IEEE - PC57.12.01/D10
Draft Standard for General Requirements for Dry-Type Distribution and Power Transformers
|Publication Date:||1 July 2020|
This standard describes electrical and mechanical requirements of single and polyphase ventilated, non-ventilated, 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.1
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.
