Abstract : The deleterious effects of lightning discharges due to inter/intra-cloud discharge on large distributed electronics installations (observed over a number of years) range from momentary disruption in performance to catastrophic destruction of site components. A model is developed which gives ground level electric field intensity. The effects of this electric field on overhead power lines, including the influence of the soil characteristics on the effect of the lightning electromagnetic pulse (LEMP) is presented. The results of voltages induced in long cables by LEMP on the components of the installation is also discussed. A history of implementation procedures for distributed electronic installation and methods of mitigating these results are presented. (Author)
