what type circuit breaker is suitable for connecting 1000A load VCb,Mccb?
Answer Posted / antaratara ghosh
you need to tell the voltage level to know the answer..
If it is HV, you have to go for 1250 A VCB or SF6..
If it is LV, go for 1250 A ACB..
In India, you wont find MCCB of more than 630/800 A..

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened. Why does the strand conductor of Electrical power transmission line make twist?
