Why CT is never operated with an open secondary ?
Why CT is never operated with an open secondary ?
Last answer:
CT secondary should never be kept open because it will cause saturation of the core to a high level and very high voltage will appear across the secondary which can breakdown the insulation. One terminal of PT secondary is always grounded to avoid capacitive induction and for human safety
