Lightning counter

Electro-mechanical lightning discharge counter.

The lightning counter CDR-11 is a device designed to detect lightning strikes upon any external lightning protection system(lightning rods, ESE, faraday cages, etc…).

CDR-11 detects the electrical energy that is derived to the ground trough a conductor when a lightning impact occurs. The device registers each impact incrementing the counter in one unit each time. CDR-11 must be installed in the down conductor that connects the lightning rod to the grounding system. It does not use any type of power supply because it uses the electric energy of the lightning.

  • Great register capacity (999 impulses).
  • Easy visual control.
  • Detection of impulses from:
    • Intensity min: 1kA (8/20μs according to 62.561-6:2011).
    • Intensity max: 100kA (10/350μs according to 62.561-6:2011).
  • Compact and robust design.
  • Durability.
  • Easy adaptation to the down conductor of any lightning protection system.
  • Allows controlling the lightning rod condition.
  • Works in any atmospheric condition (from -20ºC to 65ºC).
  • Offers updated and reliable information.
  • It does not need power supply.
  • Easy installation and operation.
