2D BEM Computation of Power Losses in Multiple Thin Conductive Shields

Abstract

This paper proposes a method to calculate Joule and hysteresis losses of thin conductive and magnetic shields in two dimensions. A known BEM formulation enforcing the Thin Layer Impedance Boundary Conditions (TLIBCs) is extended to problems involving multiple closed shields. Analytical formulae for the losses are derived. A typical geometry of shields for a three-phase conductor system is used to show that a good accuracy can be achieved.
