The NF C 17 102 Standard requires that the average values for time to break down and the standard deviation of those values be recorded calculated and compared. The standard
deviation for an ESE terminal must be a minimum of 20% lower than a simple air terminal in order to comply with the standard.
The patented OptiMax technology neutralizes space charge formation at the tip of the air terminal prior to triggering the upward streamer. The Prevectron 3 S60
utilizing OptiMax technology provides standard deviation that is 60% lower than a standard air terminal (40% lower than the NF C 17-102 requirements). This 60% reduction in the standard deviation provides a
more reliable streamer development under real lightning conditions for more reliable protection.
