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 voltage and
the phase angle between the voltage and current can be controlled. During the test the analog outputs of
active and reactive power shall be monitored.
1. Connect the test set for injection of voltage and current corresponding to the mode to be used in
the application. If a three phase test set is available this could be used for all the modes. If a single
phase current/voltage test set is available the test set should be connected to a selected input for
one phase current and voltage.
2. Adjust the injected current and voltage to the set rated values in % of IBase and VBase (converted
to secondary current and voltage). The angle between the injected current and voltage shall be set
equal to the set direction Angle1, angle for stage 1 (equal to 0° for low forward power 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 Angle1 + 90°. Check that the
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 Angle1 value. Increase the
current slowly from 0 until the PICKUP1 signal, pickup of stage 1, is activated. Check the injected
power and compare it to the set value Power1, power setting for stage 1 in % of Sbase.
5. Increase the current to 100% of IBase and switch the current off.
6. Switch the current on 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 test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.
