Lightning counting Lightning Counting Lightning Measurement and Protection Lightning strikes form a major cause of faults in electrical apparatus. Lightning strikes can also lead to fires and other damage, resulting in death of people and livestock. In order to evaluate the risk of lightning strikes, and develop technically and economically correct methods of protection, it is important to know the quantity and magnitude of lightning strikes which occur in a given geographical area.
Geographical differences make it desirable to make lightning counts in localized areas.
Those interested are meteorologists, electricity supply companies, the military, and fire-insurance companies. The results revealed a need to determine the effective registration zone, and an evaluation of the proportion of lightning strikes to the earth, compared to those between clouds. The project is gradually increased by forcing the effective registration zone to cover a greater area of North Jutland, by installing counters in Vendsyssel and Himmer-land. This makes it possible to discriminate between lightning strikes, with a few seconds between them. As the Danish Meteorological Institute and Association of Danish Electric Utilities have installed a country-wide lightning registration system, it is possible to collect data enabling comparisons to be made between registrations made using both systems.
