THE GENERATING, TRANSMISSION AND DISTRIBUTION SYSTEMS OF THE EDISON ELECTRIC COMPANY OF LOS ANGELES, by George P. Low, 1903

"Of all the world, America is infinitely far in the lead in the practical applications of transmission engineering, and of all America, California shows greater development along this line than any other State in the Union, yet nowhere in California is there to be found more interesting long distance high voltage work of almost every conceivable description than exists in the southern portion of the State, where in a single system of The Edison Electric Company, of Los Angeles, alone may be marked not only the first polyphase transmission station ever built for commercial service in America, but where also may be traced, step by step, every advance made in the art of electric power transmission down to the present time."
