Description

Revision Standard – Inactive – Superseded. Guidance on the use of outdoor power apparatus bushings is provided. The bushings are limited to those built in accordance with IEEE Std C57.19.00-1991. General information and recommendations for the application of power apparatus bushings, when incorporated as part of power transformers, power circuit breakers, and isolated-phase bus, are provided. An errata is available at http://standards.ieee.org/reading/ieee/updates/errata/C57.98-1993.pdf
