Before proceeding any further make sure that you have removed the short-circuit that was applied during calibration step 3.14. To finish the calibration process, select the Submit to Parameter settingbutton.15. In Parameter setting, write the newly acquired parameters to IED.6.5 Acquiring references GUID-AC1645F9-9B48-4F6A-9D81-BDCB7382533E v2To detect different operation conditions of the generator and select properimpedance reference requires logic outside the injection function. Thereforechanging/switching impedance reference is not described here but in a separateapplication note 1MRG005030 Application example for injection based 100%Stator EF and Sensitive Rotor EF protection.The injection commissioning tool (ICT) helps the commissioning engineer toacquire additional references for different conditions of the generator. The belowdescription assumes that reference 1 was set during calibration and that a secondreference must be set now.Section 6 1MRK 502 073-UEN ACalibrating injection based sensitive rotor earth fault protection66 Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062Commissioning manual
