Wind energy generation systems – Part 24: Lightning protection
|1 July 2019
|ICS Code (Wind turbine energy systems):
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).
