IEEE Approved Draft Standard for Traction Power Transformers for Substation Applications up to 1500 Volts DC Nominal Output

This standard is a guideline for establishing criteria for application, performance, interchangeability, tests, life cycle costs and safety requirements of traction power rectifier transformers. Electrical, mechanical and thermal design, manufacturing, and testing requirements are set forth for traction power rectifier transformers for DC electrification systems. This standard covers Liquid-immersed and Dry-type transformers, including those with cast coil and epoxy resin encapsulated windings
