THE PROTECTION AREA (RP) OF A PREVECTRON 3®
LIGHTNING CONDUCTOR IS CALCULATED ACCORDING
TO FRENCH STANDARD NF C 17-102 : 2011, THUS :
Since 1993 INDELEC has conducted unrivaled in-situ test campaigns,
allowing its engineers to assess the lightning conductors in real lightning
conditions.
Rp (h) = √(2rh-h2 + Δ (2r + Δ)) if h ≥ 5m
and
Rp= h x Rp(5)/5 if 2m ≤ h ≤ 5m
These test campaigns were originally developed in close cooperation with a team of engineers from
the Atomic Energy Commission (C.E.A.), Universities, Research Centers and private partners. These
test campaigns provide a wealth of experience in the field of lightning phenomena.
The protection area 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 protected.
• 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).
In order to gather as much data as possible, the tests were performed in America, Europe and Asia,
with each location providing very different lightning conditions. In 2015, INDELEC inaugurated the
new International Lightning Research Center of Jatiluhur – Indonesia.
Test campaigns have provided invaluable data to the Lightning Innovation and Research
Institute LiRi engineering team, including :
• Δ (m) : Δ = Δ T x 106. Field experience has proved that is equal to
the efficiency obtained during the ESEAT evaluation tests.
• Advanced performance of the PREVECTRON® through measuring and comparing electrical
activity at the tips of various lightning rods.
• Operation of the PREVECTRON® triggering system.
• Confirmation of the PREVECTRON® robust design by exposing it to repeated discharges.
• Total reliability provided by the PREVECTRON® in a wide range
of situations, encompassing all types of lightning conditions, including
upward & downward lightning strikes and tropical & winter storms.
• Release of a number of scientific reports in relation to this research.
