Answer Posted / j.prakash
Transformer is static device there is no any rotating part
so there is no any friction losses, only iron loss and cu
loss in transformer, iron loss depend upon the voltage and
cu loss depend upon the current, there in no any loss which
depend upon power factor,so rating of transformer only in
kva.SO NOT IN KW..

why the voltage and current in a long transmission line are called travelling wave?
In a 3 phase 4-wire system. For a 3.5 core cable if all loads are single phase and balanced, what will be neutral current? will it be sum of all phase currents? Or it will be zero? And if loads are unbalanced what will be neutral current?
why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating. What about when you have a vaccuum cleaner intake flush against a floor, a room fan sitting directly against a wall, or a power drill trying to drill through something too hard?
