This paper analyses the influence of wire-guard in distribution power systems subjected to a lightning surge. A real feeder was considered as a case study using ATP-EMTP software. The study compares the performance of the actual unprotected distribution line with a proposed shielded configuration. The simulation results show that the wire-guard can improve the immunity and power quality of distribution system against lightning.
