Lightning density based on lightning location systems (LLS) - General principles

Scope

<!-- NEW! -->
IEC 62858:2019 is available as <a href="https://webstore.iec.ch/publication/65897">IEC 62858:2019 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

 

IEC 62858:2019 introduces and discusses all necessary measures to make reliable and homogeneous the values of ground flash density, NG and ground strike point density, NSG, obtained from lightning location systems (LLSs) in various countries. Only parameters that are relevant to risk assessment are considered. This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

- Two informative annexes are introduced dealing with the determination of lightning density for risk calculation (Annex A) and ground strike point calculation methods (Annex B).
