Book Description
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.

Book Description
The book presents basic theories of transformer operation, design principles and methods used in power transformer designing work, and includes limitation criteria, effective utilization of material, and calculation examples to enhance readers’ techniques of transformer design and testing. It includes: Core and winding commonly used, and their performances Insulation structures and materials, methods for improvements on dielectric strengths on partial discharge, breakdown and electrical creepage Losses and impedance calculations, major influential factors, and methods to minimize load loss Cooling design and the method to obtain effective cooling Short-circuit forces calculations, the ways to reduce the short-circuit forces, and measures to raise withstand abilities No-load and load-sound levels, the influential factors and trends, and abatement techniques In-depth discussion of an autotransformer’s special features, its stabilizing winding function, and its adequate size Tests and diagnostics The ways to optimize design are also discussed throughout the book as a goal to achieve best performances on economic design. The book contains great reference material for engineers, students, teachers, researchers and anyone in the field associated with power transformer design, manufacture, testing, application and service maintenance. It also provides a high level of detail to help future research and development maintain electrical power as a reliable and economical energy resource.

Book Description
A unique blend of traditional methods of electrical machine testing and modern approach to the subject is the key feature of the book. The book opens up with an introduction of the basic terms and deals with the tests conducted on transformers and induction machines as is needed by the undergraduate students of Electrical Engineering. A more realistic approach has been adopted to reach the bottom of the subject. A collection of nearly 140 questions gives in-depth understanding. An additional section on experimental values has also been provided. All the questions are provided with answers at the back of the book. A large number of pictorial presentations have been incorporated in the book in form of snaps, figures, circuit diagrams. Copyright (c) 2012 by Author & Designer. All rights reserved.
