To validate this technique, fifteen NCI were aged in a salt fog chamber by applying nonstandard methods. Before ageing the NCI, the electric field distribution along each insulator was measured (sound field curve). When an insulator flashed over during the ageing test, the insulator was removed from the salt fog chamber and its electric field distribution was again measured (aged field curve). All the insulators that flashed over had visible defects and showed an electric field distribution different to that initially obtained. The comparison between the sound field and aged field curves for these insulators validated the location of the defects along the insulator. On the other hand, the electric field distribution measured on insulators which had no visible defects was similar to that initially obtained. This means that for these cases the flashover was only caused by the pollution phenomenon, and not by any defect furthermore, the electric field distribution measurements on all the insulators at the middle and at the end of the ageing test were performed, in order to mainly determine if some internal defect in the insulators, without visible defects, had occurred. According to the results, no-defects were found in the insulators without visible defects, being as their aged field curves equaled their sound field curves. It is concluded that this diagnostic technique may be used in service to evaluate the performance of non-ceramic insulators if the measurement methodology is systematically applied and the electric field detector is used in a proper way. The insulators that did not suffer damage during the ageing test show a good correspondence between the electric field curves measured before and after ageing.","PeriodicalId":342687,"journal":{"name":"Conference Record of the 2004 IEEE International Symposium on Electrical Insulation","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126119402","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}
