Lightning strike counter: CDR-High Sensitivity

CDR HS lightning counter.

High sensitivity lightning strike counter.

The CDR-HS lightning discharge counter is a device designed to detect lightning strikes on external lightning protection systems, especially suitable for passive systems (conductor meshes) and for down conductors in contact with metal structures.

REQUEST MORE INFORMATION

Mesh systems or Faraday cages are characterized by current leakages that make it difficult to detect low- and medium-intensity lightning strikes with standard counters according to IEC 62.561-6, as these may be harmless or go unrecorded. For this reason, the high sensitivity of the CDR-HS detection system is the ideal solution for this type of installation. The installation of the CDR-HS counter is recommended in:

Faraday cages with various current return paths.
Down-conductors in contact with metal walls, in case that metal walls are grounding.
When the down-conductor has various anchor sets in a metal wall and the lightning counter is situated in the middle of them.
