Abstract:In order to promote the flexibility about the selection of transmission corridor, DC gas insulated transmission line (GIL) can be utilized to substitute part of the overhead line or cable in special environment. Key factors that greatly threaten the insulation level of GIL are surface charge accumulation along the insulator surface and electric field distortion under DC voltage. In this paper, the cone-plane electrode assembly has been established to simulate the electric field distribution of the coaxial cyli… 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.
