In particular they evaluate the performance of these devices taking into account the nonuniform distribution of the main physical quantities that affect the energy conversion (i.e. temperature, pressure, magnetic field and so on). In addition, the connection of MHD generators to high voltage AC lines is also analysed. The results of all simulations executed are shown and discussed.","PeriodicalId":176640,"journal":{"name":"1997 IEEE International Electric Machines and Drives Conference Record","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115179920","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}

The calculation method for transient electric field analysis inside a power transformer impressed with an impulse voltage is presented. Initially, the concentrated electric network for the power transformer is constructed by dividing the transformer windings into several blocks and by computing the electric circuit parameters. Next, a transient electric field analysis is performed. Using the results of the circuit analysis as boundary conditions, a 2-D axisymmetrical electric field finite element analysis is performed. Finally, an animated display technique for the transient voltage, the electric field intensity and the tolerance rate of electric field intensity distributions is proposed as an extremely useful tool for design on graded insulation. A successful application of the proposed method for analysis of a model transformer for which the computed results agree very well with measured results is also presented.","PeriodicalId":176640,"journal":{"name":"1997 IEEE International Electric Machines and Drives Conference Record","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123958321","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}
