Active 1D Early Streamer Emission Lightning Rod

The Active 1D® excitation advance is obtained by a device  named « impulse device ». Its principle consists in storing   electrostatic energy present in the atmosphere at a stormy cloud approach to release the ascending discharge excitation in a good time. This device operates with an integrated sensor which measures the surrounding electrical field value. It generates then a polarity inversion of the lightning rod head, creating a sudden amplification of the electrical field on its point.
