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.
Use the formulas stated in
mode
GOPPDOP(32,P>)/GOPPDOP:1/General.
2. Adjust the injected current and voltage to the set rated values in % of
(converted to secondary current and voltage). The angle between the injected current
and voltage shall be set equal to the set direction
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
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
the current slowly from 0 until the START1 signal, start of stage 1, is activated. Check the
injected power and compare it to the set value
Sbase .
5. Increase the current to 100% of
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 testing by setting the parameter
under Main menu/Tests/IED test mode/TESTMODE:1. If another function is tested, then set
the parameter
GOPPDOP(32,P>)/GOPPDOP:X for the function, or for each individual function in a chain, to be
tested next. Remember to set the parameter
has been tested.
