TL;DR: In this paper, the statistical data of the significant parameters of lightning flash, collected by many researchers over many years around the world, are presented, including peak current, waveshape and velocity of the return stroke, the total flash charge and /spl int/I/sup 2/dt.

TL;DR: In this paper, a multistory transmission tower model is proposed to predict the waveform of each insulator voltage, which is useful in determining the phase and the instant of a back flashover.

TL;DR: In this paper, an experimental investigation was performed on a UHV tower model for the EMTP multiconductor calculation of lightning overvoltage at substations associated with back-flashover at an adjacent transmission tower.

TL;DR: In this paper, the Numerical Electromagnetic Code (NEC-2) is applied to the electromagnetic analysis of tall structures hit by lightning, where a lightning channel is represented by a vertical conductor that is loaded by series inductance and resistance so as to simulate the slow propagation velocity of a current wave on the lossy channel.

TL;DR: In this paper, a numerical electromagnetic code was used to compute the tower surge response. But the code used in this paper is not the one based on the circuit theory such as the Electromagnetic Transients Program (EMTP), but the one that solves the electric field equations directly by the moment method.
