1. Connect the test set for injection of three-phase currents and three-phasevoltages to the appropriate current and voltage terminals of the IED.2. Inject current(s) and voltage(s) in a way that relevant measured (according tosetting parameter CurrentInput and VoltageInput) currents and voltages arecreated from the test set.3. Set the relevant measuring quantity current to lag or lead (lag for negativeRCA angle and lead for positive RCA angle) the relevant polarizing quantityvoltage by an angle equal to the set IED characteristic angle (rca-dir) whenforward directional feature is selected and the CTstarpoint configurationparameter is set to ToObject.If reverse directional feature is selected or CTstarpoint configurationparameter is set to FromObject, the angle between current and polarizingvoltage shall be set equal to rca-dir+180°.4. Overall check in principal as above (non-directional overcurrent feature)5. Reverse the direction of the injection current and check that the protectiondoes not operate.6. Check with low polarization voltage that the feature becomes non-directional,blocked or with memory according to the setting.13.8.1.5 Over/Undervoltage feature SEMOD56488-83 v2Procedure1. Connect the test set for injection three-phase voltages to the appropriatevoltage terminals of the IED.2. Inject voltage(s) in a way that relevant measured (according to settingparameter VoltageInput) voltages are created from the test set.3. Overall check in principal as above (non-directional overcurrent feature) andcorrespondingly for the undervoltage feature.13.8.1.6 Completing the test SEMOD56488-99 v2Continue to test another function or end the test by changing the TESTMODEsetting to Off. Restore connections and settings to their original values, if they werechanged for testing purposes.13.9 Secondary system supervision SEMOD53556-1 v113.9.1 Current circuit supervision CCSSPVC M12917-25 v8Prepare the IED for verification of settings outlined in Section "Preparing the IEDto verify settings".The Current circuit supervision function CCSSPVC is conveniently tested with thesame three-phase test set as used when testing the measuring functions in the IED.1MRK 502 073-UEN A Section 13Testing functionality by secondary injectionGenerator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 223Commissioning manual
