This paper presents preliminary results of the development of a computational tool based on the finite- difference time-domain method (FDTD), dedicated to investigate the lightning performance of electrical systems. The presented results, assuming homogeneous soil, were compared with measured experimental data and results obtained by an advanced electromagnetic modeling, and are in agreement in terms...
Lightning parameters measurement of the transmission lines is the foundation of lightning protection research. It plays an important role in supplying the original accurate data to study the lightning characteristics, analyzing the reason for lightning accidents, and designing the insulation of the transmission line. In this paper, the distribution of the lightning transient electromagnetic fields...
