Abstract :
The effective application of carrier for reliability under all conditions of power system variabilities in operation and equipment requires precise knowledge of power system conditions and characteristics of terminal carrier equipment. New developments and practices, plus the continual complexing of transmission systems by additional paralleling circuits, line taps, etc., made it desirable to up-date a similar report written in 1948. A preliminary bibliography appears at the end of the paper under the heading of "References," but only 1 through 5 are mentioned in the text. All references apply to methods of measurement of carrier frequency properties of high-voltage lines and station equipment from 1940 to, and including, 1959.
