A comparison between beady wire and continuity failures is presented.","PeriodicalId":428411,"journal":{"name":"Proceedings of Electrical/Electronics Insulation Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115132523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many electrolytic solutions of different conductivities are tried. The effects of needle tip radius, electric field, and the time of voltage application are examined. The phenomena of WT are simulated and a computer model is developed, using the finite difference method. The experimental and simulated results show good agreement.
