Monopolar Corona on Bundle Conductors

Abstract

In this paper, the monopolar corona equation is solved for bundle conductor using a modified iterative procedure to give the corona current contributed by each subconductor of the bundle. Some of the main underlying assumptions are waived in the present calculations. The variation of ion mobility with its life time as well as the change of corona onset voltage from point to point on each subgonductor ore taken into account for the first time. The calculated corona currents from each subconduotor are compared with those measured experimentally for a laboratory model.
