This standard applies to power apparatus bushings that have basic impulse insulation levels of 110 kV and above for use as components of oil-filled transformers and oil-filled reactors. This standard does not apply to the following: -- High-voltage cable terminations (potheads) -- Bushings for oil circuit breakers -- 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 reclosers and line sectionalizers -- Bushings for oil-less and oil-poor apparatus -- Bushings for dc applications This standard defines the special terms used, service conditions, rating, general requirements, and test procedure for apparatus bushings. See IEEE Std C57.19.01™ for specific listings of values of electrical and mechanical characteristics, dimensions, and other related requirements that are defined or described in this standard.
