CAN/CSA C61400-24:24 ✓ Most Recent

CSA Preface 

This is the second edition of CSA C61400-24, Wind energy generation systems — Part 24: Lightning protection , which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 61400-24 (second edition, 2019-07). It supersedes the previous edition, published in 2012 as CAN/CSA-IEC 61400-24 (adopted IEC 61400-24:2010), Wind turbines — Part 24: Lightning protection. For brevity, this Standard will be referred to as "CSA C61400-24" throughout. The Canadian deviations reflect requirements for areas of high resistivity. This Standard is intended to be used in conjunction with CSA C22.2 No. 272:20, Wind turbine electrical systems. This Standard was reviewed for Canadian adoption by the CSA Subcommittee on Wind Turbines — Lightning Protection, under the jurisdiction of the CSA Technical Committee on Wind Turbines and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 

Scope 

This part of IEC 61400 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. Guidance on the use of applicable lightning protection, industrial electrical and EMC standards including earthing is provided. Guidance regarding personal safety is provided. Guidelines for damage statistics and reporting are provided. Normative references are made to generic standards for lightning protection, low-voltage systems and high-voltage systems for machinery and installations and electromagnetic compatibility (EMC).
