electromagnetic radiation from lightning return strokes to tall structures
The study of the interaction of lightning electromagnetic fields with electrical systems and the design of appropriate protection strategies are generally based on statistical distributions of the lightning current measured at the channel base using either instrumented towers or artificial initiation of lightning using rockets. Recent studies based both on numerical modeling and experimental ob...
متن کاملThe lightning striking distance—Revisited
First return stroke current waveforms measured by Berger [Methods and results of lightning records at Monte San Salvatore from 1963–1971 (in German), Bull. Schweiz. Elektrotech. ver. 63 (1972) 21403—21422] and Berger and Vogelsanger [Measurement and results of lightning records at Monte San Salvatore from 1955–1963 (in German), Bull. Schweiz. Elektrotech. ver. 56 (1965) 2–22] are used to estima...
متن کاملTall-Structure Lightning Return-Stroke Modelling
A lightning return-stroke model, based on the lightning return-stroke current derivative measured at the Toronto CN Tower is presented in this paper. A 3-section transmission line representation of the CN Tower along with the derivative of the modified Heidler function is used to simulate the measured current derivative signal. Reflections from major structural discontinuities of the CN Tower a...
متن کاملTransient Response of a Tall Object to Lightning
Experimental data showing the transient behavior of tall objects struck by lightning are reviewed. The influence of this transient behavior, illustrated by simple calculations, on measured lightning current and measured remote electromagnetic fields is discussed. The estimated equivalent impedance of the lightning channel at the time of the initial current peak is appreciably higher than the ch...
متن کاملInitial stage in lightning initiated from tall objects and in rocket- triggered lightning
[1] We examine the characteristics of the initial stage (IS) in object-initiated lightning derived from current measurements on the Gaisberg tower (100 m, Austria), the Peissenberg tower (160 m, Germany), and the Fukui chimney (200 m, Japan) and their counterparts in rocket-triggered lightning in Florida. All lightning events analyzed here effectively transported negative charge to ground. For ...
