# ELE1801 Electrical Technology

 Semester 2, 2012 External Toowoomba Units : 1 Faculty or Section : Faculty of Engineering & Surveying School or Department : Electrical, Electronic & Computing Version produced : 30 December 2013

## Staffing

Examiner: Ron Sharma
Moderator: Leslie Bowtell

## Requisites

Pre-requisite: ENG1500 or MAT1500 or Students must be enrolled in the following Program: MEPR

## Synopsis

Electrical engineering is about the use of electrical and electronic technology to achieve most of our daily needs. To understand how electricity is used to achieve these needs, in Electrical Technology, students are provided with a working knowledge of electrical components, machines, power supply systems and safety devices commonly encountered in the workplace. Analysis of DC and AC circuits, transformers, motors, generators, power supply systems, batteries and rectifiers form part of the work.

## Objectives

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

1. explain the physical basis of common electrical devices and apply the basic laws and conventions governing them to solve simple energy conversion problems;
2. select common electrical components, devices and signal sources for use in simple DC and AC circuits;
3. analyse simple DC circuits using Kirchhoff's Laws and network theorems;
4. calculate m.m.f, flux density, reluctance, force torque, induced e.m.f. related to magnetic circuits;
5. determine the no-load and on-load characteristics of DC motors and generators;
6. analyse simple single phase and three phase AC circuits;
7. construct phasor diagrams and use phasors to analyse single phase and three phase circuits;
8. predetermine the performance of transformers using given equivalent circuit data;
9. explain and compare the principles of operation and the applications of AC motors and generators;
10. distinguish between, and explain the applications of, different protection devices.

NOTES
1. Student Administration will advise students of the dates of their examinations during the semester.

## Important assessment information

1. Attendance requirements:
(i) There are no attendance requirements for this course. However, it is the students' responsibility to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration. (ii) Students must attend and complete the requirements of the Workplace Health and Safety training program for this course before they are able to undertake any practical work in the electrical laboratories.

2. Requirements for students to complete each assessment item satisfactorily:
To satisfactorily complete an individual assessment item a student must achieve at least 50% of the marks or a grade of at least C-. (Depending upon the requirements in Statement 4 below, students may not have to satisfactorily complete each assessment item to receive a passing grade in this course.)

3. Penalties for late submission of required work:
If students submit assignments after the due date without (prior) approval of the examiner then a penalty of 5% of the total marks gained by the student for the assignment may apply for each working day late up to ten working days at which time a mark of zero may be recorded. No assignments will be accepted after model answers have been posted.

4. Requirements for student to be awarded a passing grade in the course:
To be assured of receiving a passing grade in a course a student must obtain at least 50% of the total weighted marks for the course.

5. Method used to combine assessment results to attain final grade:
The final grades for students will be assigned on the basis of the aggregate of the weighted marks/grades obtained for each of the summative assessment items in the course.

6. Examination information:
In a Restricted Examination, candidates are allowed access to specific materials during the examination. The only materials that candidates may use in the restricted examination for this course are: writing materials (non-electronic and free from material which could give the student an unfair advantage in the examination); calculators which cannot hold textual information (students must indicate on their examination paper the make and model of any calculator(s) they use during the examination); Formula sheets.

7. Examination period when Deferred/Supplementary examinations will be held:
Any Deferred or Supplementary examinations for this course will be held during the examination period at the end of the semester of the next offering of this course.

8. University Student Policies:
Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene University policies and practices. These policies can be found at http://policy.usq.edu.au.

## Assessment notes

1. The due date for an assignment is the date by which a student must despatch the assignment to the USQ. The onus is on the student to provide proof of the despatch date, if requested by the Examiner.

2. Students must retain a copy of each item submitted for assessment. This must be despatched to USQ within 24 hours if required by the Examiner.

3. In accordance with University Policy, the Examiner may grant an extension of the due date of an assignment in extenuating circumstances.

4. Electronic submission of assessments is specified for this course. Students are notified of this in the course Introductory Book and on the USQ Study Desk. The due date for an electronically submitted assessment is the date by which a student must electronically submit the assignment. The assignment files must be submitted by 11.55pm on the due date using USQ time (as displayed on the clock on the course home page; that is, Australian Eastern Standard Time).

5. The Faculty will NOT normally accept submission of assessments by facsimile or email.

6. Students who do not have regular access to postal services for the submission of paper-based assessments, or regular access to Internet services for electronic submission, or are otherwise disadvantaged by these regulations may be given special consideration. They should contact the examiner of the course to negotiate such special arrangements prior to the submission date.

7. Students who have undertaken all of the required assessments in a course but who have failed to meet some of the specified objectives of a course within the normally prescribed time may be awarded one of the temporary grades: IM (Incomplete - Make up), IS (Incomplete - Supplementary Examination) or ISM (Incomplete -Supplementary Examination and Make up). A temporary grade will only be awarded when, in the opinion of the examiner, a student will be able to achieve the remaining objectives of the course after a period of non directed personal study.

8. Students who, for medical, family/personal, or employment-related reasons, are unable to complete an assignment or to sit for an examination at the scheduled time may apply to defer an assessment in a course. Such a request must be accompanied by appropriate supporting documentation. One of the following temporary grades may be awarded IDS (Incomplete - Deferred Examination; IDM (Incomplete Deferred Make-up); IDB (Incomplete - Both Deferred Examination and Deferred Make-up).

9. Harvard (AGPS) is the referencing system required in this course. Students should use Harvard (AGPS) style in their assignments to format details of the information sources they have cited in their work. The Harvard (AGPS) style to be used is defined by the USQ Library's referencing guide.
