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.

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.File in questo prodotto:
