Early Streamer Emission

ESE Lightning Rod Prevectron 3

The Prevectron3 Early Streamer Emission air terminal introduces for the first time ever the OptiMax technology, neutralizing the space charges above the the tip of the rod. It enhances the lightning rod performances, both in High Voltage Lab and on site, resulting into an improved protection reliability.

Innovation lightning rod

OptiMax® Technology : Maximal lightning protection

In addition to the Prevectron® models advanced technical specifications (fully conductive central rod, dynamic calculation of the surrounding electrical field, autonomous system…) the PREVECTRON 3® includes for the first time the patented OptiMax® technology.The OptiMax® system has been developed by the Indelec engineers. It neutralizes the space charges surrounding the ESE conductor, prior to the triggering of the upward streamer. The latter can then progress in a perfectly controlled electrical environment.

This innovative system leads to a 40% reduction of the standard deviations measured in the High Voltage Laboratory. Less variations in the H.V. Laboratory mean a more reliable upward streamer development process under real lightning conditions. It therefore improves significantly the lightning protection performance and reliability.

First ever modular lightning rod

The PREVECTRON 3® also represents a major step in terms of maintenance of the lightning protection system. Each circuit is built and assembled separately. This unique modular design allows the possible replacement of a damaged module.

The condition of the PREVECTRON 3® can be periodically tested with the INDELEC Tester. It enables the client to check the lightning conductor’s operational capabilities during the full period of installation of the lightning protection system. This operation is conducted on site and does not require the lightning rod to be dismantled.

The INDELEC Tester meets the requirements of NF C 17-102 : 2011 for lightning protection system maintenance.

With a five (5) year warranty, thanks to its unique design, the PREVECTRON 3® provides its users with an extra-long lifetime.

Tests, Standards & Certifications

Standard compliance

Being an active member of major International, European and French standard committees, INDELEC is dedicated to develop fully compliant lightning protection solutions. The development, the manufacture, the test procedures and the installation of the PREVECTRON 3® comply with international and French standards, especially the NF C 17-102 : 2011 and UNE 21-186 : 2011 standards.

Uniquely manufactured in France, the PREVECTRON 3® has successfully been subjected to the full sequence of tests detailed in the NF C 17-102 : 2011 Annex C Standard :

  • Marking tests
  • Mechanical tests
  • Environmental tests in salt mist and humid sulfuric atmosphere
  • Electrical test (Voltage withstanding test @ 100kA – 10/350μs waveform)
  • Advanced triggering measurement in High-Voltage laboratory to determine the gain in triggering time in comparison to a simple rod

Test results are witnessed and certified by an internationally renowned independent inspection company : Bureau Veritas.

The world’s most accredited ESE lightning conductor

The PREVECTRON 3® development was conducted far beyond the standard requirements. The new ESE rod benefits from the following certifications :

  • UL Certified is affixed for the first time ever on an Early Streamer Emission lightning conductor. Underwriters Laboratories Inc (UL) is a global independent safety science company, one of the most renowned certification and testing group in the world.
  • Lightning current tests in Campinas, Brazil in UNICAMP laboratory : the PREVECTRON 3®has been submitted to over 200kA current discharges, whereas the standard requires 100kA discharges. The test results confirm the lightning rod’s perfect sustainability in extreme conditions.
  • Qualifoudre certificate N°051166662001 confirms INDELEC’s quality management system, manufacturing methods and staff capabilities are compliant with the QUALIFOUDRE standard.
  • CE marking is also affixed on the PREVECTRON 3® for the first time. INDELEC’s new lightning rod meets with all relevant European Directive requirements
