NEN-EN-IEC 62305 (NEN 1014)
Lightning protection system (LPS)
Bliksembeveiligingsinstallatie (LPS)
Also known as: lps, bliksemafleider, nen-1014, iec-62305, lightning, lightning-protection, lightning-protection-system, lightning-arrester
Lightning protection system (LPS): External (air terminal + down conductors + earth electrode) plus internal (Type 1 SPD) system discharging direct and induced lightning energy to earth. NEN-EN-IEC 62305 divides buildings into 4 LPL classes (I-IV) based on risk analysis; mandatory for high buildings, schools, factories with explosion hazard.
Practical example
Lightning protection system (LPS). A school in LPL class III gets air terminals on the roof, two separate down conductors to a ring earth electrode, and a type-1 SPD in the main distribution board.
Common mistake
Lightning protection system (LPS). Common mistake: omitting Type 1 SPD in buildings with external LPS — without Type 1, a direct strike can still push the installation to arc-flash level.
