  • Learning & Teaching Activities
    Learning & Teaching Modes
    The Power Quality and Condition Monitoring (Fault Diagnostics) course has two components:
    a. Power quality (PQ)
    b. Condition monitoring (CM)

    It uses the following learning and teaching activities:

    1. Lectures:
    a) PQ: these are pre-recorded and students will need to watch on between 2 and 6 hrs of lectures per week.
    b) CM: there will be up to 4 hrs of in-person lectures per week, these will be recorded for students who not able to attend

    2. Online tests (PQ only): these are MyUni tests which are done weekly and require an average of about 2 hrs per week.

    3. Workshops: there are six 2-hr workshops during the semester with preparation submitted before each one.  The preparation is expected to take on average about 2 hrs per workshop for the four PQ ones, but the two CM ones may require up to four hrs per workshop.

    4. Quizzes: there are two 90 minute open-book quizzes, one for PQ in Week 6 and one for CM in Week 11.  At least 12 hrs of preparation is recommended for each quiz.

    5. Experiments: there are three 3-hr experiments during the semester.  A time allowance of 1.5 hrs of preparation and 12 hrs for writing each of the reports is recommended.
    Workload

    The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

    This course has the standard University expectation of about 156 hours over the semester.  Please see the above Learning and Teaching Modes for more information on how this is broken down to the various course activities.

  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

    This course has two hurdle requirements. Meeting the specified hurdle criteria is a requirement for passing the course.
    Assessment Related Requirements
    A 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 component is a hurdle requirement. It is necessary to achieve at least 40% for the weighted total of the three reports. If this is not achieved, the total course mark will be limited to a maximum of 49.

    The quiz component is also a hurdle requirement. It is necessary to achieve at least 40% for the weighted total of the two quizzes. If this is not achieved, the total course mark will also 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

    No information currently available.

    Submission
    A 20% late penalty per day (or part of) will apply if experiment reports are not submitted on time.

    All formative assessments will be targeted to have a two-week turn-around time for provision of feedback to students.

  • Student Feedback

    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.

  • Student Support
  • Policies & Guidelines
  • 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’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.
