Special Application Transformers

Induction & Arc Furnace Transformers

Being in service for last two decades, Skipper Arc and Induction Furnace Transformers are extensively used in industry applications round the clock in steel plants available from 1 MVA to 50 MVA. Transformers with extended delta design are also manufactured to reduce system harmonics due to the usage of power (current) as a major resource for electric Power. They are specifically designed to supply the necessary power even at a low voltage.

Special Feature

Direct or Indirect regulation
On-load or off-circuit tap changer
Built-in reactor for long arc stability
Air or water-cooled secondary bushing arrangements
Internal secondary phase closure (Internal Delta)
Ratings up to 250 MVA
Secondary voltage up to 1,500 V (LF down to 80 V)
Electrode current for steel up to 120 kA
Electrode current for ferroalloy up to 180 kA
Skipper Transformers are designed for continuous and interrupted load.
