This paper proposes a novel method for calculation of frequency dependent parameters for any arbitrary shaped cable based on a new integral equations formulation and its Method of Moment solution. The proposed approach accurately considers both skin and proximity effects. The computation of series impedance matrix using this method is described for a sector-shaped cable example. The frequency domain impedance calculations are compared with alternative techniques such as finite element and sub-conductor methods. Time domain simulation results for open and short circuit terminations are also compared with sub-conductor technique.
