The Theory of Electric Cables and Networks

Abstract

WITH the rapid growth of electrical distribution, and the increasing size of networks, the most economical design of the distributing system is becoming more important every year. The third edition of Dr. Russell's well-known book will therefore be welcomed by all engineers who are concerned with cable manufacture or with the business of electric distribution. This edition does not differ very much from the second edition, which was published in 1919, nor is it necessary that it should, for the book deals mainly with fundamental principles. The tables of standard sizes of wires and cables and of the electrical and thermal constants of materials are of great value, and the discussion in the second chapter of the mechanical and electrical properties of copper is one of the most complete that is to be found in any standard text-book. Equally thorough is the study of insulativity and insulating materials. The treatment of distributing networks and the determination of the fault resistance of such networks is especially good. The author has himself contributed largely to the technical literature of this subject, and his method of finding fault resistance is well known to all distribution engineers.
