13. 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 setting button.
15. In Parameter setting, write the newly acquired parameters to IED.
6.5 Acquiring references
GUID-AC1645F9-9B48-4F6A-9D81-BDCB7382533E v2
To detect different operation conditions of the generator and select proper impedance
reference requires logic outside the injection function. Therefore changing/switching
impedance reference is not described here but in a separate application note
1MRG005030 Application example for injection based 100% Stator EF and Sensitive
Rotor EF protection.
The injection commissioning tool (ICT) helps the commissioning engineer to acquire
additional references for different conditions of the generator. The below description
