IEC 61400
Purpose and functionHarmonizationWind Turbine Generator (WTG) classesList of IEC 61400 parts
IEC 61400 is a set of design requirements made to ensure that wind turbines are appropriately engineered against damage from hazards within the planned lifetime. The standard concerns most aspects of the turbine life from site conditions before construction, to turbine components being tested, assembled and operated. Wind turbines are capital intensive, and are usually purchased before they are being erected and commissioned
