why transfromer rating gives in MVA Or KVA? Why not in MW
or KW?

Answer Posted / blaji

loss of trasformer dependes on voltage and current only,
not the angle between them...

anythink give supply rated on KVA--Alternator-chock-trasfo.
anythink takes power termed in KW-light-bulb,load,,,

at the time of designe we do not know about load PF,that y
Alternator rated in KVA,,

but we knew pf of any motor after designe...so we can add it

Power=V*I*pf....bk_kangaonkar@yahoo.co.in
