As rating unit of any equipment depend upon the factora
which influence its output,and output depend upon the
losses. so as in transformer the cupper loss depend upon
current and iroin loss depend upon the vlotage,and not on
powerfactor.
as we know kw= volt*current8power factor
and Kva= vlot*amp
so its very logical; to rate the transformer in KVA

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
