Active Projects	Active PC57.12.01 - Standard for General Requirements for Dry-Type Distribution and Power Transformers 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.
Existing Standards	Superseded C57.12.01-1979 - American National Standard General Requirements for Dry-Type Distribution and Power Transformers Electrical, mechanical, and safety requirements of ventilated, nonventilated, and sealed dry-type distribution and power transformers or autotransformers, single and polyphase, with a voltage of 601 V or higher in the highest voltage winding, are described. Information that can be used as a basis for the establishment of performance, interchangeability, and safety requirements of equipment described, and for assistance in the proper selection of such equipment, is given.
