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

Abstract

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.

“…A lightning protection system (LPS) consists ultimately of an air termination system (ATS) that overheads the topmost parts of the model, with down-conductors and an earth-termination system. For the protection standard selection, the IEC standard suggests the assessment of the risk mentioned in [22,23]. Four lightning protection levels (LPLs) for the assembly was realized to satisfy the desired LPL efficiency class.…”
