For the effective and efficient insulation design of a power line, the return-stroke current waveform parameters are indispensable. A charge transfer is one of the important parameters when the damage to the equipments on a power line due to the energy of the lightning is discussed. The amount of a 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 observe 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.
