2. Adjust the injected current and voltage to the set values in % of
to secondary current and voltage). The angle between the injected current and voltage shall
be set equal to the set direction
protection and equal to 180° for reverse power protection). Check that the monitored active
power is equal to 100% of rated power and that the reactive power is equal to 0% of rated
power.
3. Change the angle between the injected current and voltage to
monitored active power is equal to 0% of rated power and that the reactive power is equal to
100% of rated power.
4. Change the angle between the injected current and voltage back to 0°. Decrease the current
slowly until the PICKUP1 signal, pickup of stage 1, is activated.
5. Increase the current to 100% of
6. Switch the current off and measure the time for activation of TRIP1, trip of stage 1.
7. If a second stage is used, repeat steps

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
GUPPDUP(37,P<)/GUPPDUP:1 for the function, or for each individual function in a chain, to be
tested next. Remember to set the parameter
been tested.

Directional overpower protection GOPPDOP (32)

Prepare the IED for verification of settings as outlined in section
settings".
Values of the logical signals for GOPPDOP (32) are available on the local HMI under Main menu/
Tests/Function status/Current/GOPPDOP(32,P>)/GOPPDOP:X. The Signal Monitoring in PCM600
shows the same signals that are available on the local HMI.
7.4.9.1

Verifying the settings

The overpower protection shall be set to values according to the real set values to be used. The
test is made by means of injection of voltage and current where the amplitude of both current and
