IEEE C57.94-1982 IEEE Recommended Practice for Installation, Application, Operation, and Maintenance of Dry-Type General Purpose Distribution and Power Transformers

standard by IEEE, 06/07/1982

Full Description

Scope

1.1 Transformers CoveredThis recommended practice covers general recommendations for the application, installation, operation and maintenance of single and polyphase dry-type general purpose, distribution, power, and auto-transformers of the following types:1) Ventilated, indoor and outdoor, self-cooled cooled or forced air cooled2) Nonventilated, indoor and outdoor, self-cooled or forced air cooled3) Sealed, indoor and outdoor, self-cooled1.2 Transformers Not CoveredThis recommended practice does not apply to the following:1) Instrument transformers2) Step voltage and induction voltage regulators3) Arc furnace transformers4) Rectifier transformers5) Specialty transformersNOTE -- Both ventilated and nonventilated transformers may be furnished with windings utilizing materials such as solid insulating material which allow or require different practices from those required in this recommended practice. In such equipment the recommendations in this recommended practice may be modified by specific manufacturer's recommendations.

Purpose

This recommended practice is intended for general use in the application, installation, operation, and maintenance of dry-type transformers manufactured in accordance with ANSI/IEEE C57.12.01-1979 [10]1, ANSI C57.12.50-1980 [2], ANSI C57.12.51-1981 [3], ANSI C57.12.52-1981 [4] and ANSI/NEMA ST 20-1972 [13]. Familiarity with other American National Standards applying to dry-type transformers and to their protection is assumed and the provisionsof those standards are indicated herein only for clarity.

Abstract

New IEEE Standard - Superseded.The application, installation, operation, and maintenance of single- and polyphase dry-type general purpose, distribution, power, and autotransformers are covered. The following types are included: ventilated, indoor and outdoor, self- or forced-air cooled; nonventilated, indoor and outdoor, self- or forced-air cooled; and sealed, indoor and outdoor, self-cooled. Instrument transformers, step voltage and induction-voltage regulators, arc furnace transformers, rectifier transformers, and specialty transformers are not covered.
