5、quipmentEnclosure Integrity. The Accredited Standards Committee on Transformers, Regulators, and Reactors, C57, has for a number of years been developing and correlating standards on these products. The data used in this work have been gathered from many sources, including the standards of the Insti
6、tute of Electrical and Electronics Engineers (IEEE) and the National Electrical Manufacturers Association (NEMA), reports of committees of the Edison Electric Institute (EEI), and others. This IEEE standard is a voluntary consensus standard. Its use becomes mandatory only when required by a duly con
7、stituted legal authority or when specified in a contractual relationship. To meet specialized needs and to allow innovation, specific changes are permissible when mutually determined by the user and the producer, provided such changes do not violate existing laws and are considered technically adequ
8、ate for the function intended. This standard was originally prepared by the Joint C57/C37 Working Group on Enclosures with Joseph Martin and then Robert C. Olen as chairmen. This group is now the Enclosure Integrity Working Group of the IEEE Transformers Committee. Notice to users Laws and regulatio
