Abstract

A finite-element procedure is presented for calculation of the frequency-dependent resistances and inductances and of the capacitances of a multiconductor cable. The inductances and resistances are evaluated taking account of skin and proximity effects. The capacitances are obtained by integrating the Laplace equation. The procedure permits analysis of systems having extremely complex geometric configurations and also diverse insulating materials with different dielectric characteristics. The resistance, inductance, and capacitance values obtained agree with the values obtained, in simple cases, by an exact analytical solution
