LASER IONIZATION : a next-generation protective system

High-intensity laser technology opened a new chance to develop a next-generation protective system that prevents lightning from striking a building. Beams of high-energy focused light can strip electrons from molecules in the air. This ionizes the molecules and leaves behind a plasma channel, which a lightning strike would see as a path of least resistance. This would attract the lightning and provide a route that it would follow down into the ground. A similar but different technology is based on ionizing a channel through the air, locally lowering the gas density through heating and thereby creating a guide for the discharge along which there is reduced breakdown voltage.

Thanks to its supreme know-how and technical infrastructure, L-Ion is involved in crucial reasearch and development projects. And working double time to have all of it’s ESEs to adopt “Laser Trigered Ionisation” by around 2022.

Laser trigered ionisation technology has certain advantages over the existing lightning protection devices. These advantages has been validated through the experimental envinronments. And L-Ion has a mission to bring this product alive from the experimental environment to our daily lives. Numerous universities worldwide are working on this technology some of these being University of Arizona and University of Central Florida.

A novel method has shown that lasers cannot only be used to guide discharges along straight lines, but also arcs and s-shapes. Instead, the light may be concentrated along a line, as within a Bessel beam (created using an axicon, or conical, lens), or along a parabola, as within an Airy beam (created using a binary phase mask). Both Airy and Bessel beams have the unusual ability of being able to “self-heal” – if their intensity peaks are blocked, these lasers may be able to reconstruct themselves on the other side of the obstacle. This is thanks to how different points along these lasers are sustained by different portions of the input beam that creates them.

A different approach is geo-engineering. Researchers are making progress in using ultrashort laser pulses to create lightning and cue cloud formation, with potential applications in agriculture, public safety and beyond. Today,it is possible to trigger electric discharges between charged electodes at distances reaching 500m. by sending a multi terawatt short laser pulse into the atmosphere.

ACTIVE LIGHTNING PROTECTION SYSTEM

HOW IT WORKS

OUR DESIGNS ARE TESTED

L-ion Active Terminals protect located areas with an Early Streamer Emission system has as a estimated target it to the lightning strike to protect the rest of the protection area. If a lightning rod has a mechanism generating ionization near top of the ESE terminal, then its lightning capture area is greatly increased. The operating principle is the same as a simple rod, but an additional ionization system getting cover a greater protection radius.

Our Knight and Hawk ESE models carry ground point to top of the structure, closer to downward leader point. This is also what a simple rod makes. In additional, Knight and Hawk generates controlled electrically charged area and pulses at the tip of the terminal during high static fields prior to a lightning discharge. This enables the creation of an upward leader from the terminal that spread to the downward leader coming from the cloud.

L-ion’s Knight and Hawk-Series tested at an independent and accredited laboratory in accordance with the revised 2011 requirements of French NFC 17-102 and UNE 21 186 standards.

After these tests; L-ion’s ESE models have proven that they carry lightning currents in a sturdy way and provide protection at a diameter in accordance with the standards. This can be checked by the relation of the NFC 17-102 giving the radius of protection of an ESE lightning conductor according to the level of protection.

HOW TO CALCULATE PROTECTION AREA?KNIGHT and HAWK can provide a protection area much greater then a simple rod. The protection level and the ∆T value are used together to calculate the protection area. Protection Level has been determined by the Standarts. The ∆T value of KNIGHT and HAWK has been determined by an independent lab test.

The ESE Lightning Rods KNIGHT and HAWK can protect a Radius (Rp)related to their ∆T value. It can be calculated according to following formula;

The protection radius of an ESEAT is related to its height (h) relative to the surface to be protected, to its efficiency and to the selected protection level (see Annex A).

To have Protection Radius; needed to know what is the protection level for the structure that you want to protect.

According to IEC and NFC Standarts; there are two main parameters. First one is the Protection Level which is determinated in the standarts. There are 4 Protection Levels such as;

There is a calculation method in the standarts consisting of basic questions such as; if the object is inhabited or not; if the object is explosive or not..etc.

The values obtained according to the answers of these questions are used together with Annual Average Thunder Days value to determine the protection level.

Rp

H

where

Rp (h) (m) is the protection radius at a given height h

h (m) is the height of the ESEAT tip over the horizontal plane through the furthest point of the object to be protected

r (m) 20 m for protection level I

30 m for protection level II

45 m for protection level III

60 m for protection level IV

(m) = T x 106

Field experience has proved that is equal to the efficiency obtained during the ESEAT evoluation tests

Protection Levels

LEVEL 1 Very High Risk Structures

LEVEL 2 High Risk Structures

LEVEL 3 Medium Risk Structures

LEVEL 4 Low Risk Structures

Rp (h) = √ 2rh - h2 + (2r + ) for h ≥ 5 mand

Rp = h x Rp (5) / 5 for 2 m ≤ h ≤ 5 m KNIGHT
