Course Learning Outcomes

On successful completion of this course students will be able to:

1	Describe and classify power quality issues in a power system; explain the importance of power quality;
2	Apply the concept of fault level to simple power systems to analyse fault conditions, voltage dips and harmonic voltages;
3	Apply symmetrical component theory to analyse unbalanced steady-state operation of induction motors;
4	Recognise the importance of 最新糖心Vlogn 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; and
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. Presenting results in a written report.

Learning & Teaching Modes

This 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.

Specific Course Requirements

Not applicable.

The 最新糖心Vlog'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 Summary

Due to the current COVID-19 situation modified arrangements have been made to assessments to facilitate remote learning and teaching. Assessment details provided here reflect recent updates.

Assessment Task	Weighting (%)	Individual/ Group	Formative/ Summative	Due (week)*	Hurdle criteria	Learning outcomes

This assessment breakdown is registered as an exemption to the 最新糖心Vlog's . The exemption is related to the Procedures clause(s): 1. b. 3.

This course has a hurdle requirement. Meeting the specified hurdle criteria is a requirement for passing the course.

Due to the current COVID-19 situation modified arrangements have been made to assessments to facilitate remote learning and teaching. Assessment details provided here reflect recent updates.

To support the changes to teaching, the following revisions to assessment have been made:-

1. Quizzes (PQ 22%, CM 20%, hurdle of 40% on total quiz mark):
These will be conducted physically with an online option for remote students only.

2. Experiments (PQ 15%, CM 25%, hurdle of 40% on total quiz mark):
These will be conducted physically with an online option for remote students only.

3. Tutorials (PQ 8%, CM 5%), tutorial preparation will be marked. Tutorials will be conducted physically and will be recorded for remote students and local students who are not able to attend.
Marking scheme
1 = completed at least 1/3 of questions
2 = completed at least 2/3 of questions
3 = completed all of questionsNote that it is necessary to show detailed working to receive marks -

4. On-line tests (PQ 5%): weekly tests as part of PQ component only

Assessment Related Requirements

A hurdle requirement is defined by the 最新糖心Vlog's 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 Detail

Details of individual assessment tasks will be provided during the semester.

Submission

A 20% late penalty per day (or part of) will apply if experiment 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.

Student Feedback

The 最新糖心Vlog 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 最新糖心Vlog 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.

Fraud Awareness

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鈥檚 disciplinary procedures.

The 最新糖心Vlog of Adelaide is committed to regular reviews of the courses and programs it offers to students. The 最新糖心Vlog of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
