Why Current Transformer (CT) Seconday Should not be Open never open the secondary winding circuit of a current transformer while its primary winding is energized. Thus most of the current transformers have a short circuit link or a switch at secondary terminals. When the primary is to be energized, the short circuit link must be closed so that there is no danger of open circuit secondary.
