Satelit + Early Streamer Emission Lightning Rod

French DUYAL-MESSIEN Lightning Protection Equipment Company was formed by the merger of DUYAL, established in 1835, and MESSIEN, established in 1927. It is now a leading professional lightning protection company in the world, with its main product being the "Satelit +" brand early streamer emission lightning rod (pioneer lightning rod). Guided by scientific research, the company is one of the main manufacturers of early streamer emission lightning rods in France. It is a member of the French Electrotechnical Union (V.T.E. Commission) and one of the French representatives in the International Electrotechnical Commission (I.E.C), the authoritative body for setting new international standards.

All the company's products for direct lightning protection guarantee compliance with the current strictest French national lightning protection standard—NFC 17-102.

Its lightning protection products enjoy a high reputation in Europe and Southeast Asia. The French "Satelit" brand early streamer emission lightning rod (pioneer lightning rod) complies with the national lightning protection standard GB50057-94 "Code for Design of Lightning Protection of Buildings".

Satelit Lightning Rod

I. Working Principle of the Satelit Early Streamer Emission Lightning Rod (Pioneer Lightning Rod)

When a thundercloud forms, an electric field (atmospheric) is generated between the cloud and the ground, with a field strength that can reach 5 kV/m. This causes corona discharge to begin on protruding parts or metal components on the ground.

When a downward leader forms within the thundercloud, a lightning strike begins. The downward leader charge moves toward the ground in a step-like manner. The charge carried by the downward leader establishes an electric field on the ground.

An upward leader is generated from buildings or objects on the ground. This upward leader propagates upward until it meets the downward leader. At this point, the lightning current flows through the formed channel. Other buildings on the ground may generate several upward leaders. The first upward leader that meets the downward leader determines the location of the lightning strike.

The working principle of the "Satelit" brand early streamer emission lightning rod (pioneer lightning rod) is to generate an upward leader faster than that of a conventional lightning rod.

Note: This description only addresses negative downward lightning strikes, which are the only application case of the electro-geometric model. So far, this type of lightning strike is the most frequently occurring.
