Core of Transformer is being Earthed, because if you see the
Hysteresis Curve, flux doesn't decay to zero. If there is
some flux, it means there must be some amount of voltage and
hence the current. To avoid this shock, core is needed to be
earthed. It doesn't affect in Distribution Transformer due to
low voltage, but in case of power transformer it does.

We have a distribution transformer of 750KVA/11kv/440v and an AVR (Servo Stabilizer) of 750KVA on the LT side of distribution transformer. Also we have an ACB of 1200A on the output of distribution transformer (that is on the input of AVR). We want to have an MCCB on the output of AVR. What should be the rating?
