It is also noted that there have been some transformers which have suffered a winding failure with no historical DGA overheating prior to failure via routine sampling, or violation of industry standard CO ppm values. This is not to say that overheating didn't occur prior to failure, but rather the last manual sample collected did not reveal any overheating and the problem seemed to develop so quickly that the outage came as a surprise to all. It is the intent of this paper to demonstrate a method utilizing the historical CO2/CO ratio in mineral oil filled transformers to help solve these puzzles and do it with greater accuracy than previously believed possible. By trending the CO2/CO ratio, the user will be able to qualify problems with heavy paper (such as a winding), light paper (such as a lead) and bare-metal connections (such as a De-Energized Tap Changer).","PeriodicalId":439228,"journal":{"name":"2017 IEEE 19th International Conference on Dielectric Liquids (ICDL)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133635453","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}

It is shown that the average AC breakdown voltage of JMEO is higher than that of mineral oil. Meanwhile it is similar under DC voltage. The statistical analysis shows that all large data groups (n>40) for AC and DC breakdown voltages of JMEO, MO and oil mixtures obey to the normal distribution law. This is proved using Shapiro-Wilk test, skewness and kurtosis values. It also observed that AC mean breakdown voltage of JMEO is higher than that of oils mixture (50%JMEO+50%MO) and MO, but it is similar with oils mixture (80%JMEO+20%MO). AC mean breakdown voltage of MO is the lowest one. DC mean breakdown voltages of JMEO, MO and oil mixtures (50%JMEO+50%MO) are similar. In contrast, DC mean breakdown voltage of oils mixture (80%JMEO+20%MO) is the highest one.","PeriodicalId":439228,"journal":{"name":"2017 IEEE 19th International Conference on Dielectric Liquids (ICDL)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115102525","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}
