UEENEEG006A - Solve problems in single and three phase low voltage machines
Overview
This unit covers ascertaining correct operation of single and three phase machines and solving machine problems as they apply to servicing, fault finding, installation and compliance work functions. It encompasses safe working practices, machine connections circuit arrangements, issues related to machine operation, characteristics and protection and solutions to machine 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:
- transformer construction;
- transformer operation;
- transformer losses, efficiency and cooling;
- transformer voltage regulation and percent impedance;
- parallel operation of transformers and transformer auxiliary equipment;
- auto-transformers and instrument transformers;
- operating principles of three phase induction motors;
- three phase induction motor construction;
- three phase induction motor characteristics;
- single phase motors - split phase;
- single phase motors - capacitor and shaded pole types;
- single phase motors - universal;
- motor protection;
- three phase synchronous machines- operation principles and construction, and;
- alternators and generators.
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.
