Course Learning OutcomesAfter completion of this course, students will be able to:1) Describe power quality issues in a power system and indicate their key characteristics.2) Apply the concept of fault level to simple power systems to determine the short-circuit currents under faulted conditions, voltage dips during induction motor starting, and harmonic voltages associated with harmonic currents.3) Apply symmetrical component theory to analyse unbalanced steady-state operation of induction motors.4) Understand the importance of Australian Standards and perform comparisons with the power quality harmonic current and flicker limits given by the Standards.5) Describe the operating principles and construction of induction machines and the sensor types used for condition monitoring.6) Describe the process for obtaining frequency spectra of sensor signals and select appropriate values for the A/D input range/resolution and the sampling rate/time.7) Analyse the current, flux and vibration spectra to estimate the operating speed, slip, output torque and number of rotor bars.8) Analyse the current spectrum to identify the broken bar sidebands and estimate the number of broken bars.9) Analyse the sensor spectra to identify possible stator, rotor, bearing or eccentricity faults.10) Develop practical skills in using voltage, current and flux sensors, processing signals to obtain frequency spectra and analysing the results for power quality and condition monitoring testing.

Learning & Teaching Activities
Learning & Teaching ModesThis course relies on lectures and experimental tests as the primary delivery mechanism. Tutorials supplement the lectures to enhance understanding. Two assignments will be used to provide hands-on experience for students to reinforce the theoretical concepts encountered in lectures and to improve technical report writing abilities. In addition, continuous assessment activities provide formative opportunities for students to gauge their progress and understanding.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

Note that there will be two practical sessions to obtain real time data for Assignment 1 and Assignment 2. Further instructions on the operation of the tests and laboratory session will be provided. Occupational Health and Safety inductions will be conducted at these times.
Learning Activities SummaryNot applicable.
Specific Course RequirementsNot applicable.
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment activity Type Weighting Three in-class quizzes Summative 70% Two experiment reports Formative 25% Tutorial preparation Formative 5%
Assessment Related RequirementsA hurdle requirement is defined by the University's Assessment for Coursework Programs policy as "...an assessment task mandating a minimum level of performance as a condition of passing the course.
The experimental section is a hurdle requirement. It is necessary to achieve at least 40% total for these two reports. If this is not achieved, the total course mark will be limited to a maximum of 49.
If a student fails to meet a hurdle requirement (normally no less than 40%),and is assigned a total mark for the course in the range of 45-49, then the student is entitled to an offer of additional assessment of some type. The type of assessment is to be decided by the School Assessment Review Committee when determining final results. The student’s final total mark will be entered at no more than 49% and the offer of an additional assessment will be specified e.g. US01. Once the additional assessment has been completed, this mark will be included in the calculation of the total mark for the course and the better of the two results will apply. Note however that the maximum final result for a course in which a student has sat an additional assessment will be a “50 Pass”.
If a student is unable to meet a hurdle requirement related to an assessment piece (may be throughout semester or at semester’s end) due to medical or compassionate circumstances beyond their control, then the student is entitled to an offer of replacement assessment of some type. An interim result of RP will be entered for the student, and the student will be notified of the offer of a replacement assessment. Once the replacement assessment has been completed, the result of that assessment will be included in the calculation of the total mark for the course.
Assessment DetailDetails of individual assessment tasks will be provided during the semester.
SubmissionAll written submissions to formative assessment activities are to be submitted to the designated boxes within the School of Electrical & Electronic Engineering by 3:00pm on the specified date and must be accompanied by a signed cover sheet. Copies of blank cover sheets are available from the School office in Ingkarni Wardli 3.26.
A 20% late penalty per day (or part of) will apply if the above reports are not submitted on time.
All formative and summative assessments will have a two week turn-around time for provision of feedback to students.
Full details can be found at the School policies website:
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
