Efficient PEEC Computation of Losses and Currents in Screens of Round Wires in Submarine Tripolar Cables

Abstract

<div>A PEEC formulation is applied to compute Joule losses and currents in the wires composing the screens of the phase conductors in a submarine tripolar cable. In order to model the infinite extent of the cable and to reduce the computational burden, simmetries of the geometry are exploited. A good agreement is obtained with brute force FEM simulations, with a dramatic reduction of computational times and memory requirement.</div>
