A traction transformer is a specialized type of electrical transformer used primarily in electric locomotives, high-speed trains, trams, and other electric rail vehicles to step down the voltage from the overhead lines or third rail to a level suitable for the traction motors. These transformers play a crucial role in the power supply system of electric railway vehicles, ensuring efficient and safe power conversion.

Key features and functions of a traction transformer include:

1. Voltage Transformation.

2. Isolation.

3. Adaptability.

4. Harmonic Filtering.

5. Temperature Management.

6. Robustness and Reliability.

Overall, the traction transformer is a critical component in the electrification of railways, enabling the efficient conversion of electrical energy into mechanical energy for propulsion, thereby driving the train forward. Its design and performance are instrumental in achieving reliable, efficient, and eco-friendly rail transportation.
