Why transformer, generator, ups rating kva? ..

Answer / vishal ingle

rating is given in KVA / MVA because the power factor of
the lod to be connected is not known. for a specific fixed
real power (MW), the current depends on the power factor.
higher the p.f., lesser is the current & viceversa.
the condustor size inside the trf/ alternator is decided
depending on current.
hence KVA capacity is mentioned always.
