In this work we study the coupling of lightning induced voltages in Overhead Transmission Lines. The study is led directly in the time domain with hold in account the effect of a finite conductivity of the soil. After discretization by the method so-called FDTD (Finite Difference Time Domain) of the lines equations excited by a lightning wave and the application in every node of the network in current and voltage, we deduct a equations system, of which the resolution permits us to deduct the induced electric quantities in every node of the network.. In order to confirm our theoretical work, we present a set of applications that allows validating this study. (C) 2014 Elsevier Ltd.
