why current transformer secondary side should be shorted ?
Answer Posted / leo thomas
In CTs only a negligible part of the primary ampere turns
is used to magnetising the core .Remaining ampere turns is
counter balanced by secondary due to shorted.Once opening
CT in energised condition high voltages presents in
secondary causing faintal shock and the CT core will damage
