clearance between the phases & neutral to be check for normal operation ,if the check done properly means we can assure the equipments will not affect during short circuit

Answer / k.prakashchandra

I don't think so.Single phase AC is provided for
illumination and space heaters, and normal DC supply.You can
check insulation and operations s/a closing & opening .
Relays and annunciations can also be checked.

If a 3 phase induction motor is in off condition in the conveyor and rotor of the motor keeps moving with the conveyor than the resistance of windings of motor varies. why is it so ??
