Completing the test

Continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.
12.10.4

Single command, 16 signals SINGLECMD

For the single command function block, it is necessary to configure the output signal to
corresponding binary output of the IED. The operation of the single command function
(SINGLECMD) is then checked from the local HMI by applying the commands with
Steady or Pulse , and by observing the logic statuses of the corresponding binary output.
Command control functions included in the operation of different built-in functions must be
tested at the same time as their corresponding functions.
12.10.5

Interlocking

Prepare the IED for verification of settings as outlined in section
section
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

12.11.1

Tripping logic, common 3-phase output SMPPTRC

Prepare the IED for verification of settings as outlined in section
section
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.
12.11.1.1

Three-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.
