UEENEEG102A - Solve problems in low voltage a.c. circuits
Overview
This unit covers ascertaining correct operation of single and three phase a.c. circuits and solving circuit problems as they apply to servicing, fault finding, installation and compliance work functions. It encompasses safe working practices, multiphase circuit arrangements, issues related to protection, power factor and MEN systems and solutions to circuit problems derived from calculated and measured parameters.
Assessment
For Melbourne campuses
Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.
Students will be expected to demonstrate the following required skills and knowledge:
- alternating current quantities;
- phasors diagrams;
- single element a.c. circuits;
- RC and RL series a.c. circuits;
- RLC series a.c. circuits;
- parallel a.c. circuits;
- power in an a.c. circuit;
- power factor improvement;
- harmonics and resonance effect in a.c. systems;
- three phase systems;
- three phase star-connections;
- three phase four wire systems;
- three phase delta-connections and Interconnected systems;
- energy and power requirements of a.c. systems, and;
- fault loop impedance.
Required reading
The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by the Polytechnic and/or via the Polytechnic e-learning system.
