| Abstract | The evaluation of the ground fault current distribution among the interconnected grounding systems in HV networks, appears very difficult because of the meshed structure of these networks and the presence of different sources involved in the fault. The study of a system made by only one line supplying the fault has been faced in two ways: using the circuital method or the decoupled method. The works available on this topic however lack in living a general procedure for facing the most common case of more complex systems. In the present paper the authors give a personal contribution for a methodical and accurate analysis of such complex systems, by providing an evolution of the circuital method able to solve the case of a system in which more than one line supply the fault. |
