The apple grove 750 kV project statistical analysis of audible noise performance of conductors at 775 kV

Abstract

This paper presents the results of a statistical anaylsis of conductor corona generated audible noise as measured at the Apple Grove 750 kV Test Project, a joint field investigation sponsored by the American Electric Power Service Corporation and the Westinghouse Electric Corporation. A comparison of simultaneous audible noise data is made on three sizes of four conductor bundles [diameter of 1.382 in. (35.1 mm), 1.196 in. (30.4 mm), 1.0 in. (25.4 mm)]. Also a correlation is given of simultaneous readings of audible noise, radio noise and corona loss. Copyright © 1974 by The Institute of Electrical and Electronics Engineers, Inc.
