Editing High Impedance Detection settings

  1. On the Electric page, click the High Impedance Detection tab.

  2. In Medium Severity Threshold for Sudden Change of Impedance alarm, compared to the Base Threshold (%), type the threshold as a whole number. The default value is 200.

  3. In Medium Severity Threshold for a Gradual Increase of Impedance alarm, based on the increase of impedance over a year (%), type the threshold as a whole number. The default value is 100.

  4. In Medium Severity Threshold for Impedance Above Threshold alarm, compared to the Base Threshold (%), type the threshold as a whole number. The default value is 150.

  5. In High Severity Threshold for Sudden Change of Impedance alarm, compared to the Base Threshold (% above), type the threshold as a whole number. The default value is 400.

  6. In High Severity Threshold for a Gradual Increase of Impedance alarm, based on the increase of impedance over a year (%), type the threshold as a whole number. The default value is 200.

  7. In High Severity Threshold for Impedance Above Threshold alarm, compared to the Base Threshold (%), type the threshold as a whole number. The default value is 200.

  8. In Interval to mark events of the same type on the same transformer into the same issue group (Hours), type the threshold as a whole number. The default value is 24.
