IEEE 1653.1-2026

This standard covers design, manufacturing, and testing unique to the application of power rectifier transformers intended to operate in dc-supplied transportation substation applications up to 1500 V dc nominal output.

This standard provides requirements specific to traction power transformers supplying power to dc supplied transportation equipment

Revision Standard - Active. Guidelines for establishing criteria for application, performance, interchangeability, tests, life cycle costs, and safety requirements of traction power rectifier transformers are established in this standard. Set forth are the electrical, mechanical, and thermal design, manufacturing, and testing requirements for traction power rectifier transformers for dc electrification systems. Liquid-immersed and dry-type transformers, including those with cast-coil and epoxy-resin-encapsulated windings, are covered by this standard.
