This standard describes electrical and mechanical requirements of liquid-immersed distribution and power transformers, and autotransformers and regulating transformers, single-phase and polyphase, with voltages of 601 V or higher in the highest voltage winding.This standard applies to all liquid-immersed distribution, power, and regulating transformers that do not belong to the following types of apparatus:a) Instrument transformersb) Step voltage and induction voltage regulatorsc) Arc furnace transformersd) Rectifier transformerse) Specialty transformersf) Grounding transformersg) Mobile transformersh) Mine transformers
Purpose
This standard is a basis for the establishment of performance, and limited electrical and mechanical interchangeability requirements of the equipment are described. It is also a basis for assistance in the proper selection of such equipment.
Abstract
Revision Standard - Inactive - Superseded.Electrical and mechanical requirements for liquid-immersed distribution and power transformers, and autotransformers and regulating transformers; single- and polyphase, with voltages of 601 V or higher in the highest voltage winding, are set forth. This standard is a basis for the establishment of performance, and limited electrical and mechanical interchangeability requirements of equipment are described; it is also a basis for assistance in the proper selection of such equipment. The requirements in this standard apply to all liquid-immersed distribution, power, and regulating transformers except the following: instrument transformers, step voltage and induction voltage regulators, arc furnace transformers, rectifier transformers, specialty transformers, grounding transformers, mobile transformers, and mine transformers.
