ESE lightning conductor type Active 2D®,

The effectiveness of a lightning conductor does not depend only on the excitation time of a leader to the rod.

The operating principle of the Saint Elme Active 2D® consists, not only to initiate the upward leader, but moreover, provides enough energy to ensure its propagation until the junction with the downward leader:

  • A first device, named « impulse device» stores the electrostatic energy present in the atmosphere at the approach of a stormy cloud and releases the excitation of the ascending discharge at the right time.
  • A second device, named « power device », collects and stores the wind and / or the solar energy in several strong power capacitors. The Saint Elme® lightning conductor is in this way permanently pre-loaded of an important energy which enables him to support the propagation of the ascendant tracer.

Characteristics of Saint Elme Active 2D® lightning conductor:

  • Take in account the energetic information to choose the tracer which can become an ascending tracer.
  • Maintain the propagation of the tracer by discharge of the power device.
  • Source of energy autonomous and clean:

– Solar (2) or wind (1) energy for the power device

– Atmospheric electrical field for the impulse device.

  • Consider the cloud polarity.
  • Radius of curve of the head optimize to reduce the corona effect and guarantee the excitation device.
  • Protection of the electrical part against the rain with a dimensioned flange.
  • High quality materials, esthetical.
  • Use of stainless steel to resist against corrosion.

The Saint Elme Active 2D® lightning conductor was tested in the high voltage laboratory Bazet (CEB) in compliance with the NF C 17-102 standard, and is subject of tests campaign in situ.

The Saint Elme Active 2D® lightning conductor can be tested on site with his remote control tester.

Simple and fast, the test does not require any particular operation of lightning conductor dismounting and can be done safety from the ground.

Active 2D® remote control testers use the communication by Radio waves, and create any electromagnetic perturbation.

Saint Elme Active 2D® lightning conductors and their testers are both equipped with one transmitter / receiver:  bi-directional emission and reception.
