LIGHTNING RODS
Protection against lightning strike impacts by safely conducting the discharge current down to the earth connection system
Why is it important to install al lightning rod?
Consequences from direct lightning strike impacts are well known to be potentially catastrophic in a physical as well as in an economical sense. They do therefore pose a severe thread to people, animals and structures of every kind.
The assessment of whether a structure should be equipped with a Lightning Protection System does ultimately depend on factors such as the Isokeraunic Level (lightning stroke density per surface unit and per year) and the type of risk and damages involved regarding people, animals, service continuity, structures, etc.
For a Lightning Protection System to be efficient in a global sense, it should comprise three kinds of protection:
• External protection against hazard of direct lightning strike impact
• Internal protection against conducted and inducted overvoltages
• Earthing system for dissipasion of lightning strike energy into the ground
Norms and Standards:
Norms and standards in the field of Lightning Protection do establish a range of factors that have to be taken into account when assessing the need for a protection system: isokeraunic level, exposed surface of the building, construction materials, type of usage of the building, etc.
· UNE 21186 & NFC 17-102 Norms
Both of the norms describe design matters regarding and practices that will lead to efficient protection of buildings, structures, open air areas, leisure areas, sport areas, etc... with active Early Streamer Emission based lightning rods.
