6. Lightning Protection Zones (LPZ) · Page 1 of 6
LPZ Concept Overview
Create nested zones with decreasing electromagnetic stress.
Zone idea
Lightning Protection Zones (LPZ) describe volumes where the lightning electromagnetic environment is controlled. Each boundary can include shielding and SPDs.
Typical zones
- LPZ 0A / 0B: outside, direct strike possible / not possible
- LPZ 1: inside after first bonding/SPD boundary
- LPZ 2+: further protected volumes for sensitive electronics
Design goal
Reduce surge current and field strength step by step toward critical loads.
