Electric Power Transmission: Principles and Calculations, Including a Revision of Overhead Electric Power Transmission (Classic Reprint)

When this book was published originally under the title Overhead Electric Power Transmission, its suitability for use as aC ollege text had not been seriously considered. It has, however, been used by a large number of technical schools and colleges, and while the restricted scope of the book may limit its suitability as a text for college students, the changes and additions which will be found in this new edition should, in the authors opinion, enhance its value as a college text without detracting from its usefulness in the field of practical engineering. The principal addition which has necessitated an alteration in the title is an entire chapter treating of Underground Conductors. This has been written with the kind assistance of Mr. C. J. Beaver who has not only furnished most of the data relating to underground cables, but has also read and criticised the matter presented inC hapter VII. A portion of the material which was originally contained in the Appendix has been incorporated in the text; but much of the first edition has been entirely omitted, either because its inclusion is no longer necessary owing to the rapid strides that have been made of late years in the general knowledge of electrical power transmission, or because it has been replaced by new material believed to be of more value to the student or practical engineer. The chapter describing the Thury system of transmission by continuous currents has been retained with only slight changes and additions. It has not been deemed expedient to omit this entirely because, although few American engineers have taken the trouble to familiarize themselves with this system of transmission, there are conditions under which it has certain indisputable advantages which European engineers have not been slow to recognize. The costs, both of material and labor, which are given inC hapter III, are not repres
