Franklin France lightning conductor – Active 4D model

The ACTIVE 4D early streamer emission lightning conductor is a technologically advanced lightning protection device combining four functions in one unit:
– two emission devices , with autonomous and independent energy sources.
– The impulse device stores electrostatic energy from the atmospheric electric field as storm clouds approach and initiates an upward streamer at the appropriate moment.
– The power device collects and stores solar energy in several high-power capacitors.

This keeps the Active 4D precharged with a substantial amount of energy, enabling it to support upward streamer propagation for as long as necessary to capture lightning efficiently.

– integrated lightning strike counter with remote data transmission . When a strike occurs, the information is transferred to the software, providing the impact date and time and the lightning current value in amperes.

– integrated storm detector with remote data transmission . Active 4D has two sensors measuring electrostatic and electromagnetic fields. The alarm threshold is configured in the computer software, and the detection range can reach 30 km.

Testing and analysis

Active 4D operation can be tested remotely from a computer and using the remote control. The immediate remote test provides:
– Graph of solar-cell voltage
– Graph of battery voltage
– Graph and values of lightning conductor temperature in degrees Celsius
– VHV test and value

Active 4D lightning conductors have a 2-year warranty.
