Design of special lightning protection system for opened sites and structures under construction: Dangerous potentials avaliation and mitigation

This paper studies the effective lightning protection for workers in opened sites and mobilized in construction works focusing dangerous potentials developed when the lightning current is conducted to the grounding system throw natural or designed down-conductors. This issue has increased its importance due to the need of special lightning protection systems enabling the continuity of work in opened sites or in structures under construction even in alert of atmospheric discharge occurrence.
