Synopsis

Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

Présentation de l'éditeur

In preparing a work of this nature, it will be realized that the subject is so broad and varied in its scope as to preclude an authors intimate personal knowledge of each and every system described. Attempt has been made to cover the subject from the first principles of Protective Relays to the protection of high tension net-works, the object being to make the work of value not only to the operator and tester who has a fair knowledge of electricity and is seeking more information, but also to the designer of the system who may find many points not previously taken into consideration in his calculations.

Some of this material has been published in the form of articles by the author in Power, Power Plant Engineering, Electrical Record and Southern Engineer, and thanks are hereby given to their editors for permission to use the text and electro-types for illustrations.
