In this paper we discuss how the inclusion of proximity effect influences the evaluation of the internal impedances of cylindrical conductors. After recalling the classical analytical formulation used for calculating internal impedance, we use a Finite Element Method (FEM) code, in order to take into account the proximity effect. We show that in a low voltage cable, at frequency higher than the industrial ones, and particularly above the kilohertz range, the impact of proximity effect is rather relevant and cannot be neglected when dealing with EMC issues related to cable networks.

Abstract

In this paper we discuss how the inclusion of proximity effect influences the evaluation of the internal impedances of cylindrical conductors. After recalling the classical analytical formulation used for calculating internal impedance, we use a Finite Element Method (FEM) code, in order to take into account the proximity effect. We show that in a low voltage cable, at frequency higher than the industrial ones, and particularly above the kilohertz range, the impact of proximity effect is rather relevant and cannot be neglected when dealing with EMC issues related to cable networks.
