At the designing of transformer you can not predict which
type of load is placed on thatone i.e; the power factor is
unknown.under no load conditions thhe transformer losses is
depend on nearly sqare of voltage.under load condition the
losses depends on sqare of current.So overall losses in
transformer is depends on voltage and current only,so yhe
rating is inKVA

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.
