If we touch the Capacitor terminals you feel shock after the capacitor was put in operation and not in case of inductor though both are energy storage elements.why?
HAL,
4 10358When calculation of fault current and fault Kva is to be done,why always we use per unit value and why we consider the base kva?

6 12160can transformer work on dc or not?if we increase the inductance of transformer can it happen to work on dc?
1 38821)we r having one problem .one dry type transformer(6.6KV/433V)is taking high magnetizing current on delta connected HV side of "U" phase when compared to other two phases.could any body tell the reason why it is happening? 2)why CT secondary side protection core has got higher winding resistance when compared to that of metering core of same CT?
