Audible noise due to foul-weather corona on multi-conductor bundles for EHV and UHV transmission can be reduced by proper choice of the bundle geometry. Laboratory tests have been carried out to determine the noise generation of individual subconductor in a bundle. Based on the results of these tests, the relative audible-noise performance of several different con-figurations of 4-, 6-, and 8-conductor bundles are determined. A comparison is made between computed and measured performances for a 6-conductor bundle.
