Answer Posted / amr mobarak
From the Theory of Design of any transformer we know that :-
S(primary ) = S(secondary ) , neglecting the Losses
I.V (primary ) = I.V (secondary )
So When We Try to Describe any Transformer We Refer to VA or
KVA or MVA as their Values are the Key of Design not The
Power ( Active or Reactive ).
