Thunderstorm warning systems - Protection against lightning
IEC 62793:2020 describes the characteristics of thunderstorm warning systems (TWSs) in order to implement lightning hazard preventive measures.Single sensors and/or a network of sensors (e.g. lightning location system) can be used as a TWS.This second edition cancels and replaces the first edition, published in 2016. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:- portable devices are no longer covered by this standard;- in Clause 5, classes of TWS have been deleted;- in Clause 6, updated figures and more detailed text are provided to better illustrate the alarm timeline;- in Clause 9, the text has been summarized and refers now to the application guide given in Annex F;- annexes have been reorganized;- Annex E is normative.

Protection against lightning - Thunderstorm warning systems
IEC 62793:2016 describes the characteristics of thunderstorm warning systems and evaluation of the usefulness of lightning real time data and/or storm electrification data in order to implement lightning hazard preventive measures. This standard provides the basic requirements for sensors and networks collecting accurate data of the relevant parameters, giving real-time information of lightning tracks and range. It describes the application of the data collected by these sensors and networks in the form of warnings and historical data. This standard applies to the use of information from thunderstorm warning systems (systems or equipment providing real-time information) on atmospheric electric activity in order to monitor preventive measures. This bilingual version (2018-11) corresponds to the monolingual English version, published in 2016-05. The French version of this standard has not been voted upon.
