Frequency Response Analysis (FRA) is a powerful diagnostic tool that offers deep insights into transformer health, though its interpretation presents significant challenges. This book introduces advanced techniques and intelligent methodologies for assessing transformer winding distortion and deformation through FRA. Drawing on extensive industry experience and academic research, it explores various methods for evaluating transformer winding conditions and presents in-depth analyses of fault mechanisms and failure modes from real-world data on over 80 power transformers. The causes, symptoms, and consequences of component failures are identified, offering valuable insights into transformer health. An advanced transformer modeling method is introduced to improve fault simulations, which can also be used for overvoltage prediction and transient analysis. Real-world case studies offer practical guidelines for interpreting FRA measurements, contributing to more accurate diagnostics and informed decision-making regarding transformer maintenance and replacement. This comprehensive resource serves as a valuable reference for professionals and researchers aiming to improve transformer reliability and optimize power system performance.

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.
