4、 Working principle

Under lightning conditions, when the downward leader of lightning approaches the ground, any conductive surface will produce an upward leader. In the case of passive lightning rods, only after a long period of charge recombination, will the upward leader propagate. The excitation time of the upstream pilot of the early discharge arrester is greatly shortened.

Under the high static electric field characteristics before lightning discharge, the early discharge arrester will generate controllable amplitude and frequency pulses at the needle tip, which will cause the lightning rod to generate an upward leader and propagate upwards, thereby intercepting the downward leader emitted from the thunderstorm cloud.

5、 Protection scope

The pre discharge lightning rod has a standard protection radius Rp *. According to the NFC17-102 1995 standard, the value of Δ T is as follows, with protection levels I-III (calculated according to Appendix B of NFC17-102). The height H (H, defined by NFC17-102, minimum 2 meters) of the pre discharge lightning rod on the protected building.

6、 Design support

The unique computer-aided design program provides the highest level of lightning protection for a range of design techniques and standards, including NFC17-102 and UNE-21186 standards. Based on specific site parameters such as building size, lightning rod model, and protection registration, each design is tailored to the specific project and provides elevation, 3D, and floor plans, as well as specially optimized designs for your facility.

7、 Installation and use:

1. Installation method:

After opening the packaging, place the lower part of the lightning rod in the reserved installation position, and use M18 × 60 stainless steel bolt fittings to install and tighten it. Welding connections can also be made as needed.

2. Installation precautions:

Ensure a reliable electrical connection between the lightning rod and the lower part;

The system is well grounded, and its grounding resistance should be less than 10 ohms;

The protected area should be calculated according to the rolling ball method specified in the "Code for Design of Lightning Protection of Buildings".
