IEC 62305-1 Ed. 3.0 b:2024 ✓ Most Recent

This part of IEC 62305 provides general principles for the protection of structures against lightning, including their installations and contents, as well as persons.

The following cases are outside the scope of this document:
– railway systems;
– vehicles, ships, aircraft, offshore installations;
– underground high-pressure pipelines;
– pipe, power and telecommunication lines separated from the structure;
– nuclear power plants.

The IEC 62305 series should be considered as a minimum requirement for these structures.

Until any further information by CIGRE is available the lightning current parameters described in this document can be applied also for offshore installations.

NOTE 1 In these cases, structures usually fall under special regulations produced by various specialized authorities. For structures (subsidiary or others) not falling under such special regulations, the IEC 62305 series still applies.

NOTE 2 Lightning protection of wind turbines is also covered by IEC 61400-24 [4].
