Characteristics relating to performance, limited electrical and mechanical interchangeability, and guidance to assist in the proper selection of sealed dry-type transformers are provided in this standard. Specific rating combinations are described in the range from 750 to 5000 kVA inclusive, with high-voltage 2400 to 34500 Volts inclusive and low-voltage 208Y/120 to 4160 Volts inclusive. Sealed dry-type power transformers filled with only dry air or nitrogen, at the time of filling, are considered. Other gases are not considered in this standard. 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.

PC57.12.52
IEEE Draft Standard for Sealed Dry-Type Distribution and Power Transformers
Characteristics are provided in this standard relating to performance, limited electrical and mechanical interchangeability, and guidance to assist in the proper selection of sealed dry type transformers having a high voltage of at least 601 Volts. Specific rating combinations are described in the range from 750 to 5000 kVA inclusive, with high-voltage 2400 to 34500 Volts inclusive and low-voltage 208Y/120 to 4160 Volts inclusive. The fill gases used in these sealed dry-type power transformers are not explicitly defined. This standard does not apply to other types of transformers, such as those transformers described as exceptions in IEEE C57.12.01, as well as ventilated dry-type, non-ventilated dry-type, and liquid-immersed, and transformers.
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No Superseded Standards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No Inactive-Withdrawn Standards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.
No Inactive-Reserved Standards
