Characteristics of the Active 2D® :
- Consideration of the energetic information to choose the tracer which can become an ascending tracer,
- Source of energy autonomous and clean : photovoltaïcs cells,
- Consideration of the cloud polarity,
- Optimized head curvature radius to reduce the corona effect and guarantee the excitation device,
- Operation guarantee in all atmospherical conditions,
- High resistance to corrosion thanks to its manufacture in 304 L stainless steel,
- In compliance with NF C 17-102 standard of September 2011
- Double device for a better propagation of the ascending tracer
- Remote test for an easy maintenance
- Test in High Voltage in the laboratory of Bazet in France (laboratory totally independant – laboratory patented COFRAC)
- Warranty of two years
When approaching storm activity, the integrated sensor measuring the surrounding electrical field, releases the impulse device such as most of usual Early Streamer Emission systems. It almost immediately reverses the polarity of their head, creating a sudden amplification of the electrical field on its tip.
The innovation comes from the use of a second device, named « power device », which collects and stores energy in power capacitors. The Active 2D® is in this way permanently pre-loaded of an important energy which allows maintaining the ascendant tracer propagation.
When the downward leader enters in the protection area of the lightning conductor, the measured current strongly increases. As soon as this current is superior to a characteristic threshold, the power capacitors discharge and release the necessary energy for the propagation of the leader. In this last device, the lightning conductor’s head is used as a capture device. It is, by consequence, electrically insulated from the earth.
