DIRECT STRIKE PROTECTION
Lightning Rods - Lightning Protection - Prevectron ESELC System
Being the leader in the field of effective lightning rods and lightning protection, Indelec has spent over 30 years developing and testing a terminal with superior lightning capture capabilities. The Prevectron terminal is no ordinary lightning rod and collects the increasing ambient energy of the potential difference between the ground and the cloud base of the storm. When this potential reaches a predetermined threshold, the cloud dispatches a downward leader. Upon detection of the propagation of this natural downward leader, the terminal releases the stored energy producing charged ions at its tip. These ions are then dispatched and produce the upward leader. Once this occurs, nature takes over and the natural attractions between the upward and downward leaders occur. The propagation of the upward leader is tens of microseconds ahead of naturally occurring leaders. LDU has installed hundreds of lightning protection systems in Australia and to date has not had a single recorded or witnessed failure of the terminal to intercept the downward leader to lightning strike.
Prevectron Lightning Terminals
A lightning protection system utilising the Prevection terminal complies with 9 international & national standards and is widely used in Australia and the South Pacific region. LDU can design, supply, install and certify a Prevection system for your building or structure. The system can be supplied in a DIY kit form with installation instructions, for the contractor who wishes to install the system themselves. However if this is the preferred installation method then LDU will certify the system to ensure the installation is of the highest quality. The range of Prevectron protection radii is from 65 meter to 107 meter, Level IV. Most models are also available with a self-testing system. These models are identified with a T attached to the end of the number.

PRIMER ESE LIGHTNING PROTECTION TERMINAL
Indelec are proud to announce the release of the new Primer ESE Lightning Protection Terminal manufactured by Protec Foundre of France. The Primer utilises our new tip variation technology which triggers an upward leader more efficiently as soon as the ambient electric field increases which is a sign of an impending lightning strike. The Primer working principle is the electronically controlled variation of the tip shape allowing the rod to optimise the efficiency by ensuring synchronisation with the natural phenomenon of lightning.

PREVECTRON TERMINALS
Protection Areas
French Standard NFC 17-102 requires that every ESE Lightning Conductor first undergo a series of high-voltage laboratory tests to determine the gain in triggering time in comparison to a simple rod. The value obtained - referred to as Δt - equals the average trigger time over a run of 100 electrical discharges in the laboratory, minus a 35% safety margin. This figure is then used to calculate each conductor’s protection area according to the standardized formula. From the outset, INDELEC subjected the PREVECTRON®2 to independent testing in laboratories across France (EDF facility at Renardières & Cediver Laboratory at Bazet) and internationally (Louvain University in Belgium, IREQ in Canada & KERI in South Korea). The tests highlighted the advantages of the PREVECTRON®2’s early triggering system compared to a passive rod and allowed each model’s average Δt value to be measured. The results of the tests have all been approved by the CNRS and are available on request.
Installation
Installation procedure for the PREVECTRON®2 is governed by French standard NFC 17-102 and follows a series of simple rules catering for all types of structure:
• The tip should be positioned at least 2m above the structure to be protected;
• With heights less than 28m, a single down conductor is sufficient (as long as the conductor’s horizontal projection is less than its vertical projection);
• The resistance of the grounding system should be less than 10Ω;
• PREVECTRON®2 activity can be recorded by installing a lightning strike counter;
• The PREVECTRON®2 has been designed for the most extreme climatic conditions (see the results of our real-life lightning tests). INDELEC also markets a tester allowing clients to regularly check the air terminal on-site.
Protection Area
The protection area Rp of a PREVECTRON®2 lightning conductor is calculated according to French Standard NF C 17-102, thus: Rp = √h (2D-h) + ΔL (2D + ΔL)
The protection area depends on a number of factors:
• Gain in triggering time ΔT of the chosen PREVECTRON®2 (see Technical Guide: high-voltage laboratory PREVECTRON® test results), which allows the ΔL value to be determined according to the formula ΔL (m) = V(m/μs) .ΔT(μs);
• D = 20, 30, 45, or 60, depending on the protection level required (I, II, III or IV) on a given site, according to the lightning risk assessment guide (C 17-108);
• the actual height of the lightning air terminal above the surface to be protected: h (where h < 5m, see table below).

REAL LIGHTNING CONDITION TEST CAMPAIGNS
The decision by Prevectron to go ahead with real lightning tests was based on a simple premise: laboratory testing cannot reproduce the complete parameters and constraints of a real lightning discharge. In addition to the extensive tests carried out in the laboratory in pursuance of French Standard NFC 17-102, INDELEC is one of the only lightning rod manufacturers to actively pursue real-life testing. The test campaigns were originally developed in close cooperation with a team of engineers from the Atomic Energy Commission (C.E.A.) in Grenoble. As work progressed, other companies, universities and scientists joined in the test campaigns, providing a wealth of experience in the field of lightning phenomena. In order to gather as many data as possible, the tests were performed in America, Europe and Asia, with each site offering very different lightning conditions. The first tests were carried out in 1993 at Camp Blanding in Florida, since when experimentation has moved on to Cachoeira Paulista in Brazil and Nadachi in Japan.

Each test campaign has provided invaluable results, including:
• Highlighting the performance of the PREVECTRON®2 through measuring and comparing electrical activity at the tips of various lightning rods;
• Operation of the PREVECTRON®2’s triggering system;
• Confirmation of the PREVECTRON®2’s robust design by exposing it to repeated strikes;
• Total reliability provided by the PREVECTRON®2 in a wide range of situations representative of all types of lightning conditions, including upward & downward lightning strikes and tropical & winter storms.
A number of scientific reports have been produced in relation to this research, which has also allowed the PREVECTRON® to be continuously developed from the initial design through to the latest Millennium model.

PREVECTION SELF-TEST
The self-testing Prevectron® Millennium lightning conductors (T series v2) allow to check that the triggering device is operating properly without having to access to the lightning air terminal. It consists of a test circuit integrated into the lightning conductor as well as an external solar powered energy and communication module fastened to the base of the central rod. The test is initiated from the ground or from the roof terrace, at a maximum distance of 50 m, using a dedicated radio remote control unit. The Prevectron® T v2 lightning air terminals indicate their operational status themselves by lighting up powerful red LEDs located under the stainless steel casing.
Characteristics
• The test procedure is triggered remotely.
• After a self-check cycle, the result of the test appears spontaneously.
• The analysis result is displayed directly on the lightning conductor.

PRIMER THE LIGHTNING ROD DATA SHEET
Tip Shape & Lightning Rod Capabilities Correlation
Recent lightning research has established that lightning rod performances, when submitted to an intense electrical field – as per thunderstorm conditions - are deviating to a large extent, depending on their tip shapes:
• A rounded tip delays the corona effect outbreak.
• A sharp pointed tip triggers an upward leader more efficiently as soon as the ambient electric field increases, sign of a risk of lightning strike.
The Perfect Shape at the Right Time
An artificially rounded tip will initially prevent the emergence of immature corona pulses. This maintains a clean environment favouring the lightning discharge process. In a second step, the highly-amplified sharp tip triggers corona pulses in line with the electric field evolution i.e. Once the E Field development can support the propagation of the upward leader. This “blunt to sharp” tip shape construction provides the perfect shape to trigger a timely upward leader. The Primer daringly innovative design is based on this concept.
New Unique & Patented Technology: The Tip Configuration Electronic Variation
The Primer working principle is the electronically controlled variation of the tip shape: an auxiliary high voltage is applied on a ring surrounding the tip, distorting the electric field lines. The behaviour of the rod goes from a rounded tip-alike geometry to a sharp one. The lightning rod optimum efficiency is ensured by the synchronisation of its operation with the natural phenomenon. The auxiliary circuit is fully autonomous and powered by the increasing atmospheric electric field. It comes into action short before the lighting discharge. This design consolidates the benefits of both tip shapes: the Corona effect development is constantly controlled with a round tip geometry that switches to a sharp-type, ensuring ideal conditions for the upward leader emission development, under mature atmospheric electric field conditions.
