Resumen

This paper studies the phenomenon of lightning strikes in transmission lines located in areas with high resistivity and isoceraunic level, analyzing two cases: with and without Transmission Line Arresters (TLA) installed. In order to demonstrate the behavior of TLA as protection against lightning strikes, a sector of a 220kV double-circuit transmission line was taken, which has high ground resistivity and will be simulated in ATPDraw with lightning impulse discharges between 10 - 100 kA with normalized wave front 1.2/50 μs. Finally, the scope was obtained to carry out the strategic installation of TLAs that allow efficient mitigation of disconnections due to backflashover.
