Abstract

The field test project for studying corona, radio influence, and other technical features of electric power transmission in the extra-high-voltage range now has been in progress on The Ohio Power Company system of the American Gas and Electric Company at Brilliant, Ohio, for over two years. This paper is a progress report of this activity. It presents problems that are unique in the study of corona, particularly the effects of the conductor surface and weather upon the corona loss. It emphasizes the importance of foul weather in determining the average loss for use in evaluating the economic aspects of corona loss. Extensive tests also have been made of the effects of corona upon radio communication services. Radio influence is probably the factor litmiting the choice of a satisfactory conductor for extra-high voltages.
