Description
Employability Skills
Learning Outcomes and Application This unit involves the skills and knowledge required to diagnose and repair faults in power generation plant inverter systems, including associated accessories, components and wiring systems.The diagnosis and repair of inverter system faults requires the inspection, repair and verification to ensure that it is working efficiently and meeting operational requirements.Competency in this unit requires the ability to plan work, verify fault, find fault, determine cause of fault, repair fault and complete all 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 practiceThe 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.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
