Contact SupplierWe are providing our valued clients with the cutting-edge Thunder Guard Lightning Protection System. Conforming to the stringent French Standard NF C17-102, Thunder Guard Lightning Protection System ensures efficient performance and longer service life. Thunder Guard Lightning Protection System has a larger protection radius compared to a conventional Franklin rod. Thunder Guard Lightning Protection System produces an upward streamer quicker than conventional air terminals and attaches the downward leader of the lightning strike in mid air, before it strikes any other object in the vicinity and safely conducts the lighting current to the ground via the down-conductor and the earthing system. Just before the lightning strike, Thunder Guard Lightning Protection System senses the rapid change in the ambient electric field and produces high voltage pulses that ionize the air particles around the device, generating an upward streamer that intercepts the downward leader of the lightning strike. Specifications & Standards
The ESE Principle The Principle of operation for ESE terminals is to create an upward propagating streamer earlier than conventional air terminals or other objects on the earth. Thunderguard does this by collecting and storing ground charge during the initial phase of a thunderstorm development. Once a thunderstorm begins creating downward step leaders, the ambient electric field intensity in the area of the ESE terminal increases. When this electric field intensifies, it triggers the terminal to release the stored ground charge, forming an upward streamer microseconds earlier than other objects in the immediate area. This development of an upward streamer earlier in time and space ensures that the Thunderguard ESE Terminal will be target of the developing lightning strike. The selection of the Thunderguard model, placement, and mounting height above the protected area all factor into formulas calculating the dimensions of the protection area. The standard protection radius R of the Thunderguard is linked (according to NF C 17-102 standard) to /_ T, to the protection levels I, II, III or IV and to the height of the Thunderguard above the protected structure (H, defined by NF C 17-102 as a minimum of 2 m). The NF C 17-102 standard includes four levels of protection. The protection radii of different models of Thunderguard are given in the table. Our experts will suggest the most suitable model after conducting a site survey.
