Early Streamer Emission (ESE) Lightning Protection System – PrimeR© Model​

The PrimeR© Early Streamer Emission (ESE) lightning protection system, manufactured by Indelec and imported from France, is designed with cutting-edge technology to efficiently trigger an emission signal when surrounding electric fields increase—a clear indicator of imminent lightning activity.​

Based on scientific research on thunderstorms and lightning phenomena, PrimeR© offers a simple yet highly effective working principle. The device activates only when lightning occurs, ensuring precise and safe operation. It is built with a robust structure, capable of withstanding high-intensity weather and conducting up to 100 kA of lightning current.​

PrimeR© is also the first ESE lightning rod compliant with the NF C 17-102: 2011 standard and operates in a fully autonomous manner—requiring no batteries. It draws energy directly from the electric field generated during thunderstorms. The system is designed with continuous conductivity from the tip to the grounding connection and is installed in parallel with the main conductor, ensuring optimal performance and safety.​
