Efficient Technique for 3-D Finite Element Analysis of Skin Effect in Current-Carrying Conductors

摘要

In this paper, an efficient method for the 3-D computation of steady-state skin effect problem in current-carrying conductors is presented. It is assumed that the total current is composed of the source current and eddy current and source current density is proportional to the electric field intensity. To calculate the source current density, the iterative procedure is employed. Hie proposed method can be easily implemented in the existing 3-D finite element code with slight modification. The proposed method is validated by comparison to known solutions of slot-embedded model and applied to the analysis of current distribution in vacuum interrupter.
