Abstract
THE electric power engineer will find much in this book that will be of value to him. As electrical stations increase in size, the amount and the cost of the requisite switchgear increase very rapidly. Devices are required for protecting the machines and for protecting the distributing mains. The question often arises whether it is worth while to instal a very expensive protection device in order to protect a main, thus paying a heavy annual insurance, or to run the small risk of having the main broken down. Cable manufacturers naturally favour the latter alternative, whilst manufacturers of protective switchgear favour the former. The authors rightly point out that the psychological device of calling a piece of apparatus a “lightning arrester” alone ensures a market for it, even without the accompaniment of a “publicity campaign.” Many English engineers have had the temerity not to use them. It has to be remembered, however, that in Great Britain we rarely have severe thunderstorms. The British Electrical and Allied Industries Research Association is carrying out valuable researches on switchgear, and Mr. Wedmore's official work keeps him in close touch with the most modern developments. The book discusses the latest practice.
