Why lightning arrester blast in rainy day?
Answer Posted / n.bharat mohan
the main purpose of using lighting arrester is to suppress the high voltage caused due to lighting.during rainy day the effect of rain on the lighting arrestor will decrease its insulation value, which results in a heavy current to flow from the arrester, which raise to blast the arrester.

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.
