THE ELECTRICAL TRANSMISSION OF ENERGY. A MANUAL FOR THE DESIGN OF ELECTRICAL CIRCUITS. BY ARTHUR VAUGHAN ABBOTT, C.E., MEMBER AMERICAN INSTITUTE OF FLECTRICAL ENGINEERS, MEMBER AMERICAN INSTITUTE CROSBY LOCKWOOD AND SON, TKE A2 1807 Entered according to Act of Congress in the year 1904, by In the office of the Librarian of Congress at Washington AMBORLIAD PREFACE. IT has been tritely remarked that "There is nothing new under the sun." In view of this sapient aphorism the reader will not expect to find much that is strange or remarkable in the present volume. Books, however, are something like kaleidoscopes, in which ideas, like the bits of colored glass, resolve themselves into innumerable stellate forms, presenting to the inspector picture after picture, each of seemingly different origin from the preceding ones. While investigating a subject, it has been the custom of the author to obtain all the works by different writers on the question under consideration, and to read them successively; thereby viewing the matter from a number of different standpoints. He has found this an exceedingly valuable way of acquiring information, and remembers with the liveliest sense of gratitude the various expositors from whose differing horizons he has scanned the landscape of complicated topics. The present volume has been prepared chiefly from the aspect of the author's experience, and is an endeavor to collect and arrange in an accessible and convenient form the data necessary to the scientific designing and proportioning of Electrical Circuits. No attempt has been made to describe any Central Station machinery; for the scope of the volume would not permit of an extension beyond the material relevant to the "Transmission of Energy," so aptly and untranslatably termed by the French "Canalisation." The opening chapters are devoted to an outline of Circuits, and to an annunciation of the principles and laws governing Conductors and Insulators. This is followed by a discussion of the methods of constructing Aerial Lines and description of Underground Conduits iii 287057 |
