why, when birds sit on transmission lines or current wires
doesn't get shock?
Answer Posted / senthil kumar.a
basically the current is flow b/w only a closed circuit.the
current is flow when circuit is closed. the birds are sit
either phase or netural . it cause the circuit is not
closed. so no current flow there, sometimes u seen the
birds are dead, at that time they wings are un fortunately
touch the any other line,
not birds only in case we r touch the any one line we
cannot get shock,

what is droop control?
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.
