why rating of transformer is in KVA but of motor is in KW
Answer Posted / krish
1)Transformer is an static device and original it has no PF(
when no load is connected to it),only real power is taken
into account,motors use both real and reactive power for
working so its rating is in KW
2)in transformer iron loss and copper loss is taken in
consideration so KVA is used
