UniEarth Protecting Man and Machine

Lightning Impulse Counter

  • This counter records each lightning stroke on a lightning protection system. This information can be useful to do the maintenance of impact.
  • Thanks to its reliable construction, this counter resists very well the outdoor difficult conditions (rain, sun). It is totally autonomous and requires no supply.
  • Its performance was tested in COFRAC laboratory, and is guaranteed until 100kA, on negative and positive lightning strokes.
  • Its small size allows it to be integrated discreetly on the lightning conductor.

Operation Placed directly on the lightning conductor, this meter uses fields shone by the current of lightning to activate an electromechanic meter.

Connection This counter is installed just in contact of the lightning conductor (round Ø 8 to 10mm, flat 30x2 or 30x3mm) above the inspection joint, and at 2 meters behind the ground (NF C 17-102).

Fastening The fastening is made on the counter with the stamped stainless steel plate Thanks to its light weight, the product can simply be supported be the lightning conductor.
