Tripping logic, common 3-phase output SMPPTRC (94)

Prepare the IED for verification of settings outlined in Section
This function is functionality tested together with other protection functions (line differential protection,
ground-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.

3 phase operating mode

1. Check that AutoLock and TripLockout are both set to Disabled .
2. Initiate a three-phase fault.
An adequate time interval between the faults should be considered, to overcome a reset time
caused by the possible activation of the autorecloser function SMBRREC (79). The function must
issue a three-pole 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,
TR_A, TR_B, TR_C and TR3P.
11.12.1.3

1p/3p 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 Disabled.
2. Initiate different single-phase-to-ground faults one at a time.
3. Initiate different phase-to-phase and three-phase faults.
