IEEE C57.19.00-1991

This standard applies to outdoor power apparatus bushings that have basic impulse insulation levels of 110 kV and above for use as components of oil-filled transformers, oil-filled reactors, and oil circuit breakers. This standard does not apply to the following: (1) High-voltage cable terminations (potheads); (2) Bushings for instrument transformers; (3) Bushings for test transformers; (4) Bushings in which the internal insulation is provided by a gas; (5) Bushings applied with gaseous insulation (other than air at atmospheric pressure) external to the bushing; (6) Bushings for distribution-class circuit breakers and transformers; (7) Bushings for automatic circuit reclosures and line sectionalizers; (8) Bushings for oil-less and oil-poor apparatus

This standard defines the special terms used, service conditions, rating, general requirements, and test procedure for outdoor apparatus bushings. See IEEE C57.19.01-1991 for specific listings of values of electrical and mechanical characteristics, dimensions, and other related requirements that are defined or described in this standard.

Revision Standard - Superseded. Service conditions, rating, general requirements, and test procedures for outdoor apparatus bushings are set forth. They apply to outdoor power apparatus bushings that have basic impulse insulation levels of 110 kV and above for use as components of oil-filled transformers, oil-filled reactors, and oil circuit breakers. The following are not covered: high-voltage-cable terminations (potheads), bushings for instrument transformers, bushings for test transformers, bushings in which the internal insulation is provided by a gas, bushings applied with gaseous insulation (other than air at atmospheric pressure) external to the bushing, bushings for distribution-class circuit breakers and transformers, bushings for automatic circuit reclosures and line sectionalizers, and bushings for oil-less and oil-poor apparatus.
