IEEE C37.017

Description / Abstract: This standard is applicable to bushings intended for use in high-voltage circuit breakers and gas-insulated switchgear. These bushings are intended for indoor and outdoor use, operating on alternating current with a rated voltage greater than 1000 V and a frequency of 50 Hz or 60 Hz. These bushings are usually a part of an apparatus and tested according to the apparatus of which they form part. Insulators or bushings used as an element of metal-enclosed switchgear assemblies, or in reclosers, sectionalizers, or similar equipment, are not included in the scope of this document. This standard does not apply to the following:

a) High-voltage cable terminations

b) Bushings for instrument transformers

c) Bushings for test transformers

d) Bushings for power transformers

e) Bushings for oil-filled circuit breakers

f) Oil-filled bushings in general

Purpose

This standard defines the special terms used, service conditions, ratings, general requirements, test procedure, and acceptance criteria for these bushings.
