Use the TRIP signal from the configured binary output to stop the timer.12. Deactivate the CLOSECMD: Set measured current in one phase to 90% ofCurrent Release level. Activate CLOSECMD.NO TRIP signal should appear.13. Repeat the previous two steps using OPENCMD instead of CLOSECMD.Asymmetry current detection with CB monitoring: Set all three currents to 110%of Current Release level. Activate CLOSECMD.NO TRIP signal should appear due to symmetrical condition.14. Deactivate the CLOSECMD. Decrease one current with 120% of the currentunsymmetrical level compared to the other two phases. Activate CLOSECMDand measure the operating time of the CCPDSC (52PD) protection.Use the TRIP signal from the configured binary output to stop the timer.15. Deactivate the CLOSECMD. Decrease one current with 80% of the currentunsymmetrical level compared to the other two phases. Activate CLOSECMD.NO TRIP signal should appear.13.5.9.2 Completing the test SEMOD55625-106 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.13.5.10 Directional underpower protection GUPPDUP (37) SEMOD175027-3 v5Prepare the IED for verification of settings outlined in Section "Preparing the IED toverify settings".13.5.10.1 Verifying the settings SEMOD175027-7 v7The underpower 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 the amplitude ofboth current and voltage and the phase angle between the voltage and current can becontrolled. During the test, the analog outputs of active and reactive power shall bemonitored.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.1MRK 502 073-UUS A Section 13Testing functionality by secondary injectionGenerator protection REG670 2.2 ANSI and Injection equipment REX060, REX061, REX062 207Commissioning manual
