New IEEE Standard – Inactive – Superseded. Superseded This standard is a compilation of terminology and definitions primarily related to electrical transformers and associated apparatus included within the scope of ANSI Committee C57, Transformers, Regulators, and Reactors. It also includes similar data relating to power systems and insulation that is commonly involved in transformer technology.<\/p>\n
