KHU-ELT-0345
This unit involves the skills and knowledge required to diagnose and rectify faults in systems controlling starting, speed, torque, power output, efficient running and braking alternating current (a.c.) motor drive systems. It includes working safely; interpreting technical data; applying knowledge of a.c. motor operating parameters to logical fault-finding techniques; implementing fault rectification, safety and functional inspection; testing; and reporting work activities and outcomes. The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 volt (V) a.c. or 120 V direct current (d.c.). Competency development activities in this unit are subject to regulations directly related to licensing. Where a licence or permit to practice i
