Vpickup< Set pickup voltage for step 1
For example, if the measured voltage jumps from the rated value to 0.8 times the set pickup
voltage level and time multiplier TD1 is set to 0.05 s (default value), then the TRST1 and TRIP
signals operate at a time equal to 0.250 s ± tolerance.
10. The test above can be repeated to check the inverse time characteristic at different voltage
levels.
11. Repeat the above-described steps for step 2.

Completing the test

Continue to test another function or end the testing by setting the parameter
Disabled under Main menu/Tests/IED test mode/TESTMODE:1. If another function is tested, then
set the parameter
UV2PTUV(27,2U<)/UV2PTUV:1 for the function, or for each individual function in a chain, to be
tested next. Remember to set the parameter
been tested.
7.5.2

Two step overvoltage protection OV2PTOV (59)

Prepare the IED for verification of settings as outlined in the section
settings".
Values of the logical signals for OV2PTOV (59) are available on the local HMI under Main menu/
Tests/Function status/Voltage/OV2PTOV(59,2U>)/OV2PTOV:1. The Signal Monitoring in
PCM600 shows the same signals that are available on the local HMI.
7.5.2.1

Verification of single-phase voltage and time delay to operate for Step 1

1. Apply single-phase voltage below the set value
2. Slowly increase the voltage until the PU_ST1 signal appears.
3. Note the operate value and compare it with the set value.
