AN INTRODUCTION TO HIGH VOLTAGE ENGINEERING

AN INTRODUCTION TO HIGH VOLTAGE ENGINEERING PDF Author: SUBIR RAY

ISBN: 812032417X
Category : Technology & Engineering
Languages : en
Pages : 245

Book Description
This concise textbook is intended for undergraduate students of electrical engineering offering a course in high voltage engineering. Written in an easy-to-understand style, the text acquaints students with the physical phenomena and technical problems associated with high voltages in power systems. A complete quantitative description of the topics in high voltage engineering is difficult because of the statistical nature of the electrical breakdown phenomena in insulators. With this in mind, this book has been written to provide a basic treatment of high voltage engineering qualitatively, and wherever necessary quantitatively. Special emphasis has been laid on breakdown mechanisms in gaseous dielectrics as it helps students gain a sound conceptual base for appreciating high voltage problems. The origin and nature of lightning and switching overvoltages occurring in power systems have been explained and illustrated with practical observations. Protection of high voltage insulation against such overvoltages has also been discussed lucidly. Concept of modern digital methods of high voltage testing of insulators, transformers, and cables has been explained. Solved problems help students develop a critical appreciation of the concepts discussed. End-of-chapter questions enable students to obtain a more in-depth understanding of the key concepts.

Pages : 274

Book Description
A behind-the-scenes look at the robustly competitive race to dominate the market for electric cars, the larger-than-life moguls behind them, and the changes that are transforming the auto industry In the 1980s, it was unimaginable that the home computer would become as common and easy to use as a toaster. Today, plug-in charging stations and smart grids seem like something still far off in the future. But by 2020, the auto industry will look very different from today's field of troubled auto giants. The combination of technological breakthroughs and charging networks driven by global warming and peak oil makes it clear that revolutionary change in the auto industry is happening right now. In High Voltage, Jim Motavalli captures this period of unprecedented change, documenting the evolution from internal combustion engines to electric power. Driven by the auto world's ambitious and sometimes outlandish personalities, the book chronicles the race to dominate the market, focusing on big players like Tesla and Fisker, as well as a tiny start-up and a battery supplier. Flashing forward to the changes we'll see in the coming years, High Voltage shows a not-so-distant future where we will live on a smart grid, our cars "fueling," that is, charging, while we shop or sleep. The ramifications of these changes will be on a grander scale than most of us ever imagined—altering foreign policy, reducing trade deficits, and perhaps even ending global warming.

Possible Health Effects of Exposure to Residential Electric and Magnetic Fields

Possible Health Effects of Exposure to Residential Electric and Magnetic Fields PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309054478
Category : Science
Languages : en
Pages : 379

Book Description
Can the electric and magnetic fields (EMF) to which people are routinely exposed cause health effects? This volume assesses the data and draws conclusions about the consequences of human exposure to EMF. The committee examines what is known about three kinds of health effects associated with EMF: cancer, primarily childhood leukemia; reproduction and development; and neurobiological effects. This book provides a detailed discussion of hazard identification, dose-response assessment, exposure assessment, and risk characterization for each. Possible Health Effects of Exposure to Residential Electric and Magnetic Fields also discusses the tools available to measure exposure, common types of exposures, and what is known about the effects of exposure. The committee looks at correlations between EMF exposure and carcinogenesis, mutagenesis, neurobehavioral effects, reproductive and developmental effects, effects on melatonin and other neurochemicals, and effects on bone healing and stimulated cell growth.

Book Description
This book presents both the basic principles of high voltage science and deals with the practical application of this knowledge. The fusion of basic knowledge and practical usage has prompted the addition of subject areas to those already well known: a chapter on fieldgrading; a chapter on breakdown statistics; a section on tracing breakdown and; a method for checking tg δ- measurements. Blending basics and practice has also influenced the treatment of the topics. The author critically reviewed field calculations; studied combinations of dielectrics in a systematic way; related test specifications to insulation coordination and; critically reviewed discharge tests. Industrial High Voltage is published in two volumes and is divided into six fields. Volume I: Electric Fields: behavior and calculation; Dielectrics: breakdown mechanisms and applications; Constructions: combinations of dielectrics and field grading. Volume II: Co-ordination: deriving test specifications from insulation co-ordination; Testing: generating and measuring high voltages, statistics; Measuring: C, tg δ, partial discharges.
