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 Rectifier and Converter Transformers need a specific design to supply the necessary power at a low voltage level. These transformer types (EAF Transformers and Ladle Furnace Transformers), as well as converter transformers for large drive applications are called special-purpose or Industry Transformers, whose design is tailor-made for high-current solutions for industry applications.

Regulating transformers in front of EAF as well as Rectifier transformers supplied by Siemens are designed for continuous and interrupted load. Short time load could reduce the size of the transformer. A higher number of switches on of the transformer, above the defined acc. IEC (more than 24 times per year) could be considered in the design for transformers used in the environment of industrial applications. are designed for continuous and interrupted load.
