ELCB and RCCB also working with Neutral so your welding transformer may be earth leakage or neutral short with your earth so first you it

Answer / raghav govind

Because rccb works under unbalance current flowing in the desired circuit...if a man stuck, were in electric shock...if its in single phase protection breaker....the circuit will allow even current... Not unbalance current flow...since the breaker will not trip in this situation...definitely...

At 765Kv, I have seen the use of PT at line side for metering and CVT for protection, although as far as my knowledge is concern, PT at this voltage level will have huge loss and more cost as compared to CVT as CVT can also perform same function of Protection and Metering? So my question is why use PT and not CVT for metering and protection in order to reduce the cost.
