CAN/CSA-C61400-2:08 (R2013)

This National Standard of Canada is based on International Standard CEI/IEC 61400-2:2006. 1 Scope This part of IEC 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. This part of IEC 61400 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. While this part of IEC 61400 is similar to IEC 61400-1, it does simplify and make significant changes in order to be applicable to small turbines. This part of IEC 61400 applies 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. This part of IEC 61400 should be used together with the appropriate IEC and ISO standards (see Clause 2).
