High Voltage and Electrical Insulation Engineering By Ravindra Arora

High Voltage and Electrical Insulation Engineering by Ravindra Arora and Wolfgang Mosch is a comprehensive textbook designed for graduate students, researchers, and professionals in the field. The book stands out for its unique approach of explaining the behavior of dielectrics based on the degree of uniformity of electric fields.

About the Authors

Ravindra Arora is a professor with an extensive background in electrical engineering. He obtained his doctorate from the Technische Universität Dresden (TU Dresden) in Germany and spent 34 years as a professor at the Indian Institute of Technology, Kanpur (IITK). At IITK, he established a high voltage laboratory and has been a leading researcher in the field of lightning phenomenon.

Wolfgang Mosch is a prominent professor and researcher from TU Dresden, where he has contributed significantly to the field of high-voltage technology. He and Professor Arora's collaboration brought a new, systematic approach to high voltage engineering to an international audience.

Key Content and Concepts

High Voltage and Electrical Insulation book provides a systematic and in-depth exploration of high-voltage insulation. Its core is the detailed analysis of how different types of dielectrics—gases, liquids, solids, and even vacuum—perform under various electric field conditions.

Classification of Electric Fields: A central theme is the classification of electric fields into uniform, weakly non-uniform, and extremely non-uniform fields. This classification helps in understanding and predicting the behavior of insulating materials and is a novel concept introduced by the authors.
Dielectric Materials: The book dedicates significant chapters to the behavior of different dielectrics, including:
- Gaseous Dielectrics: Discusses the properties of gases like air and sulfur hexafluoride ( $S F_{6}$ ), and the mechanisms of breakdown.
- Liquid Dielectrics: Examines the use of insulating oils in transformers and other equipment.
- Solid Dielectrics: Covers a wide range of solid insulating materials and their failure mechanisms, including a section on polymer insulators.
- Vacuum: Explores the unique dielectric properties of vacuum and its application in power circuit breakers.
Electric Stress and Breakdown: It delves into analytical and computational methods for estimating and controlling electric stress. It distinguishes between intrinsic and practical breakdown strengths and discusses factors that influence breakdown.
Overvoltages and Insulation Coordination: The text covers natural overvoltages, particularly those caused by lightning phenomenon, and the principles of insulation coordination to protect high-voltage power systems. It includes a brand-new approach to understanding lightning, including "ball lightning."
Condition Monitoring: The latest edition includes a new section on condition monitoring of electrical insulation, reflecting modern industry practices. This is crucial for assessing the health and remaining lifespan of high-voltage equipment.

High Voltage and Electrical Insulation book is well-regarded for its practical relevance, with numerous tables, figures, and diagrams to enhance understanding. It is considered an essential reference for engineers and a primary textbook for advanced courses in the field.
