Abstract

This paper presents an analysis of the proximity effect in a line consisting of two identical solid conductors of circular cross section. Integral equation for the current distribution in one of the conductors is solved approximately by assuming the current density in the form of a finite double polynomial series and by applying the point matching procedure. The current distribution obtained by the presented method has been checked by implementing the FEMM 4.0 software package. Also, the a.c. to d.c. resistance ratio is calculated and the results are compared to the available ones, and a good agreement is exhibited.
