Abstract:Insulation-related accidents of gas-insulated switchgear, induced by very fast transient overvoltage, have become increasingly serious in high-voltage power systems. A steep-fronted impulse voltage test equipment is developed for studying the discharge characteristics and mechanisms in the SF 6 gap. The influence of the electrode radius on the breakdown characteristic of a fixed-distance SF 6 gap is studied. It is found that discharge behaviors of the SF 6 gap show the so-called critical radius effect. With de… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
