Characteristics of electrical discharge evolving in an environment protected by a vertical rod

The work presented in this paper consists to determine the nature of the electrical discharge when it evolves in an environment protected by a vertical rod (playing the role of a lightning rod). To do this, we consider two cases: a purely conductive discharge and a resistive discharge. The comparison between these models and the electro geometrical model, universally used for the dimensioning of protections, reveals that the electrical discharge is purely conductive.
