Testing functionality
The voltage change should be greater than set
greater than the set
The BLKU, BLKZ and 3PH signals should not appear.
6. Disconnect the dc voltage to the CBCLOSED binary input.
7. Apply normal conditions as in step 1.
8. Repeat step 3.
9. Connect the nominal voltages in all three phases and feed a current below the operate
level in all three phases.
10. Keep the current constant. Disconnect the voltage in all three phases simultaneously.
The BLKU, BLKZ and 3PH signals should not appear.

Completing the test

Continue to test another function or end the testing by setting the parameter
under Main menu/Tests/IED test mode/1:TESTMODE. If another function is tested, then set
the parameter
system supervision/SDDRFUF/1:SDDRFUF for the function, or for each individual function in a
chain, to be tested next. Remember to set the parameter
function that has been tested.

Testing logic functions

7.7.1

Tripping logic SMPPTRC

Prepare the IED for verification of settings as outlined in
settings".
Values of the logical signals for SMPPTRC are available on the local HMI under Main menu/
Tests/Function status/Logic/SMPPTRC(94,1->0)/X:SMPPTRC. The Signal Monitoring in
PCM600 shows the same signals that are available on the local HMI.
This function is functionality tested together with other protection functions (earth-fault
overcurrent protection, and so on) within the IED. It is recommended that the function is
tested together with the autorecloser function, or when a separate external unit is used for
reclosing purposes. The testing is preferably done in conjunction with the protection system
and autorecloser function.
7.7.1.1

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 functional TRIP output signal
must always appear.
7.7.1.2

Circuit breaker lockout

The following tests should be carried out when the built-in lockout function is used in addition
to possible other tests, which depends on the complete configuration of an IED.
