Rated transformer output is limited by heating and losses. There are two types of losses core loss and ohomic loss. Core loss depend on voltage(V) and ohomic loss depend on current(I)
and almost unaffected by the load power factor(pf). That is why rated output expressed in VA or kVA(V*I) not in KW(V*I*pf).

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened. Why does the strand conductor of Electrical power transmission line make twist?
