1.1
This Standard applies to single- and 3-phase dry-type transformers, including those with cast or resin encapsulated coils, that are within the limits of the electrical ratings listed in Clauses 7.2 and 7.3, and that are intended for use in accordance with the service conditions for dry-type transformers outlined in Annexes A and B.

Note: For information on the loading of dry-type transformers, see ANSI/IEEE C57.96.

1.2
This Standard deals with the standardization of voltage ratings, kVCA capacities, other electrical features, certain mechanical features, and test procedures.

1.3
This Standard does not apply to transformers designed solely for test purposes, rectifier transformers, welding transformers, furnace transformers, instrument transformers, motor-starting autotransformers, or any other special purpose transformers.

1.4
The word “transformer”, when used in this Standard, refers to a dry-type transformer unless otherwise specifically state
