Two step overvoltage protection OV2PTOV

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.

Verifying the settings

Procedure
1. Apply single phase voltage below the set value U1>.
2. Slowly increase the voltage until the ST1 signal appears.
3. Note the operate value and compare it with the set value.
4. Switch the applied voltage off.
5. Set and apply about 20% higher voltage than the measured operate value for
one phase.
6. Measure the time delay for the TR1 signal and compare it with the set value.
7. Repeat the test for step 2.

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.
