Answer / himadri bag
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).
