5. Increase the current to 100% of IBase.
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
TestMode to Off under Main menu/Tests/IED test mode/1:TESTMODE. If
another function is tested, then set the parameter Blocked to No under Main menu/
Tests/Function test modes/Current/GUPPDUP(37,P<)/1:GUPPDUP for the
function, or for each individual function in a chain, to be tested next. Remember to
set the parameter Blocked to Yes, for each individual function that has been tested.

Directional overpower protection GOPPDOP

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

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
The set mode Mode can be found under Main menu/Settings/IED Settings/
Current/GOPPDOP(32,P>)/1:GOPPDOP/General.
2. Adjust the injected current and voltage to the set rated values in % of IBase
and UBase (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
