can we done C.T.sc at output?
if yes y,if no y?

Answer Posted / manmohan

Unless a burden (i.e. meters, relays, etc.) is connected to
the CT, current transformers should always be shorted
across the secondary terminals. The reason is very high
voltages will be induced at the terminals. CT Secondary has
high resistance so it can be short circuited.
