The external LPS is your building's primary shield. It consists of three integrated sub-systems: the air-termination system, the down-conductor system, and the earth-termination system. A. Air-Termination System
No. NFPA 780 is the US standard. While similar in concept, key differences exist in rolling sphere radii and material requirements. Always use the standard mandated by your local authority.
The air-termination system intercepts the lightning flash. The standard specifies three methods for positioning air-termination rods, conductors, or meshes:
: The grounding network that disperses the lightning current into the soil. 2. Lightning Protection Levels (LPL)
IEC 62305-3 outlines how to prevent these hazards through physical insulation (covering down-conductors with cross-linked polyethylene), physical barriers (fencing off down-conductor zones), or grounding mesh grids that equalize surface voltage. 6. Maintenance and Inspection
No. IEC does not sell individual clauses. You must purchase the complete document.
: Before designing an LPS, it's essential to assess the risk of a lightning strike. This involves evaluating factors like the location of the structure, the type of structure, and the potential consequences of a lightning strike.
