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.
11.5 Acquiring references
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 assumes that reference 1 was set during calibration and that a second
reference must be set now.
