Abstract :
A survey of the methods proposed in the literature to evaluate the effect of nearby lightning strokes on electric power transmission/distribution circuits is performed, describing the assumptions taken as well as the mathematical tools applied at each of the simulation stages of the physical phenomena. A comparison is made between the approaches proposed by Master & Uman [1984] and Chowdhury [1989] to describe the electromagnetic field associated with the atmospheric discharge. After validation, both methodologies are applied to the same reference problem. Results are presented and analyzed, reflecting interesting differences in the figures obtained by each of the approaches for the outage rates of the electric circuits, chosen as test cases, with a tendency of the method of Chowdhury to estimate higher
