Abstract

This standard is intended as a basis for the establishment of performance, limited electrical and mechanical interchangeability, and safety requirements of equipment described; and for assistance in the proper selection of such equipment. This standard describes electrical, mechanical, and safety requirements of liquidimmersed distribution and power transformers, and autotransformers and regulating transformers; single and polyphase, with voltage 601 V or higher in the highest voltage winding. This standard applies to all liquid-immersed distribution, power, and regulating transformers except as indicated below: (1) Instrument transformers (2) Step-voltage and induction voltage regulators (3) Arc furnace transformers ( 4) Rectifier transformers (5) Specialty transformers (6) Grounding transformers (7) Mobile transformers (8) Mine transformers When this standard is used on a mandatory basis, the words shall and must indicates mandatory requirements; and the words should and may refer to matters which are recommended or permissive, but not mandatory. NOTE: The Foreword of this voluntary consensus standard describes the circumstances under which the standard may be used on a mandatory basis.
