Protection against lightning – Thunderstorm warning systems - Edition 1.0
 N 62793

Annotation

This International Standard 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 standard includes:

• a general description of available lightning and storm electrification hazard warning systems;

• a classification of thunderstorm detection devices and properties;

• guidelines for alarming methods;

• a procedure to determine the usefulness of thunderstorm information;

• some informative examples of possible preventive actions.

The following aspects are outside the scope of this standard:

a) lightning protection systems; such systems are covered by the IEC 62305 series;
