Calculation of electric field and audible noise from transmission lines with non-parallel conductors

In order to investigate the feasibility of using new transmission line configurations with nonparallel conductors, for managing magnetic field in critical areas, techniques are needed to assess the effects of different three-dimensional line arrangements on other important design parameters. A new method for calculation of electric field and corona-generated audible noise from nonparallel conductors is described and implemented as a computer tool. This method uses linearly varying line charges to simulate charge distribution along the axial direction of the transmission line. New algorithms are developed for calculating electric field and audible noise due to nonuniform line charges and illustrated by examples of low magnetic field transmission line designs.
