How electric trains get electric supply?
CS Electrical And Electronics Staff asked 1 year ago
Hey, Guys, Do You Know?
How do electric trains get an electric supply?
Well, let me explain.
Third rail and pantograph are two different methods used to
supply electrical power to trains in railways.
A third rail system involves a third rail located beside
or between the railway tracks,
which carries electrical power to the train.
The train then collects power from the third rail using a shoe that touches the rail.
Third rail systems are commonly used in urban areas for metro trains.
It carries 750 volts of DC.
On the other hand, a pantograph is a mechanical device
mounted on the roof of a train that collects
electrical power from overhead wires.
The pantograph has a contact shoe that rests on the overhead wire
and collects power through it.
This method is commonly used for long-distance trains
and high-speed rail systems.
It carries 25 kV AC
That’s All
