Induced Lightning Disturbances in Overhead Shielded Cables Modeling by Current Generators

In this work we study the coupling of a lightning wave with overhead shielded cables. This study allows us to deduce the currents and voltages induced across the ends of the cable directly. In our work, we propose to represent the electromagnetic excitation distributed along a cable located in a node (end or junction) generator. This approach will lead us to reduce the analysis of the coupling of an object illuminated by a lightning wave in a problem of an excited simultaneously by several generators disposed on all nodes of the cable. Currents and voltages induced on all nodes of the cable shall be deducted by simple resolution of a system of linear equations.
