) 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.
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 same fault once again within the reset time
of the used SMBRREC (79).
A single-phase fault shall be given at the first fault. A three-pole trip must be initiated for the
second fault. Check that the corresponding trip signals appear after both faults. Functional
outputs TRIP, TR_A, TR_B, TR_C and TR1P should be active during 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.
6. Initiate a single phase-to-ground fault and switch it off immediately when the trip signal is
generated for the corresponding phase. Initiate the second single-phase-to-ground fault in
one of the remaining phases within the time interval, shorter than
