Excerpt from Protective Relays: Their Theory, Design, and Practical Operation
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 author's 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. Q Consequently, many reliable sources Of information were 5; freely consulted and in several instances, passages were quoted El verbatim from a booklet entitled Performance Of Instrument Transformers and from Protective Relays which in turn was reprinted from an article by Mr. L. N. Crichton in The Electric Journal. Full credit is hereby given to the Westing house Electric Manufacturing Company for such excerpts; also to the American Institute Of Electrical Engineers for several paragraphs quoted from its June, 1919, Proceedings.

Paperback. Condición: New. Print on Demand. This book delves into the intricate world of protective relays, essential devices safeguarding electrical systems from disruptions and damage. The author traces the evolution of these devices, from their rudimentary beginnings as simple fuses to the sophisticated relays of the early 20th century. Exploring the fundamental principles of operation, the book delves into various relay types, including plunger, power-directional, and induction relays, elucidating their functions and applications in diverse scenarios. It meticulously examines the intricacies of trip circuits and time delays, crucial aspects of relay operation that ensure timely responses to electrical abnormalities. Beyond relay mechanics, the book provides invaluable insights into the broader context of electrical protection, encompassing circuit breakers, instrument transformers, and the identification of faults within electrical systems. With its comprehensive coverage of both theory and practical applications, this book serves as an indispensable resource for engineers, technicians, and anyone involved in the operation and maintenance of electrical power systems. The book's insights illuminate the critical role of protective relays in maintaining the stability and reliability of electrical infrastructure, underscoring their significance in a world increasingly reliant on electricity. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
