Abstract :
Recently, the lightning strokes to transmission lines are been watched more carefully due to the needs to improve the transmission lines performance and the power quality. The TLM (Transmission-Line-Model) numerical technique is applied to model a distribution line, surge arresters, grounding electrodes impedance time varying, and the connecting leads to ground. Two simulations are shown and compared with measurements.
