91.120.40 - Lightning protection

IEC 62793:2020(E) 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...view more

This document defines the requirements and testing for joints of metal sheets, with or without insulating coatings, used as natural components in roofs, facades or walls of buildings, suitable to conduct lightning current in LPS where the interconnection of these metal sheets does not ensure durable electrical connection.
NOTE   This document does not deal with the lightning interception capabilities of these components. The connection clamps for connecting the metallic sheet with the down conduc...view more

EN-IEC 62858 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 Standard  applies to lightning protection of wind turbine generators and wind power systems. Refer to Annex M guidelines for small wind turbines. This document defines the lightning environment for wind turbines and risk assessment for wind turbines in that environment. It defines requirements for protection of blades, other structural components and electrical and control systems against both direct and indirect effects of lightning. Test methods to validate compliance are included. Guidan...view more

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 an...view more

This part of IEC 62561 specifies the requirements and tests for devices intended to count the
number of lightning strikes based on the current flowing in a conductor. This conductor may
be part of a lightning protection system (LPS) or connected to an SPD installation or other
conductors, which are not intended to conduct a significant portion of lightning currents.
LSCs may also be suitable for use in hazardous atmospheres and there are therefore extra
requirements necessary for the compon...view more
