Diagnose and repair faults in wind turbine control systems


Application

This unit involves the skills and knowledge required to diagnose and repair faults in wind turbine control systems, associated accessories and wiring systems.

The diagnosis and repair of faults in wind turbine control systems, associated accessories and wiring systems requires the inspection, repair and verification that they are operating efficiently and meeting operational requirements.

Competency in this unit requires the ability to plan work, verify fault, find fault, determine cause of fault, rectify or repair fault and complete work tasks. 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.
