The function of a lightning protection system is to protect structures from fire or mechanical destruction and to prevent that persons in buildings are injured or even killed. An overall lightning protection system consists of external lightning protection (lightning protection/earthing) and internal lightning protection (surge protection)
LIGHTING PROTECTION SYSTEMS
- Interception of direct lightning strikes via an air-termination system
- Safe discharge of lightning current to earth via a down-conductor system
- Distribution of the lightning current in the ground via an earth-termination system
- Prevention of dangerous sparking in the structure by establishing equipotential bonding or keeping a separation distance between the LPS components and other electrically conducting elements
According to the EN/IEC 62305 standard, a lightning protection system consists of the following elements:
- Air-termination system
- Down conductor
- Earth-termination system
- Separation distances
- Lightning equipotential bonding
