Underground Electric Transmission and Distribution for Light and Power - Tapa dura

Reseña del editor

The rapid growth of the electric light and power industry with the resultant increase in the number of overhead wires, has brought about the policy on the part of municipal authorities of compelling utility companies to operate their systems underground. This has led to the development of a more or less specialized branch of electrical engineering; it involves large expenditures annually and gives rise to operating difficulties in many cases not clearly understood by the central station engineer. While there are various treatises which deal with special branches quite fully, there appears to be no work which covers the general field of underground construction, transmission and distribution. The writing of this book was undertaken by the author because of repeated requests from engineers engaged in the construction and operation of underground systems, for information bearing on many of the details of this branch of central station work. In the preparation of this volume, the author has not included such data as can readily be obtained from handbooks. The treatment of the subject assumes on the part of the reader a general knowledge of the fundamentals of electrical theory. The subject matter has been treated from the American point of view, since European practice differs considerably from that followed in A merica, due to the difference in conditions under which electric lighting properties are operated. A part of the material contained in this volume originally appeared in the various reports of theN ational Electric Light Association Committee on Underground Construction, on which committee the author has served for the past five years, and acknowledgment is hereby made to the Association for permission to use data from these reports.
