Lightning is a natural phenomenon that has always fascinated humans. It is also a destructive force, and the science of protecting humans and their belongings on earth is called lightning protection. This book provides the reader with a thorough background in almost every aspect of lightning protection. The contents of the book, distributed over 23 chapters, covers all aspects of lightning protection including lightning parameters of engineering interest, the evaluation of the risk imposed by lightning strikes, the art of installing lightning protection systems on various structures, basic principles and procedures necessary to protect electronic equipment in buildings from lightning flashes, grounding in lightning protection, the function of surge protection devices, protection of power transmission lines and telecommunication towers from lightning, the interaction of lightning flashes with wind turbines, various aspects of lightning strikes to trees, medical and engineering aspects of lightning strikes to humans, and lightning warning systems. In addition to providing essential information on lightning protection for engineers and scientists, the book is intended for use as a textbook on lightning protection at both undergraduate and postgraduate level.

This updated and expanded new edition of Cooray's classic text provides the reader with a thorough background in almost every aspect of lightning and its impact on electrical and electronic equipment. The contents range from basic discharge processes in air through transient electromagnetic field generation and interaction with overhead lines and underground cables, to lightning protection and testing techniques. New to this edition are discussions of high-speed video recordings of lightning; rocket-and-wire triggered lightning experiments; tower initiated lightning discharges; upper atmospheric electrical discharges; attachment of lightning flashes to grounded structures; energetic radiation from thunderstorms and lightning; global lightning nitrogen oxides production; and lightning and global temperature change.

The Lightning Flash, 2nd Edition is a sound introduction to researchers and advanced students working in the field and of value for anyone designing, installing or commissioning equipment which needs to be secured against lightning strikes.

Lightning research is an interdisciplinary subject where several branches of engineering and physics converge. Lightning Electromagnetics is a book that caters for the needs of both physicists and engineers. It provides: The physicist with information on how to simulate: the charge generation in thunderclouds, different discharge processes in air that ultimately lead to a lightning flash, and the mechanism through which energetic radiation in the form of X-rays and Gamma rays are produced by lightning flashes; The power engineer with several numerical tools to study the interaction of lightning flashes with power transmission and distribution systems; The telecommunication engineer with numerical procedures with which to calculate the electromagnetic fields generated by lightning flashes and their interactions with overhead and underground telecommunication systems; The electromagnetic specialist with the basic theory necessary to simulate the propagation of lightning electromagnetic fields over the surface of the Earth; The atmospheric scientist with numerical procedures to quantify interactions between lightning flashes and the Earth's atmosphere, including the production of NOx by lightning flashes occurring in the atmosphere. This book also contains a chapter on the stimulation of visual phenomena in humans by electromagnetic fields of lightning flashes, which is essential reading for those who are interested in ball lightning.
