Abstract

The electric fields radiated by precursory pulses from triggered lightning experiments were carried out in this article. Preceding the initial stage, a total of 50 precursors are found span a duration of over 500 ms using a threshold of 50 A. The statistical summary of the precursory current pulses was presented. Two selected precursors were simulated and compared to the measured electric fields based on the extended guided-wave M-component model considering the presence of tall object on the ground. It is found that the late-time response of the electric fields at 110 m, which is mainly produced due to the presence of the wind turbine blade, generally agrees well with the measured data from the two precursors. Notable excursions of both initial negative and the following positive polarities are found through the simulated electric fields. The azimuthal magnetic fields are presented, as well as the sensitivity analysis about the electric and magnetic fields.
