IEC 61400-1 Ed. 4.1 en:2025

Full Description

IEC 61400-1:2025 CSV- Specifies essential design requirements to ensure the structural integrity
of wind turbines. Its purpose is to provide an appropriate level of protection against damage
from all hazards during the planned lifetime.
This document is concerned with all subsystems of wind turbines such as control and protection
functions, internal electrical systems, mechanical systems and support structures.
This document applies to wind turbines of all sizes. For small wind turbines, IEC 61400-2 can
be applied. IEC 61400-3-1 provides additional requirements to offshore wind turbine
installations.
This document is intended to be used together with the appropriate IEC and ISO standards
mentioned in Clause 2.
