standard byInternational Electrotechnical Commission , 02/01/2026
IEC 61400-40:2026 provides the EMC requirements and test methods that apply to the
individual wind turbine and all the sub systems which are part of the wind turbine.
The current document applies to measurements on individual wind turbines and not multiple
wind turbines.
This document defines the requirements and test methods for the verification of the wind turbine
performance against radiated emissions and the immunity of their components against
conducted and radiated phenomena.
This document is applicable to onshore and offshore wind turbines.
Safety considerations are not covered by this standard.
