what is the primary current in 415/415 v when secondry of
dry type transformer is shorted.?

Answer Posted / naresh kinger

It will be 139/4.7 x 100 = 3415 AMP on secondry side.

Since ratio is 1/1, primary current will also be 3415 AMP.

Hope it clear now. For any doubt, you can write me at

current transformer balance the power level on both sides. e.g in case of step up, at secondary side voltage rise but current decrease and vice versa in case of step down transformer. but how this power level remains same in case of current transformer and voltage transformer
