Download or read book Quality Confirmation Tests for Power Transformer Insulation Systems written by Behrooz Vahidi and published by Springer. This book was released on 2019-05-27 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on oil-paper insulation included in power transformers, especially for EHV and UHV transformers. The importance on insulation ever increased due to a growing voltage rating of transformers. Within the last decades, although research on the transformer insulation and diagnosis methods has advanced a lot, the insulation of HV transformers remained more or less unchanged. The book is divided into five chapters; the first and second chapters explain the basics of oil insulation, while the third chapter focuses on paper insulation. The final two chapters deal with the methods and outcome of testing both techniques. The primary target audience for this book is graduate students and power system engineers.
