For example, if the measured voltage jumps from 0 to 1.2 times the set start voltage level
and time multiplier k1 is set to 0.05 s (default value), then the TR1 and TRIP signals
operate at a time equal to 0.250 s ± tolerance.
8. Repeat the test for step 2.

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
ROV2PTOV(59N,2UN>)/ROV2PTOV:1 for the function, or for each individual function in a chain,
to be tested next. Remember to set the parameter
that has been tested.

Loss of voltage check LOVPTUV

Prepare the IED for verification of settings as outlined in section
settings".
Values of the logical signals for LOVPTUV are available on the local HMI under Main menu/
Tests/Function status/Voltage/LOVPTUV(27,U<)/LOVPTUV:1. The Signal Monitoring in
PCM600 shows the same signals that are available on the local HMI.
7.5.4.1

Measuring the operate limit of set values

1. Check that the input logical signals BLOCK, CBOPEN and VTSU are logical zero.
2. Supply a three-phase rated voltage in all three phases and note on the local HMI that the
TRIP logical signal is equal to the logical 0.
3. Switch off the voltage in all three phases.
After set
local HMI.
4. Inject the measured voltages at rated values for at least set
5. Activate the CBOPEN binary input.
6. Simultaneously disconnect all the three-phase voltages from the IED.
No TRIP signal should appear.
7. Inject the measured voltages at rated values for at least set
8. Activate the VTSU binary input.
9. Simultaneously disconnect all the three-phase voltages from the IED.
No TRIP signal should appear.
10. Reset the VTSU binary input.
11. Inject the measured voltages at rated values for at least set
