Revisiting lightning protection trends in the electric utility industry in the dawn of the new millennium

Abstract

We revisit some of the most significant aspects on lightning protection of transmission lines, trying to ascertain the fundamental concerns. We examine the concepts that were first involved in the definition of structure attractiveness. We then have a glance at the different electro geometrical (EGM) models and at how they evolved into more sophisticated models that try to explain the connection process between downward and upward streamers to complete the lightning discharge. We review literature to see the tendency on lightning protection of transmission lines in the new millennium.
