When the installing procedure is successful, select the Submit and save inreport button. ICT will now forward a more accurate frequency to Parametersetting. In the Parameter setting tool, write the newly acquired parameter to IED.The accurate setting of this frequency is essential for proper operation of theprotection under different operating conditions.6.4 Performing calibration GUID-DE96CE75-A268-4FE1-AD9D-093EA1F2ECBA v21. From the Calibrating tab, select the first sub tab, i.e. Step1: Measurement 1.2. Make sure you have not attached any additional impedance in parallel with therotor.3. From the ICT toolbar, select the Start reading from IED button.The generator shall be in a condition that is as close as possible to the normaloperating condition as during the Installation.It is very important that calibration steps 1 to 3 is performed in theproper order. If not, the calibration might fail. If readings are notstable during the step, a warning to repeat the step may besuggested; the step shall be repeated in order to avoid that thecalibration fails.4. When the statistical error of the performed continuous measurements reaches anacceptable value, the indicator bar reaches the stability region (turned green), andit is allowed to select the Submit button.Clicking the Submit button the result is stored for later calculations.
