Revision Standard – Inactive – Superseded. Superseded by IEEE Std C57.12.01-2005 Electrical, mechanical, and safety requirements of ventilated, nonventilated, and sealeddry-type distribution and power transformers or autotransformers, single and polyphase, with a volt-age of 601 V or higher in the highest voltage winding, are described. Information that can be usedas a basis for the establishment of performance, interchangeability, and safety requirements ofequipment described, and for assistance in the proper selection of such equipment, is given.
