Learning Outcomes
Details of Learning Activities
Classroom tutorial activities to consolidate the theory of concepts of three phase power circuit analysis. Activities involve theoretical and practical exercises of polyphase power circuit analysis, complex power single and three phase circuits, balanced and unbalanced loads, three phase loads, line voltage drops, neutral currents, fault currents, fault loop impedance and transformer percentage impedance.
Practical activities to develop skill in software applications for calculation fault levels and voltage drops and verification of results with circuit simulation softwares: PSPICE or Multisim.
Projects on analysis of induction motor and transformer equivalent circuits and calculations of voltage drops, fault currents and application of Australian Standards for determination of Fault Loop Impedance
may be undertaken as part of a team or individual basis.
Research activities is designed to be independent study to do project research, design, construction, testing and problem solving activities.
The skills and knowledge described in this unit require a licence to practise in the workplace where plant and equipment operate at voltage above 50 V .
