Testing functionality by secondary injection
Values of the logical signals are available on the local HMI under Main menu/Tests/
Function status/Control/Apparatus control/Interlocking. The Signal Monitoring
in PCM600 shows the same signals that are available on the local HMI.
The interlocking function consists of a bay-level part and a station-level part. The
interlocking is delivery specific and is realized by bay-to-bay communication over the
station bus. For that reason, test the function in a system, that is, either in a complete
delivery system as an acceptance test (FAT/SAT) or as parts of that system.

Logic

Tripping logic, common 3-phase output SMPPTRC

Prepare the IED for verification of settings outlined in section
section "Preparing for test"
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.
The instances of SMPPTRC are identical except for the name of the function block
SMPPTRC. The testing is preferably done in conjunction with the protection system
and autoreclosing function.

Three-phase operating mode

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.

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 TripLockout and AutoLock are both set to Off.
2. Initiate different single-phase-to-earth faults one at a time.
