Resumen:
This paper presents a study about the infl uence of the wire-guard as a protection system in overhead distribution line in comparison with unprotected topology against lightning. A real feeder was considered as a case study using ATP-EMTP soft ware. Practical aspects related to the modeling of a distribution line are presented. Simulation results show that the shielding confi guration ensures a protection signifi cantly better than the actual topology, around 10 times in terms of lightning peak current. Thus, the wire-guard can improve the immunity of distribution system against atmospheric discharges.
