The design of an LPS depends on the Lightning Protection Level (I, II, III, or IV).

Context and purpose Lightning poses two principal classes of hazard to structures and occupants: (1) direct strikes causing mechanical damage and fire, and (2) indirect effects (e.g., side flashes, fire from conductive paths, or explosive effects when lightning currents flow through metallic or fluid-filled systems). IEC 62305-3 aims to quantify the risk from these hazards and set out prescriptive and performance-based measures to mitigate them. The standard is used by designers, engineers, insurers, and safety regulators worldwide to justify protection schemes and meet liability and safety obligations. iec 62305-3 pdf

This classification is crucial because it dictates the geometry of your protection. The design of an LPS depends on the

To remain compliant, systems must undergo regular inspection and testing as outlined in the standard. The standard is used by designers, engineers, insurers,
