EVANS who contributed transmission and to the preparation the original so greatly to the and distribution of electric power of edition of this book Preface to fourth edition Some thirty years ago a well-known by his physician to take a complete rest. During this period, as a diversion, he began to study transmission-line that came, in 1922, a book that was quickly recognized as a classic on the subject because it was simple, practical, useful. The man was William Nesbit; the book, “Electrical sion Circuits.” In the two succeeding decades power-transmission tremendously in complexity. Voltages were doubled, longer lines were built, interconnections became more extensive, knowledge of how to protect against lightning methods of calculating performances were adopted. grew the need for a new book on transmission lines, one of broader scope that would meet the new conditions, but retain the entirely practical viewpoint of its predecessor. Fourteen men, all connected with the Central Station Engineering Electric Corporation, undertook to produce such a book. All of these men worked daily on actual problems such as are considered here. With this background of experience and with the reputation Nesbit book as inspiration, they presented in January, 1942 the first edition of a book which they hoped would be useful to all concerned with electric-power transmission as a practical reference book, helpful in solving everyday problems. In 1943 a second edition was brought out in which two
