Tripping logic, common 3-phase output SMPPTRC

Prepare the IED for verification of settings outlined in Section
settings".
This function is functionality tested together with other protection functions (line differential
protection, earth-fault overcurrent protection, and so on) within the IED. It is recommended
that the function is tested together with the autorecloser function, when built into the IED or
when a separate external unit is used for reclosing purposes.
11.11.1.1

3 phase operating mode

1. Check that
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.
11.11.1.2

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
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.
