IEEE PC57.17

Revision Standard - Active - Draft.
The electrical characteristics and mechanical features of liquid-immersed transformers 69 kV or less (but not limited to 69 kV), used for supplying electric power to direct arc-melting furnaces are covered in this standard.

This standard covers electrical characteristics and mechanical features of liquid-immersed transformers, used for directly supplying electric power to arc-melting furnaces (including rectifiers for arc-melting furnaces). All characteristics and definitions, except as specifically covered in this standard, shall be in accordance with the IEEE Requirements for Liquid-Immersed Distribution, Power, and Regulating Transformers (C57.12 Series).
The purpose is to provide an industry standard on the design and application of power and distribution transformers for the specific application of feeding arc furnaces and related foundry equipment.
