Abstract

In order to research the problems of electromagnetic compatibility (EMC) at electric power substations or electromagnetic interference generated by carrier channels on multi-conductor power transmission lines, the finite-difference time-domain (FDTD) method and multi-conductor transmission lines (MTLs) model can be used. But the impedance due to lossy soil is dependent on the frequency, so the problem is very complex. One new model to deal with it in the time-domain is proposed using Pade´s approximation. Contrasted with other methods, the model is accurate and can be used practically
