Answer Posted / a.bala
30 / Rt3xpfx voltage i KV
30/Rt3 x.8x.440= 49.2 A
Consider starter current 1.2 Time from running current
so 49.2 * 1.2= 59 A
sO you will selecte cable and breaker for 60 A.

Define conversion efficiency of a power amplifier.
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.
