What are the characteristics of a traction power transformer, and where is it used?

A traction power transformer is designed to handle high power levels with robust mechanical and thermal properties to withstand the demanding conditions of railway operations. Key characteristics include high efficiency, compact size, low weight, and the ability to operate under variable loads and environmental conditions. They often feature advanced cooling systems and insulation materials. Traction power transformers are used in electric locomotives, multiple units, high-speed trains, and in trackside substations for railway electrification systems, providing the necessary voltage conversion and power distribution for railway networks.
