Protection systems

ACTIVE 4D® Early streamer emission

The innovation of the Active 4D® solution offers a complete system of lightning protection, permanently connected with the users. The lightning protection part uses the latest technology to advance the excitation upward leader. The Detection part uses the patented dual sensor (electrostatic) to inform the storm approaching.

As for the counter, it informs in real time all direct impacts on the Active 4D® and gives all features of the current. The LMS software allows to gather, in real time, all the information related to lightning phenomenon on site .With the connecting system if the user wishes to, it is possible to have access to the gathered data from anywhere in the world.

Principle and functionning

Lightning rod : the principle of the ESE Active 4D® is not only to initiate the upward leader, but to provide the energy needed to ensure its propagation until the junction with the downward leader. 

The Active 4D® system is equivalent to the ESE Active 2D® lightning conductor, featuring two devices: “Impulse” and “Power” devices.The Active 4D® operating system can be tested at anytime, either by a remote tester or by computer linked to the Activ’Control® housing (via local network), through the LMS software (Lightning Monitoring System).

The Active 4D® offers two models following to the excitation device speed: 30 and 60 µs. The system was tested in compliance with the September 2011 NF C 17-102 standard, in an independent laboratory accredited COFRAC.

Integrated impact counter : the Active 4D® allows to record lightning strikes autonomously. The innovation comes from a built-in lightning counter in the Active 4D® system. This lightning strike counter allows to timestamp and stores the various impact information captured by the Active 4D® (number of impacts, day / time of each impact, value, form and energy of the Lightning electric current).
This data is then transferred by radio link to the Activ’Control®. The operator, through the LMS software, has access to these various data and visualizes the curves of the lightning current. 

This device complies with the decree of 19th of July 2011 and with NF EN 62561-6 standard.

Integrated storm detector : The Active 4D® allows in predicting a storm. The detection works through 1 integrated sensor that measure with precision the electrostatic field value.
Once the recorded value indicate an imminent risk of lightning, the Active 4D® with its dry contact Activ’Control® housing, takes the initiative to send audio alerts (siren, …), and / or visual alerts (flashing light …).
The LMS (Lightning Monitoring System) software, permanently connected with the Activ’Control® (and thus the Active 4D®) allows visualizing the evolution of risk.
The great innovation of the system (patented) was to include prevention with lightning protection.
