It is shown that significant loss reduction and improvement in voltage distortion levels can be achieved when taking harmonic components into account.<<ETX>>","PeriodicalId":171461,"journal":{"name":"Conference on Industrial and Commercial Power Systems","volume":"36 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130550748","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}
