“…As the voltage across the tower structure rises, so does the voltage between the terminals of the insulator strings. In a simplified way, if this voltage reaches a critical level, a back-flashover arises [2]. Whenever a first back-flashover occurs, a fraction of the lightning current is injected to the faulted pole, and less current contributes to the voltage rise of the tower.…”

In this paper, an analysis study on parameters which affecting the backflash over pattern cause by lightning is done. A 132kV double circuit transmission line is modeled using ElectroMagnetic Transient Program EMTP software for backflash over simulation. A vertically configured double circuit transmission line can be modeled into several parts: towers, insulators, phase conductors, ground wire and tower footing resistance. The backflash over pattern is simulating by model the lightning current that hit the ground wire at the aim tower. The parameters that include in this study are the values of front, peak and tail of lightning current, striking distance and lastly the tower ground system. The pattern can also be analysis by taking into account the position of the phase conductors on the double circuit transmission tower.

“…Anderson [3], followed by Sargent and Daverniza [4], Darveniza et al [5], Bouquegneau et al [6] and many others, tried to solve the same problem using Monte-Carlo simulation techniques. Significant was also the study of Fisher et al [7], where measurements made on geometrical models of the Ohio Valley Electric Corporation's 345 kV transmission towers agreed well with the calculations of Lundholm et al [8], which have been based on the electromagnetic field theory and Maxwell's equations.…”
