High Voltage Engineering Book By Jeraldin Ahila -- A Review

High voltage engineering is a branch of electrical engineering that deals with the generation, transmission, distribution, and application of high voltages and currents. It is essential for the design and operation of power systems, electrical machines, transformers, switchgear, insulation, and lightning protection. High voltage engineering also involves the study of phenomena such as electric fields, breakdown mechanisms, corona, sparks, arcs, and surges.

One of the books that covers this topic in a comprehensive and systematic way is High Voltage Engineering by M.Jeraldin Ahila. This book is based on the syllabus of Anna University for the seventh semester of electrical engineering students. It follows the course code EE8701 and covers all the units prescribed by the university. The book is published by Suchitra Publications and is available for purchase online.

The book consists of eight chapters that cover the following topics:

  • Chapter 1: Introduction to High Voltage Engineering - This chapter gives an overview of the history, applications, and challenges of high voltage engineering. It also introduces some basic concepts such as electric field intensity, potential gradient, electric flux density, permittivity, and capacitance.

  • Chapter 2: Electric Field Theory - This chapter explains the mathematical methods for solving electric field problems using Laplace's equation, Poisson's equation, boundary conditions, and numerical techniques. It also discusses the methods for calculating electric field stress and electric field distribution in various geometries.

  • Chapter 3: Breakdown Mechanisms - This chapter describes the different types of breakdown mechanisms that occur in different media such as gases, liquids, solids, and composite materials. It also explains the factors that influence the breakdown strength and the methods for measuring it.

  • Chapter 4: Generation and Measurement of High Voltages - This chapter presents the various methods for generating high direct current (DC), alternating current (AC), impulse, and harmonic voltages using transformers, rectifiers, capacitors, Marx generators, impulse generators, and resonant circuits. It also discusses the various instruments and techniques for measuring high voltages such as sphere gaps, potential dividers, peak voltmeters, oscilloscopes, and digital recorders.

  • Chapter 5: Electrical Breakdown in Gases - This chapter explains the theory and characteristics of electrical breakdown in gases such as air, nitrogen, sulfur hexafluoride (SF6), and vacuum. It also covers the topics of corona discharge, partial discharge, spark discharge, arc discharge, and gas insulated systems.

  • Chapter 6: Electrical Breakdown in Liquids - This chapter describes the theory and characteristics of electrical breakdown in liquids such as mineral oil, synthetic oil, water, and liquid nitrogen. It also covers the topics of electrohydrodynamic phenomena, cavitation phenomena, streamer theory, bubble theory, and liquid dielectrics.

  • Chapter 7: Electrical Breakdown in Solids - This chapter discusses the theory and characteristics of electrical breakdown in solids such as paper, mica, rubber, ceramics, glass, plastics, and polymers. It also covers the topics of intrinsic breakdown, thermal breakdown, electromechanical breakdown, electrochemical breakdown, partial discharge phenomena, aging phenomena, and solid dielectrics.

  • Chapter 8: High Voltage Equipment Design and Testing - This chapter provides an overview of the design principles and testing procedures for high voltage equipment such as transformers, bushings, insulators, cables, circuit breakers, surge arresters, and lightning protection systems.

The book is written in a clear and concise manner with numerous examples, diagrams, tables, and illustrations to aid the understanding of the concepts. The book also includes review questions, objective questions, numerical problems, and model question papers at the end of each chapter to help the students prepare for their examinations. The book is suitable for both undergraduate and postgraduate students as well as professionals and researchers in the field of high voltage engineering.

In conclusion, High Voltage Engineering by M.Jeraldin Ahila is a comprehensive and systematic book that covers all the aspects of high voltage engineering in a simple and lucid way. It is a valuable resource for anyone who wants to learn more about this fascinating and challenging field.
