Prevectron 2 Millenium S 4.50

Family : Lightning Conductors
Category : Prevectron®

Operation

The Prevectron® 2 is operating in three stages :

• The ionization device is charged via the lower electrodes using the ambient
  electrical field (several million volts/meter when storms are prevalent). This means
  the Prevectron® 2 is a fully autonomous system requiring no external power supply.
  

• The ionization phenomenon is controlled by a device which detects the
  appearance of a downward leader: the local electrical field increases rapidly when a discharge is imminent.
  The Prevectron® 2 detects changes within the field, making it the first E.S.E. air terminal to react at the precise moment
  the downward leader develops from the cloud to the ground.
  

• Early triggering of the upward leader using a system of spark ionization between the upper electrodes and the central
  tip. The Prevectron®2’s ability to trigger an upward leader ahead of any other protruding point within the protected
  area ensures it will be the preferential point of impact for the lightning discharge.
  

Key Benefits

The skills of INDELEC’s engineers, the variety of tests carried out in both high-voltage laboratories and real-life lightning conditions,
and the experience gained from the several dozens of thousands of PREVECTRON® 2 installations around the world, have allowed
us to develop a complete range of lightning conductors offering a host of key benefits :

• 8-model range offering customized solutions for each project (aesthetic constraints,
  required protection area, etc.);

• Fully autonomous operation;

• Total reliability, even in extreme climatic conditions;

• Proven, robust design able to withstand multiple lightning strikes;

• Lightning condutor only becomes active when electrical field intensity rises (lightning
  discharge likely), the PREVECTRON® 2 presents no danger to the site;

• Straightforward installation and maintenance using tools specially developed by
  INDELEC, including protection calculation software, strike counter and Prevectron® 2
  tester;

• High-voltage laboratory test results available on request;

• Ultra-safe capture tip thanks to full electrical continuity between the tip and the earth point;

• ISO 9001-2000 manufacturing process;


• Fully testable on site.

Protection area

The protection area Rp of a PREVECTRON®2 lightning conductor is calculated according to French standards NFC 17-102 compliant.
The protection area depends on a number of factors:

• Gain in triggering time ∆T of the chosen PREVECTRON®2 which allows the ∆L value to be determined according to the formula ∆L (m) = V(m/µs) .∆T(µs).

• The protection level required (I, II, III or IV) on a given site, according to the lightning risk assessment guide

• The actual height of the lightning air terminal above the surface to be protected (h)
