Extended testing
Procedure:
1. The test above can be repeated to check the time to reset.
2. The tests above can be repeated to test the voltage dependent inverse time
characteristic.
Verification of the low voltage magnitude blocking
Procedure:
1.
2. Check that the IED settings are appropriate, especially the StartFrequencyand
the tDelay and the MinValFreqMeas in the SMAI preprocessing function.
3. Supply the IED with three-phase voltages at rated values.
4. Slowly decrease the magnitude of the applied voltage, until the BLKDMAGN
signal appears.
5. Note the voltage magnitude value and compare it with the set value
MinValFreqMeas.
6. Slowly decrease the frequency of the applied voltage, to a value below
StartFrequency.
7. Check that the START signal not appears.
8. Wait for a time corresponding to tDelay, and check that the TRIP signal not
appears.

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.

Over frequency protection SAPTOF

Prepare the IED for verification of settings as outlined in
verify settings".
Values of the logical signals are available on the local HMI under: Main menu/
Tests/Function status/<Function group>/<Function>/<1:Function>. The Signal
monitoring tool in PCM600 shows the same signals that are available on the LHMI.
