Answer / k.prakashchandra

As the voltage is high ,the current is less.So ,instead of
having 3 windings of line voltage ,you can have 3 windings
of phase voltage to save on insulation and others.Iron
losses are also reduced.

why we r using 4-20ma instead of 0-20ma in instrumentation

A group of machines (wind turbines) connected with 33KV feeder and each machines are having individual VCB. The 33KV feeder connected with 110KV/33KV substation. The 33KV feeder tripped by over current at Substation and fault recorded at Substation as OC-R&Y phase. Same time the group of machines VCB tripped by over voltage, the fault recorded voltage was above 66KV by numerical Under/Over voltage relay. While grid drop time, this much of voltage hike is possible?
