1.
Check that you have appropriate settings in the IED, especially the START
value and the definite time delay.
2.
Supply the IED with three-phase voltages at their rated values.
3.
Slowly increase the frequency of the applied voltage, until the START signal
appears.
4.
Note the operate value and compare it with the set value.
5.
Decrease the frequency to rated operating conditions.
6.
Check that the START signal resets.
7.
Instantaneously increase the frequency of the applied voltage to a value about
20% higher than the operate value.
8.
Measure the time delay for the TRIP signal, and compare it with the set value.
Extended testing
Procedure:
1.
The test above can be repeated to check the time to reset.
Verification of the low voltage magnitude blocking
Procedure:
1.
Check that you have appropriate settings in the IED, especially the
StartFrequency, TtDelay and the MinValFreqMeas in the SMAI
preprocessing function
2.
Supply the IED with three-phase voltages at their rated values.
3.
Slowly decrease the magnitude of the applied voltage, until the BLKDMAGN
signal appears.
4.
Note the voltage magnitude value and compare it with the set value,
MinValFreqMeas.
5.
Slowly increase the frequency of the applied voltage, to a value above
StartFrequency.
6.
Check that the START signal does not appear.
7.
Wait for a time corresponding to tDelay, and make sure that the TRIP signal
does not appear.
Completing the test
Continue to test another function or end the testing by setting the parameter
TestMode to Off under Main menu/Tests/IED test mode/1:TESTMODE. If
another function is tested, then set the parameter Blocked to No, under Main menu/
Tests/Function test modes/<Function group>/<Function>/<1:Function> for the
function, or for each individual function in a chain, to be tested next. Remember to
set the parameter Blocked to Yes, for each individual function that has been tested.
