But is it advisable to keep the secondary of CT in open conditions? Will not induce very high voltage?
by

1 Answer

Answer :

If the CT has only one secondary winding, we should keep it always short cktd for safety, but if the CT has multiple secondary, then if one secondary voltage is kept limited by suitable loading, then the other secondary voltage is eventually limited proportionately.
