We travel comfortably from train to home enjoying the cool air from the fan. Have you ever wondered where the electricity comes from?

 

 Train: You must have traveled in Indian Railways at least once. You must have also enjoyed the fan and AC while traveling. Most of the people in India prefer to travel by train because traveling in train is the easiest, affordable and convenient option, but have you ever wondered? Where does the electricity come from for the fan or AC running in the train and how much is consumed? Which does not disappear even for a second. If you also do not know the correct answer to this, then today we will tell you about it through this article. You must know the answer to these questions because 99 percent of the people do not know the answer.

How do we get electricity supply?

If you do not know where the train gets electricity from, then let us tell you that the railways get electricity directly from the power grid and electricity comes to these grids from the power plant. After this, electricity is sent to the substations through the grid. According to the railways, electric trains require 25 thousand volts (25KV). This current comes to the engine through a device called pantograph mounted on the engine. The pantograph runs by rubbing against the wires mounted on the train. Electricity comes to the train through these wires. Actually, there are two types of wires in these wires tied to the poles, in which the upper one is the co-tenant wire and below it is the contact wire. A gap is maintained between these two wires through drop. Due to this, the wire always remains below and is connected to the pantograph. With the help of the pantograph, current is kept from the wire mounted above. The 25KV i.e. 25,000 volt current flowing in it comes to the main transformer of the electric engine, which runs the engine.

Why doesn't the power go off?

Indian Railways uses 25,000 volt single phase 50Hz alternating current for rail operations, which is converted into 750 volt three phase alternating current inside the electric locomotive to run the three phase alternating current squirrel cage motors fitted on its wheels. This is why substations are often seen near railway stations. Apart from this, let us tell you that these never trip due to direct supply from the power grid. If sometimes a line gets shut down due to any reason, then supply starts from another grid. Due to getting power directly from the power grid, the railway's power loss is almost negligible.
