Modeling electromagnetic field radiated by Lightning coupling to overhead transmission lines

The major aim of our investigations is the computation of the voltages induced by an external transient electromagnetic excitation, especially due to the lightning discharge coupling to overhead transmission line networks. In this paper we propose a hybrid method for evaluating the electromagnetic field radiated by lightning The Agrawal et al. model coupling model will be used in order to analyse the lightning-induced disturbances in overhead transmission line networks.
