Estimation of the maximal voltage induced on an overhead line due to the nearby lightning

Determination of the maximal voltages induced on the overhead power lines by nearby lightning stroke is a complex problem. The scope of this paper is to recognize the parameters that affect the maximal voltages and to present an equation for their estimation. This equation gives an opportunity to calculate the maximal voltage with the reasonable accuracy avoiding complex electromagnetic field calculus. It may be very useful in the estimation of flashover and outage rates due to the nearby strokes.
