To establish effective countermeasures on power facilities against lightning damage, it is necessary to clarify the lightning characteristics such as current parameters at the area of interest. In order to collect lightning current parameters effectively, the authors have observed electric and magnetic field waveforms simultaneously at south Kyushu, where the lightning flash density in summer is high. Based on observed electric field waveforms, the lightning current parameters have been estimated by adopting the Diendorfer-Uman model (DU model) as the returnstroke model. In this paper, the accuracy of the estimated return-stroke current waveform is verified by comparison with directly measured return-stroke current waveform, along with the accuracy of the estimated charge transfer from the electric field waveform measured with a slow antenna.

SUMMARYFor the effective and efficient insulation design of a power line, the return-stroke current waveform parameters are indispensable. Charge transfer is one of the important parameters when damage to equipment on a power line due to the energy of lightning is discussed. The amount of charge transfer associated with a lightning flash or individual strokes can be estimated by using the electric field change obtained with a slow antenna. The authors observed the electric field waveforms in south Kyushu for the purpose of efficient acquisition of return-stroke current parameters. In this paper, the authors discuss the relation between the negative first return-stroke current peaks and the impulse charge transfer based on the observed electric field waveforms. C⃝
