# ELE1801 Electrical Technology

 Semester 2, 2021 On-campus Toowoomba Short Description: Electrical Technology Units : 1 Faculty or Section : Faculty of Health, Engineering and Sciences School or Department : School of Mechanical and Electrical Engineering Student contribution band : Band 2 ASCED code : 031301 - Electrical Engineering Grading basis : Graded Version produced : 3 August 2021

## Staffing

Examiner: Joel Kennedy

## Requisites

Pre-requisite: ENG1500 or MAT1500 or ENM1500 or ENM1600 or Students must be enrolled in one of the following Programs: MEPR or GCEN or GEPR

## Rationale

Electrical engineering is founded on the use of electrical and electronic technology to achieve most of our daily needs. To understand how electricity is used to achieve these needs, Electrical Technology aims to develop a working knowledge of electrical components, machines and power supply systems. In particular, an understanding of fundamental electrical principles and the analysis of DC and AC circuits, transformers, motors, generators and three-phase systems, are the focus of this course.

## Synopsis

In this course students will study and apply the fundamental theories and principles which underpin electrical engineering. In addition, students will develop and practice the application of these principles and theories to understand and analyse more complex electrical systems and equipment such as electric motors and generators, transformers, three-phase supply systems and electrical circuit design.

## 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 and induced e.m.f. related to simple 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. Explain the principles of operation power transformers including their equivalent circuit representation and determine optimum performance characteristics;
9. Explain and compare the principles of operation and the applications of AC motors and generators;
10. Analyse and interpret the equivalent circuit of the human body when exposed to electric current and briefly discuss the role of personal 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) It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and 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 assessment item a student must achieve at least 50% of the marks or a grade of at least C-. Students do not have to satisfactorily complete each assessment item to be awarded a passing grade in this course. Refer to Statement 4 below for the requirements to receive a passing grade in this course.

3. Penalties for late submission of required work:
Students should refer to the Assessment Procedure http://policy.usq.edu.au/documents.php?id=14749PL (point 4.2.4)

4. Requirements for student to be awarded a passing grade in the course:
To be assured of receiving a passing grade a student must obtain at least 50% of the total weighted marks available for the course (i.e. the Primary Hurdle), and have satisfied the Secondary Hurdle (Supervised), i.e. the end of semester examination by achieving at least 40% of the weighted marks available for that assessment item.

Supplementary assessment may be offered where a student has undertaken all of the required summative assessment items and has passed the Primary Hurdle but failed to satisfy the Secondary Hurdle (Supervised), or has satisfied the Secondary Hurdle (Supervised) but failed to achieve a passing Final Grade by 5% or less of the total weighted Marks.

To be awarded a passing grade for a supplementary assessment item (if applicable), a student must achieve at least 50% of the available marks for the supplementary assessment item as per the Assessment Procedure http://policy.usq.edu.au/documents/14749PL (point 4.4.2).

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:
An Online Examination is one in which candidates may have access to any printed, written, or online material as well as a calculator.

7. Examination period when Deferred/Supplementary examinations will be held:
Deferred and Supplementary examinations will be held in accordance with the Assessment Procedure https://policy.usq.edu.au/documents/14749PL.

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. Students must familiarise themselves with the USQ Assessment Procedures (http://policy.usq.edu.au/documents.php?id=14749PL).

2. Referencing in Assignments must comply with the Harvard (AGPS) referencing system. This system should be used by students to format details of the information sources they have cited in their work. The Harvard (APGS) style to be used is defined by the USQ library’s referencing guide. These policies can be found at http://www.usq.edu.au/library/referencing
