Types Of Traction Transformers

There are four main types of traction transformers that are divided into two main classes.

• Classification Based on Application

The traction transformers are two basic types based on the major application.

AC Traction Transformer

The AC traction transformers are designed and developed to power your long distance high distance electric trains using AC power supply and powering AC motors. They work as the same step down transformer here.

DC Traction Transformer

These DC traction transformers are designed for direct current and are used in applications like metro trains, trams, and other suburban railways you see all round you. They are efficient and highly reliable for short distance electrically powered locomotives.

• Classification Based on Installation Type

Traction transformers can also be classified based on the design that is developed to satisfy specific installation requirements.

Stationary Transformer

Stationary traction transformers are designed and developed for stationary installation at your local substations. These transformers step down the voltage at the substation before supplying it to the moving train through the railway overhead system or using the railway third rail system.

On-board Transformer

These transformers have a compact design and are made very light weight. This is because they are installed on locomotives and they move with those locomotives. They take supply from the railway overhead system or using the railway third rail system, step down the electricity and deliver it to the train or tram electrical system.
