Inactive-Withdrawn Standard

IEEE/ANSI C57.12.52-1981

American National Standard Requirements for Sealed Dry-Type Power Transformers, 501 kVA and Larger, Three-Phase, with High-Voltage 601 to 34 500 Volts, Low-Voltage 208Y/120 to 4160 Volts

This standard is intended to set forth characteristics relating to performance, limited electrical and mechanical interchangeability, and safety of the equipment described, and to assist in the proper selection of such equipment. 1.2 This standard describes certain electrical and mechanical characteristics and takes into consideration certain safety features of 60-Hz, two-winding, three phase, sealed dry-type transformers rated 501 kVA and larger, generally used for step-down purposes. Specific rating combinations are described in the range from 750 to 5000 kVA inclusive, with high-voltage 2400 to 34 500 volts inclusive and low-voltage 208Y/120 to 4160 volts inclusive. 1.3 This standard does not apply to other types of transformers, such as specialty, ventilated dry-type, pad-mounted dry type, liquid immersed, instrument, regulating, furnace, mine, and rectifier transformers. 1.4 When this document is used on a mandatory basis, the word "shall" indicates mandatory requirements, and the words

Other Activities From This Working Group

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.


No Active Projects

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.


No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
