Certain industrial and social activities are sensitive to the effects of lightning. For example, companies where hazardous activities are performed and / or work outside, telecommunications systems, power generation companies, transportation and many others. Activities such as sports, outdoor events, etc. require lightning hazard warning information.

Each year, due to the direct or indirect effects of lightning strikes, property damage occurs, affecting the continuity of service in the public and private sectors. Also, lightning causes injury or serious human deaths worldwide throughout the year.

To cover these needs, in the European Union there is the European standard EN 50536-1: 11 and the in rest of the world, the international standard IEC 62793. These standards define the hazard warning system and how to implement lightning alarm systems.

Storm detectors classification (EN 50536-1:2011)

  • Class I: Detects the storm throughout its life cycle (Phase 1 through 4).
  • Class II: Detects IC (cloud-to-cloud) and CG (cloud-to-ground) lightning (Phase 2 through 4).
  • Class III: Detects CG (cloud-to-ground) lightning (Phase 3 to 4).
  • Class IV: Detects CG (cloud-to-ground) lightning (Phase 3) and other electromagnetic sources with limited efficiency.


WAT Franklin Plus E.S.E Lighting conductors offers a wide range of solutions adapted to these rules. On the one front, the PREVISTORM STORM DETECTOR system sets an isolated system capable of detecting the formation of storm clouds from the early stages.

Furthermore, the system by detecting lightning and precise location in real time, enables the generation of alarms when the storm approaches dangerously (in areas where the network LINET is already operating).

As well as the implementation of new LINET networks for large companies or state institutions interested in having its own network of lightning detection.
