Audible noise generation of individual subconductors of transmission line conductor bundles

Audible noise duo to corona on high-voltage transmission line conductors can be reduced by introducing an asymmetry into the conductor bundle geometry. Predetermination of the optmum arrangement of conductors can be extremely involved and is best investigated by analyzing the performance of individual subconductors in the bundle. An experimental technique used for the determination of individual subconductor foul-weather noise generation is described. The results obtained allow one to compute the noise performance of any bundle configuration. Calculations are compared to the measured performances for two different bundle arrangememts.
