Wind energy generation systems - Part 40: Electromagnetic compatibility (EMC) - Requirements and test methods

Scope

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.
