7.9.1.3
Completing the test
Continue to test another function or end the testing by setting the parameter
under Main menu/Tests/IED test mode/TESTMODE:1. If another function is tested, then set
the parameter
SMPPTRC(94,1->0)/SMPPTRC:X for the function, or for each individual function in a chain, to
be tested next. Remember to set the parameter
that has been tested.
7.9.2
Tripping logic phase segregated output SPTPTRC
Prepare the IED for verification of settings as outlined in section
settings.
Values of the logical signals for SPTPTRC are available on the local HMI under Main menu/
Tests/Function status/Logic/SPTPTRC(94,1->0)/SPTPTRC:X. 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 preferable done in conjunction with the protection system
and autorecloser function.
7.9.2.1
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.
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 auto-reclose attempt will follow.
Autorecloser STBRREC has functionality such as the long trip time, CB ready and so on,
which can prevent a proper single-phase tripping and auto reclose. To bypass this
problem the fault initiation should be with a test set and with the auto reclose 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 the autorecloser function. 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 the STBRREC function. 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. No other outputs should be active.
4.
Initiate a single-phase-to-earth fault and switch it off immediately when the trip signal is
issued for the corresponding phase.
5.
Initiate the same fault once again within the reclaim time of the used autorecloser
function.
A single-phase fault shall be given at the first fault. A three-phase trip must be initiated
for the second fault. Check that the corresponding trip signals appear after both faults.
Functional outputs TRIP, TRLn and TR1P should be active during first fault. No other
