THE PROTECTION AREA
THE PROTECTION RADIUS (Rp) OF A PREVECTRON 3® LIGHTNING CONDUCTOR IS CALCULATED ACCORDING TO FRENCH STANDARD NF C 17-102 : 2011, THUS :
Rp (h) = √2rh -h² + Δ(2r + Δ) for h ≥ 5m et
Rp= h x Rp (5)/5 for 2m ≤ h ≤ 5m
The protection radius depends on a number of factors :
- h(m) : is the height of the ESEAT tip over the horizontal plane through the furthest point of the object/area to be
- r(m) : 20 m, 30m, 45m or 60m according to the Protection Level I, II, III or IV assessed for the site using the Risk Analysis calculation (NF C 17-102 : 2011 Annex A).
- Δ (m) : Δ = Δ T x 106. Field experience has proved that is equal to the efficiency obtained during the ESEAT evaluation

Substantiating its compliance and reliability requires multiple standard references, test campaigns and field tests, conducted by our R&D engineers in more than 20 countries, from artic to tropical areas.
Lightning is a natural phenomenon. Lightning air terminals are exposed to a very large range of events: extreme climatic conditions (temperatures, humidity…), high intensity electrical shocks up to several hundreds of thousands of Amperes, unpredictable lightning frequency…
Lightning Protection standards such as NF C 17 102, UNE 21 186 or NP4426 include detailed testing procedures that covers such extraordinary tough conditions. The PREVECTRON 3® Connect successfully passed these series of tests. Its integrated Lightning Counter was also tested according to the IEC 62 561 – 6 Edition 2 standard, confirming its full compliance to all relevant standards in the industry.
Lastly, the IoT connected system requires specific attention to work in severe electro-magnetic lightning conditions and meet the CE marking requirements. INDELEC develops dedicated testing processes, both in the LiRi Lab and in real lightning conditions, to confirm the PREVECTRON 3® Connect compatibility in such environment.
