摘要: A modeling procedure that permits calculation of lightning-induced voltages on overhead lines starting from the channel-base current is discussed. The makes use a coupling model already presented in literature, based transmission line theory, for field-to-overhead calculations. Both models are discussed and compared with experimental results. hypothesis perfect conducting ground, used to analyze induced an by nearby lightning return stroke striking point equidistant terminations, limits its validity determined. comparison shows peak value maximum front steepness calculated using other return-stroke differ. It also shown another power-lightning literature several authors may result less accurate estimation voltages. >
