This unit involves the skills and knowledge required to diagnose and repair mechanical system faults in large scale wind turbine generators.

Diagnosing and repairing faults is the process of inspecting large scale wind turbine generators to identify problems and ensure repairs take place. The aim is to ensure that the overall delivery of the large scale wind turbine generators meets operational requirements.

Competency in this unit requires the ability gather data, interpret data to establish theory about wind turbine generator mechanical system faults, repair wind turbine generator mechanical system faults and record wind turbine generator mechanical system faults. Individuals will, in general, work under supervision in an electrical, electronic and/or mechanical equipment repair workshop or on site.

Power generation maintenance personnel are typically trained and authorised to receive permits to work.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Note: Workplace practice

The application of the skills and knowledge described in this unit of competency may require a licence or training permit to practice in the workplace, where work is carried out on gas and electrical installations. Additional and/or other conditions may apply under state and territory legislative and regulatory licensing requirements.
