A Proposed Statistical Analysis on the Backflashover Voltage Surge Waves on a Transmission Line

A probabilistic model to analyze surge voltage waves on a transmission conductor caused by lightning, strokes striking a transmission line tower has been proposed. In this proposed model, a probability apace has been constructed. Based on the constructed probability space, random variables denoting the voltage peaks, time to crest, and time to half have been generated. To know the statistics of surge voltage waves, it suffices to find out the cumulative probability distributions of these random variables. A illustrative numerical example to find out out the distributions of the random variables has been carried out using the Electromagnetic Transient Program(EMTP).
