A numerical tool is developed and largely used in the design phase to optimize the divider performances with respect to frequency behavior and insulation strength. The divider, with a coupled matching stage, is laboratory characterized both at low and high voltage, taking into account the expected operating conditions. The estimated measurement uncertainty associated with its on-site use as a reference is within 550 ppm for the ratio error and 310 µrad for the phase displacement. Results of the first tests performed in MV/LV substations confirm that it can be effectively used in the calibration of medium voltage measurement transformers.","PeriodicalId":420824,"journal":{"name":"2011 IEEE International Workshop on Applied Measurements for Power Systems (AMPS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125704818","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}
