Answer Posted / guest
when open circuit test of transformer we will got the iron
loss it will depends upon voltage and during short circuit
test we will got the copper loss it will depend upon
current there fore total loss in VA so we use large
capacity of transormer hencetransformer capacityis in KVA.
2)if ct secondary is open heavy emf will produced so
sarrounding equepement will burntout and CT willalso burnt
or saturated.
