Paperback. Condition: New. Print on Demand. This book provides direct solutions for rapid and accurate calculation of transmission lines for distribution of currents by means of overhead, underground, and interior wires in the areas of light, power, and traction. It was written to fill a void in the field and establish a direct solution to replace the trial method that was previously a necessary evil. The arrangement of formulas, tables, and text was dictated solely by the needs of the rapid worker, and the sections include the important effects of temperature and specific conductivity. The author presents new and original methods that determine the size of wire directly from the volt loss in the line, and also possesses unique features of scope, accuracy, and simplicity. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Seller Inventory # 9781333600969_0
