Hi,
A transformer is rated 20kva 3300/200V. To circulate rated current in the primary, what is the value of the voltage to be applied and how to arrive at it?
My doubt is in Short circuit test, we apply a voltage less than the rated on primary to get rated primary current. But rated primary current is calculated by :(20kva/3300).. I am terribly confused. Somebody please hel me..
