Synopsis
Excerpt from Polyphase Electric Currents and Alternate-Current Motors
No apology is needed for devoting special attention at the present time to the subject of polyphase electric currents. There seems to be no doubt that in the problem of the electric transmission of power a very important part will, in the future, be played by alternating currents combined in systems of two or three different phases. Already a number of examples exist; and some very large works are now in course of construction. The undoubted advantages possessed by polyphase systems over either (a) continuous current systems, or (¿) ordinary single phase alternate currents, for the special service of power transmission, are beyond question; but it remains to be seen how far the complications thereby inevitably introduced are, in practice, sufficiently great to militate against polyphase distribution for the purpose of general electric lighting supplies.

Polyphase Electric Currents and Alternate-Current Motors (Classic Reprint)
impression à la demandeVendeur : Forgotten Books, London, Royaume-Uni
Évaluation du vendeur 5 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book delves into the fascinating world of polyphase electric currents and the alternate-current motors that utilize them. Written in a clear and concise style, suitable for both students and engineers, the book provides a comprehensive overview of this groundbreaking technology that revolutionized the field of power transmission in the late 19th century. The author examines the key components of polyphase systems, including the generators that produce these currents, the ways in which they are combined, and the properties of the rotating magnetic fields they create. The text explores the historical development of these systems, highlighting the pioneering work of individuals like Gramme and Gordon. The book goes on to analyze the structure and theory of polyphase motors, showcasing their unique capabilities, particularly their ability to self-start, unlike their single-phase counterparts. The author also delves into the concepts of impedance and reactance, essential for understanding the behavior of alternating currents in circuits. The insights offered in this book provide a valuable historical perspective on the evolution of electrical engineering and the emergence of polyphase systems, highlighting their significance in the development of efficient and powerful electrical machinery. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
