Studying online

There are now 3 possible online modes for units:

Units with modes Online timetabled and Online flexible are available for any student to self-enrol and study online.

Units available in Online Restricted mode have been adapted for online study only for those students who require the unit to complete their studies and who are unable to attend campus due to COVID border closures. To be enrolled in a unit in Online Restricted mode, students should contact their Student Advising Office through askUWA and include which of the below criteria applies:

  • You are a student who is currently offshore and unable to enter Australia.
  • You are a student in Australia who is impacted by state or regional border closures.

Content
This unit covers the theory of three-phase circuits, transformer models, DC and AC machines (synchronous and induction), equivalent circuits and performance relations (torque-speed relation, speed and voltage regulation, efficiency calculation).
Outcomes
Students are able to (1) demonstrate an ability to work effectively in laboratory teams; (2) analyse and compare two basic principles (generation of EMF and torque) that govern the electromagnetic energy conversion; (3) develop equivalent circuits for DC machines, transformers, induction and synchronous machines; (4) develop phasor diagrams for transformers, induction and synchronous machines; (5) using equivalent circuits, analyse and assess the performance (regulation, losses and efficiency) of DC machines, transformers, induction and synchronous machines; (6) differentiate between motor and generator operations for DC, induction and synchronous machines; (7) analyse torque-speed characteristics to develop speed control techniques for DC and induction motors; (8) develop transmission line parameters and power system representation; and (9) explain the working of special purpose electrical machines including single phase induction motors.
Assessment
Indicative assessments in this unit are as follows: (1) laboratory assignments and reports; (2) class tests; and (3) a final examination. Further information is available in the unit outline.

Supplementary assessment is not available in this unit except in the case of a bachelor's pass degree student who has obtained a mark of 45 to 49 overall and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
