we converts this single phase into two phases by usin
capacitor, shaded rings.

Question { Siemens, 16045 }

How the electric train gets the supply of electricity? What
is the return path of the current?

Answer

Train moves on 25kv single phase AC voltage supplied through
the catenary wire by pantograph on the roof of the train .
then it goes through converter inverter process where the
voltage is reduced and make suitable for the 3 phase
induction motors.and the track is connected is connected as
return conducter

Question { Mitsubishi, 7065 }

why we used capacitor in induction motor?

Answer

Capacitor provides the starting torque & also improves the
power factor of the induction motors As they have low power
factor
