Surge in Systems and Result
Surge in DC Application
An Arcing Fault is the flow of current through the air between phase conductors or phase conductors and neutral or ground. Concentrated radiant energy is released at the point of arcing an a small amount of time resulting in Extremely High Temperature.

PASSIVE PROTECTION SYSTEM
The ESE air terminal is a terminal which enables to generate artificially an upward leader earlier than a simple rod, with an ionization system, in order to establish a special impact on its point. The capture of the lightning strike being faster than a simple rod, this technology enables to benefit from larger protection areas, ensuring protection for large dimensions structures. The ge erated protectio radius depe ds o the early strea er e issio value of the air ter i al Δt i ¾s , its height, and the efficiency of the protection. The protection radius ensured by this type of air terminal is 120 m (Protection level IV, height = 60 m , early streamer emission time 60¾s) The NFC 17-102 standard describes the installation procedure for this type of air terminal. The installation of this type of air terminal is easy and cheaper than other technologies. It can protect whole buildings with one E.S.E. air terminal. It enables the protection of a structure and its environment, the protection of opened areas and well integrate in the architecture of a structure without aesthetic alteration.
1 ESE, 2 down conductors and 2 earthing systems are necessary to ensure the protection below :
