Présentation de l'éditeur
In the following pages an attempt is made to famish the reader with a general account of the principles, construction, and use of alternatecurrent measuring instruments, generators, motors, and transforming machinery. Special attention is devoted to methods of testing. The first three chapters contain a sketch of alternate-current theory. The author has tried, as far as possible, to exclude everything of purely academic or historical interest; on the other hand, he has not hesitated to devote a good deal of space to matters which are either not generally understood, or which are of too recent origin to have found their way into many text-books. The author desires to express his indebtedness to the various firms who supplied him with working drawings and placed other information at his disposal; especially would he like to mention in this connection The Electric Construction Co., Ltd.; Messrs. Everett, Edgcumbe and Co.; Messrs. Kelvin and James White, Ltd.; and Messrs. Nalder Bros, and Thompson, Ltd. The bulk of the illustrations have been specially prepared for this book. A. H. London, N.W., Oddber,
