Calculation and Character Analysis of Electromagnetic Field of Lightning Return Stroke in Near-field on the Surface of Ground
摘要
Abstract
In order to reveal the inherent relationship between the electromagnetic field of return stroke and channel-base current, we searched the derivative of electromagnetic field of lightning return stroke in near-field on the surface of ground and derivative of channel-base current of lightning return stroke from theory with transmission line (TL) model in this papper. The results by accurately calculating with a dipole method show that the waveform of the derivative of the electric field and waveform of the derivative of approximate calculation are consistent within 50 meters far from lightning return stroke channel; and the waveform of the derivative of the magnetic field and the waveform of the derivative of approximate calculation are consistent within 200 meters. The result concludes that the waveform of the derivative of electromagnetic field near lightning return stroke channel on the surface of ground is similar with waveform of the derivative of channel-base current of lightning return stroke.关键词
