A new model for non-uniform transmission lines

In this paper, a new multiconductor transmission line model for the simulation of electromagnetic transients, which takes into account non-uniform and frequency dependent electrical parameters, is presented. The proposed model is based on the method of characteristics and has the same mathematical form either for a single phase line or a multiconductor line. The results obtained using the proposed models are compared to results from the Numerical Laplace Transform (NLT) and the Alternative Transients Program (ATP).
