Why CT Secondary should not be open circuited?
The secondary side of a current Transformer should never be kept in open condition,
because When kept open There is a very high voltage found across the secondary side.
This high voltage Causes a high magnetizing current to built up on the secondary side which in turn causes high flux and makes the core to saturate and also Ct damage.
if the secondary coil shorted, the current in this coil is so directed that it opposes a change of the flux. Therefore the variation of the flux is much smaller, and so is the induced voltage in the Secondary coil is less.
