what is a railway traction transformer

Each traction transformer you see will be specifically designed to step down the high voltage and increase the current for the electric train and tram traction system. They step down the electricity to the level that is needed and manageable by the train traction system.

How these railways traction transformers are different from other transformers is how they are designed. These locomotive transformers are designed to handle dynamic loading and work in very harsh operation conditions they might face during their useful life.

These transformers have to provide extremely high current as the train starts to move and then gradually adjust it according to the speed. Same goes with when braking and stopping the train. These transformers make sure that they take on all the variations of load, voltage, and electric current and keep all other electric components of the train safe.

Key Benefits 

• Energy Efficiency

As these traction transformers are designed to power locomotives, they have to be very efficient and offer minimal losses to make the transportation affordable. These transformers have minimal power losses during voltage transformation. This improves overall system performance.

• Reliability

Designing stage of these transformers ensures robustness and manufacturing ensures a rigid structure to resist against the harsh operating conditions. This robustness and rigidity ensures consistent, reliability, and long term operation of the traction transformer.

• Compactness

As on-board traction transformers are installed on locomotives so they are always designed for compactness. The compact design allows for lightweight and space efficient transformers which is crucial for on-board applications.
