This part of BS EN 61400 deals with safety philosophy, quality assurance, and engineering integrity and specifies requirements for the safety of small wind turbines (SWTs) including design, installation, maintenance and operation under specified external conditions. Its purpose is to provide the appropriate level of protection against damage from hazards from these systems during their planned lifetime.
BS EN 61400-2 is concerned with all subsystems of SWT such as protection mechanisms, internal electrical systems, mechanical systems, support structures, foundations and the electrical interconnection with the load.
This part of BS EN 61400 is similar to IEC 61400-1, but it does simplify and make significant changes in order to be applicable to small turbines. It is applicable to wind turbines with a rotor swept area smaller than 200 m2, generating at a voltage below 1 000 V a.c. or 1 500 V d.c.
BS EN 61400-2:2006 replaces BS EN 61400-2:1996, which has been withdrawn.
