Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.
Pre-requisites and Co-requisites
UEENEEG048A Solve problems in complex multiple path power circuits
This unit covers procedures for determining correct operation of complex polyphase power circuits and providing solutions as they apply to electrical power engineering work functions. It encompasses working safely, problem solving procedures, including using electrical measuring devices, applying appropriate circuit theorems and providing solutions derived from measurements and calculations and justification for such solutions.
National Codes, Titles, Elements and Performance Criteria
National Element Code & Title:
UEENEEG049B Solve problems in complex polyphase power circuits
1. Prepare to solve problems in complex polyphase power circuits
1.1 OHS procedures for a given work area are identified, obtained and understood.
2. Solve problems in complex polyphase power circuits
2.1 OHS risk control work measures and procedures are followed.
3. Complete work and document problem solving activities

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 .
