During thes oscillations, transformer windings are subject to voltage stresses. For the analysis of such transient phenomena, lumped networks consisting of R, L, C parameters calculated from the geometric dimensions of transformer windings have been used. In this paper, a new method is described for modelling of transformer windings by their terminal impedance characteristics. It is shown that, by the use of the given models the transient oscillations occuring on the transformer windings can be examined through the state equations. Examples are given for a reduced scale model transformer and an industrial supply system.","PeriodicalId":188957,"journal":{"name":"1985 EIC 17th Electrical/Electronics Insulation Conference","volume":"130 40","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113939951","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}

For the last fifty years, the technology for electric motor repair in the united States has remained virtually unchanged. Nearly all of the electric motor repair companies have been and still are using the same machines and methods that were used when motors first came into existence. These methods have proven to be outdated, wasteful, time consuming and, in most instances, damaging to the electric motor laminations. In the last sixteen years, new technology has given birth to a whole new method of repairing electric motors.","PeriodicalId":188957,"journal":{"name":"1985 EIC 17th Electrical/Electronics Insulation Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130469193","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}
