Description / Abstract:
This standard covers 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.
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 Transformer (C57.12 Series).
Purpose
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.
