A number of industry applications require specific industrial transformers due to the usage of power (current) as a major resource for production. Electric arc furnaces (EAF), ladle furnaces (LF) and high-current rectifiers need a specific design to supply the necessary power at a low voltage level. These transformer types, as well as converter transformers for large drive applications are called special-purpose or industrial transformers, whose design is tailor-made for high-current solutions for industry applications.

 

Rectifier Transformers are combined with a diode or thyristor rectifier. The applications range from very large aluminium electrolyses to various medium-size operations.

Converter transformers are mostly build as double-stack, with two secondary windings. Such transformers normally have an additional winding for filter purposes to take out harmonics.

There's different kinds of furnace transformers:
Electric Arc Furnace (EAF) Transformers,
Electric Arc Furnace Series Reactors,
DS Electric Arc Furnace Transformers
