Effects of lightning channel equivalent impedance on lightning performance of overhead transmission lines
TL;DR: In this paper, a simplified method for estimating the minimum lightning currents causing shielding failure flashover and backflashover of overhead transmission line insulation, as affected by lightning channel equivalent impedance, is introduced.

Estimation of the minimum shielding failure flashover current for first and subsequent lightning strokes to overhead transmission lines
TL;DR: In this paper, the minimum shielding failure current causing flashover of line insulation is highly dependent upon insulator string flashover modelling and, also, markedly higher than that calculated according to the relevant IEEE Std 1243-1997 simplified expression.

Closed-Form Expressions for the Estimation of the Minimum Backflashover Current of Overhead Transmission Lines
TL;DR: In this paper, the minimum back-flashover current (IBF) of typical overhead transmission lines is estimated through ATP-EMTP simulations considering the tower ground resistance and AC voltage phase angle as parameters.

Lightning attachment models and maximum shielding failure current of overhead transmission lines: implications in insulation coordination of substations
TL;DR: In this article, the maximum shielding failure current of overhead transmission lines is derived by employing several lightning attachment models in shielding analysis, and an application to typical 110 kV up to 1150 kV overhead transmission line is shown.

Statistical method for the evaluation of the lightning performance of overhead distribution lines
TL;DR: In this article, the authors proposed a statistical method for the estimation of the flashover rate of overhead distribution lines, implementing a recently introduced statistical lightning attachment model and the simplified coupling model suggested by the IEEE Std. 1410:2011.
