Eddy current loss calculation in multiconductor systems

This paper presents the application of the finite element technique for calculating eddy current losses in multiconductor systems used in power transmission. This paper is a contribution to skin effect analysis in conductors and enclosures of arbitrary shapes. The distribution of the current density within each conductor is obtained from the magnetic vector potential and the total measureable current flowing in the conductor by a projective solution of the diffusion equation and Ampere´s law. Electrical parameters such as impedance per unit length are calculated from the loss density and stored magnetic energy and comparison between calculated and published data is presented.
