Abstract
- This paper proposes an analytical formula for calculating lightning-induced voltages on an infinitely long overhead line generated by a lightning stroke departing from an arbitrary altitude. A calculation method of the lightning-induced voltages to consider various engineering return-stroke models that can account for the variation of both current amplitude and velocity in a lightning channel is proposed. The lightning stroke is divided into a number of segments, and the analytical formula of the lightning-induced voltage is applied to each segment. This paper discusses the influence of parameters of return-stroke models on lightning-induced voltages. The proposed method is applied to a case of lightning strike to a tall stack.
