Abstract:In non-hermetically sealed medium voltage oil switchgear (MV OIS), insulating oil will absorb water from the ambient air. Humidity influenced by the acidity of the oil affects the breakdown voltage. Moreover, switching actions causes copper particles from the switching contacts to be released in the oil. To assess and consequently reduce the risk of failures due to breakdown of oil, parameters such as tan , acidity, aging times, copper particles content, etc. have been measured. It will be shown that while tan… 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.
