Abstract:This paper analyses the impact of square wave pulse voltage deadtime on the partial discharge (PD) and the lifetime of turn‐to‐turn insulation. A bipolar repetitive pulse voltage with a deadtime of 0–10 μs is produced using double half‐bridge solid‐state switches having push–pull technology controlled by a field‐programmable gate array. The mechanism of the discharge process at rising and falling edges of the pulse voltage before and after deadtime is analysed in detail. The discharge amplitude and PD probabil… 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.
