EARLY STREAMER EMISSION AIR TERMINAL TECHNICAL DATA SHEET EARLY STREAMER EMISSION AT WEIGHTED EARLY STREAMER EMISSION AT according to NFC 17-102 SECURITY COEFFICIENT GROSS WEIGHT The early streamer emission AT can be defined as the average gain in streamer emission time of the ESE air terminal (ESEAT) compared to a simple rod air terminal (SRAT) measured in the same conditions. AT is measured in a High Voltage Laboratory according to the NFC 17-102 Ed. 2011 Standard. The level of protection is given using the NFC 17-102 Edition 2011, EN 62305-2 or UTE 17-108 guide. If the site presents a risk for the environment, the protection radius must be reduced of 40%. For a level of protection I++ (cf.5.2.3.5 NFC 17-102), the protection radius must be also For a site subject to a lightning risk, it is necessary to carry out a lightning risk analysis (NFC 17-102, EN 62305-2 or UTE 17-108), then to define via a lightning technical study the specifica- The implementation of the necessary protections is done in accordance with the Standards of Initial or periodic verifications made it possible to supervise the evolution of the protection devices against lightning and to ensure the protection of the people and the goods. According to Art. 20 of the decree of 19.07.2011 of the French Minister of Ecology, the recording of the events must be done for the sites ICEP (Installations Classified for Environmental The lightning counter I0NIC0UNT® is the guarantee of the recording of essential information during the verifications on sites.

IONTFLASHfJJlICr TECHNICAL DATA SHEET EARLY STREAMER EMISSION AIRTERMINAL ■ WORKING STEPS OF THE IONIFLASH MACH® The Early Streamer Emission Air Terminal IONIFLASH MACH® protects against all lightning strikes positive or negative. The absence of fragile components reinforces its reliability and makes it not vulnerable to lightning impacts. It doesn't require any remote test for checking its functioning. An operational test procedure with two devices is available. The IONIFLASH MACH® is guaranteed 7 years (*). 1. Approach of the lightning phenomenon. 2. Detection of the lightning frequency by...
