Its all depends on the amount of insulation between them
rather than the distance

Equal to the length of the earthing electrode. Actually
earth wire should not be very long to increase effective IR
value and earth pit should not be a hindrance being very
close.

How can calculate the rating of a alternator for a given specific load with formula
0 Answers NRSC National Remote Sensing Centre,
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.
