Block Diagram of an AC LocomotiveThe following figure shows the block diagram of an AC locomotive.AC Locomotive - Function of Each PartThe working and function of each part of an AC locomotive is described below −The AC power at 25 kV is taken from the overhead conductor wire (called as catenary) through a pantograph and this high voltage supply is fed to a step–down transformer (provided with on load tap changer) installed in the locomotive itself, which converts the high voltage AC supply to low voltage AC supply.This low voltage AC supply obtained from the transformer is then converted into ...
