Abstract

This standard describes electrical and mechanical requirements of single and polyphase ventilated, nonventilated, and sealed dry-type distribution and power transformers or autotransformers, with a voltage of 601 V or higher in the highest voltage winding. This standard applies to all dry-type transformers, including those with solid-cast and/or resin encapsulated windings except as follows: a) Instrument transformers b) Step and induction-voltage regulators c) Arc-furnace transformers d) Rectifier transformers e) Specialty and general-purpose transformers f) Mine transformers g) Testing transformers h) Welding transformers NOTE—Where IEEE standards do not exist for the transformers mentioned above or for other special transformers, this standard may be applicable as a whole or in parts subject to agreement between the parties responsible for the application and for the design of the transformer.5 Purpose This standard is intended to serve as a basis for the establishment of performance, interchangeability requirements of equipment described, and for assistance in the proper selection of such equipment. 5Notes in text, tables, and figures are given for information only and do not contain requirements needed to implement the standard.
