Indian Railway train electricity voltage: Train is the cheapest mode of travel in India. Indian Railways operates thousands of trains every day and lakhs of passengers travel through it every day. Since independence, India has also made many major changes in its railway system. Most of the trains are now run by electric locomotives in place of conventional fuel-powered locomotives. You must have traveled in the train at some time or the other and must have seen its fast speed. Have you ever thought that how much voltage must be required for such a heavy train to run at such a high speed? Let us tell you about it…
Train needs high power voltage
Let us tell you that the weight of the train engine itself is several tons. If we talk about the weight of the whole train, then we cannot even imagine it. High power voltage is required to pull such a heavy load at high speed. According to Ravel, about 25 thousand voltage is needed to run the train. This current is given to the engine of the train through the pantograph mounted on top of the engine. Pantograph gets this power from over head equipment ie OHE.
This is how electricity is supplied to the train
Let us explain to you the whole system of how the train gets electricity. In fact, you must have seen that the train never gets late due to power failure because the power supplied to the train never goes off. This is because railways get electricity directly from the power grid. Electricity is supplied to the grid from power plants, railways get electricity directly from the power grid, from here electricity is sent to substations. Direct 132 KV is supplied to the railway from the sub-station and from here a current of 12 thousand volts is given in the railway line.
Due to the continuous power supply in the railway line, you must have seen sub-stations along the railway line during your journey. Tripping never takes place here due to continuous power supply.
Which current does the train run on?
Now if we talk about whether AC current is required to run the train or DC current, then tell that DC current was given in the train in the initial days. But, DC current failed to run heavy trains. Later AC current was used in the train. With AC current, the train gets torque easily in the beginning, due to which the train picks up speed.
