Abstract :
A self consistent dynamic model enabling to determine the different characteristics of the negative lightning discharge and the return stroke is presented. This model takes into account the different phases of propagation (i.e., the initiation of the first corona, the pilot system, the negative and space leaders, the junction of leaders and the final jump). It uses LCR line electrical network parameters derived from electromagnetic field, physical laws and gas discharge theories. The simulated results are discussed with respect to experimental data reported in the literature.
