Abstract

Railways are one of the most important types of transportation in society. With continuous progress in technology, railways are constantly evolving toward long-distance transportation, high energy efficiency, high sustainability, and low carbon emissions. In electrified railway systems, locomotives are powered by a traction power supply system through a catenary. Electrical power can be supplied through a single-phase fundamental frequency 25-kV alternating current catenary or fractional frequency 15-kV current. For example, the standardized specification in China is single-phase 50-Hz 25-kV current. Train traction transformers are important devices.
