Abstract

The existence of a lightning detection monitoring system in industry is very necessary to avoid losses arising from return lightning strikes. The return stroke peak current is one of the most important measures of lightning intensity required in various fields of atmospheric electricity research. This can be estimated from the corresponding electric (E) or magnetic (B) radiation field peaks. The peak current of a lightning strike (I) is estimated from the peak electric field measured by an electric field antenna using a combination of the empirical formula of Rakov and the field-to-current conversion equation based on the transmission line model (Uman and McLain). Furthermore, the distance to the lightning location is obtained from the time difference between the electric field and the acoustic sensor signal. The new empirical formula, I=−0.66–0.028rE, is based on the combination of the two previous equations. Furthermore, historical lightning data is also displayed in the information system for further analysis.
