power protection). Check that the monitored active power is equal to 100% ofrated 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 thereactive power is equal to 100% of rated power.4. Change the angle between the injected current and voltage back to 0°. Decreasethe current slowly until the PICKUP1 signal, pickup of stage 1, is activated.5. Increase the current to 100% of IBase.6. Switch the current off and measure the time for activation of TRIP1, trip of stage1.7. If a second stage is used, repeat steps 2 to 6 for the second stage.13.5.10.2 Completing the test SEMOD175027-15 v4Continue to test another function or end the test by changing the TESTMODE setting toDisabled. Restore connections and settings to their original values, if they werechanged for testing purposes.13.5.11 Directional overpower protection GOPPDOP (32) SEMOD175058-3 v5Prepare the IED for verification of settings outlined in Section "Preparing the IED toverify settings".13.5.11.1 Verifying the settings SEMOD175058-7 v6The overpower protection shall be set to values according to the real set values to beused. The test is made by means of injection of voltage and current where theamplitude of both current and voltage and the phase angle between the voltage andcurrent can be controlled. During the test the analog outputs of active and reactivepower shall be monitored.1. Connect the test set for injection of voltage and current corresponding to themode to be used in the application. If a three phase test set is available this couldbe used for all the modes. If a single phase current/voltage test set is available thetest 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 andVBase (converted to secondary current and voltage). The angle between theinjected current and voltage shall be set equal to the set direction Angle1, anglefor stage 1 (equal to 0° for low forward power protection and equal to 180° for1MRK 502 073-UUS A Section 13Testing functionality by secondary injectionGenerator protection REG670 2.2 ANSI and Injection equipment REX060, REX061, REX062 209Commissioning manual
