The 25 KV single phase AC supply is applying to the step
down transformer by the feeding post line.The return path
of the current is track line.the track line is connected to
the proper earth for the safety purpose.The stepped down AC
supply is converted to the rectified DC supply by the
rectifier, filter circuit.now the DC supply is connected to
the DC series motor.DC series motor is very suitable for
startind high torque.
