Bibliography

IEC 61400-24:2010(E) applies to lightning protection of wind turbine generators and wind power systems. Defines the lightning environment for wind turbines and application of the environment for risk assessment for the wind turbine. Defines requirements for protection of blades, other structural components and electrical and control systems against both direct and indirect effects of lightning. Recommends test methods to validate compliance. Provides guidance on the use of applicable lightning protection, industrial electrical and EMC standards including earthing. Provides guidance regarding personal safety. Makes normative references to generic standards for lightning protection, low-voltage systems and high-voltage systems for machinery and installations and EMC.
