Scope:

Note: The scope and project need for this NOI (originally published on December 6, 2022) were updated by the responsible SDO on February 13, 2024.

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).  

Project need:

To maintain alignment with international requirements. This proposed New Edition is being developed at the request of the CSA Technical Committee on Wind Turbines. It will provide the industry with up to date requirements related to Wind Turbine Lightning Protection.
