Abstract:Electrical trees initiated from defects in solid insulation are one of the main causes of cable insulation failure. Both the initiation and propagation of electrical trees are linked to PD activity in the free volume and interfaces between electrode, gaseous and solid dielectrics. This work investigates the potential of suppressing partial discharge (PD) during tree propagation by displacing air with a higher electron affinity gas. Epoxy resin samples with pre-existing trees were energized under 7 kVrms in atm… 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.
