Abstract

This document applies to outdoor and indoor bushings of any voltage used on DC systems, of capacitance graded or gas insulated types for use as components of oil-filled converter transformers and smoothing reactors, as well as air-to-air DC bushings. This document does not apply to the following: - cable terminations (potheads); - bushings for instrument transformers; - bushings for test power supplies; - bushings applied with gaseous insulation (other than air at atmospheric pressure) external to the bushing; - bushings for industrial application; - bushings for traction application; - bushings for distribution class transformers. This document makes reference to IEC 60137 for general terms and conditions and defines the special terms used, operating conditions, ratings, test procedures as well as general mechanical and electrical requirements for bushings for DC application.
