There has long been need for a comprehensive work dealing exclusively with the design, construction, and performance of lines for the transmission of electric power, in which the material is so presented that it will be useful to those who are interested in the subject, from beginners to more advanced engineers. The subject matter pertains to the design, construction and performance of transmission lines, and for all practical purposes, is compiled to cover the subject in that sequence. It comprises a step-by-step procedure from short-line problems requiring only the simplest of arithmetic, through long high-voltage line problems requiring involved mathematics for their solution.
The method of presentation is largely new. The equations in Chap. IV for finding the economical size of a.c.s.r. and copper-weld-copper, as well as the new method for calculating sag in long spans (mean length method) in Chap. IX, were developed by the author and have not previously been published. The critical load (Chap. XV) is treated from a practical operating point of view and should be of considerable interest and value to operating engineers. In the application of the hyperbolic theory of solution, an attempt has been made to simplify the work and offer such explanations as will serve to promote more extensive use of this method of analysis. This material should be of special interest to more advanced practicing engineers and to teachers in schools of engineering. It should also provide incentive for those who are not familiar with the method to learn more about it.
The book contains several numerical examples, accompanied by their solution, which should serve as an aid in the application of the theories and methods employed.
Approximately one-third of the book, comprising Chaps. X to XIII, is devoted to field work or work closely related thereto, covering line location and survey; modern devices, tools, and equipment; and successful methods of transmission-line construction. This material is suitable for use by construction men, contractors, and others engaged in this line of work.
