Method for Calculating of Lightning Impact Level on Overhead Transmission Line
Applied Sciences, 2021 This paper proposes a simple method for calculating the lightning impact level on overhead transmission power lines, taking into account its entire length. The method uses lightning historical data and the geographic coordinates of power line towers.
