PROTECTION AREA 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. 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. PROTECTION RADIUS PROTECTION LEVEL I : r = 20M REAL LIGHTNING CONDITION TEST CAMPAIGNS The PREVECTRON 3® has fully benefited from unique experiences during its development process. Numerous engineering innovations have been totally validated in real lightning conditions. PROTECTION LEVEL III : r = 45 M Diameter (body) Diameter (Maxi) EARLY STREAMER EMISSION LIGHTNING CONDUCTOR FOR OPTIMUM LIGHTNING PROTECTION PERFORMANCE From the early stages of the PREVECTRON 3® development, INDELEC has integrated sustainable development requirements: 100% made in France, reduced weight, increased lifetime, modular design…. Thanks to its “In Planet” label, the new PREVECTRON 3® lightning conductor has been awarded the Prize of Excellence by the AvniR Adjudication Team, promoting the eco-design expertise and innovation within businesses. ADVANCED TRIGGERING

STANDARD COMPLIANCE Being an active member of major International, European and French standard committees, INDELEC is dedicated to develop fully compliant lightning protection solutions. The development, the manufacture, the test procedures and the installation of the PREVECTRON 3® comply with international and French standards, especially the NF C 17-102 : 2011 and UNE 21-186 : 2011 standards. MAXIMAL LIGHTNING PROTECTION In addition to the Prevectron® models advanced technical specifications (fully conductive central rod, dynamic calculation of the surrounding electrical field, autonomous...
