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 hoise 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.
