Lightning Strike EMP Effect On Local Grids

Electric fields generated by lightning strikes are analysed and compared with effects of a high altitude nuclear weapon detonation electromagnetic pulse scenarios. The decay in amplitude of electric fields generated by a intermediate level lightning strike is calculated over distance and further analysed in a full real world simulation of a severe lightning strike event within close proximity of a isolated residential grid. Factors influencing the immunity of the grid to electromagnetic pulses are simulated and discussed as well as induced voltages on conductors.
