Abstract :
Lightning induces voltage on a horizontally suspended conductor due to electromagnetic field coupling. If the induced voltage is measured across a matched impedance at both ends, it may be possible to locate the distance and angle of incidence of the lightning. Researches on lightning induced voltages mainly focus on its effect to insulation across the conductor and ground. The situation is modeled in time domain, to plot the lightning distribution of a specific area of particular size. From the results, the relationship of induced voltages to the distance and angle of incidence of the cloud to ground lightning is to be presented. A thorough study on extracting information of each lightning incident parameters (i.e. distance and angle) from expected induced voltages is discussed. The model will be tested on a physical mock setup for its concept and applicability. The parameters obtained and actual parameters are to be compared and discussed.
