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.
