As per IE Rules 1956,for EHT line the clearance above ground
of the lowest conductor shall not be less than 5.2 m + 0.3 m
for every 33000 V or part thereof by which the voltage
exceeds 33000 V ,provided the minimum clearance along or
across any street shall not be less than 6.1 m. So for 400
KV line, it works out to be 8.8 m

Answer / alap

ground clearence means the height of middle of line between
two towers from ground... it is so designed as the sag is
minimum and stress on transmittion line is also minimum....

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.
