Sample subject outline - Semester 1 2013

Note: Subject outlines often change before the semester begins. Below is a sample outline.

Rationale

It is important to understand how electrical energy is delivered to customers through three phase lines transformers. This unit will assist you to develop competence in computations associated with transients and steady state performance of ac circuits.
This knowledge together with that from the other fundamental engineering units will help you to understand the characteristics of key components of energy delivery engineering systems and how they behave.

Aims

The aim of this unit is to introduce you to electrical energy and how it is delivered to where it is required, through lines and transformers as well as the basics of how it is used in motors.

Objectives

On completion of this unit, you should be able to:

1. Write and apply basic relationships between electrical energy, electrical circuit components, and networks.
2. Analyse transient in ac electrical circuits.
3. Solve problems involving electrical energy, magnetic flux and circuits at an introductory level.
4. Retrieve, evaluate, present and use relevant information to describe the behaviour of simple engineering systems.

Content

1. DIFFERENTIAL EQUATIONS: description of electrical circuits for RLC transients.
2. STEADY STATE ANALYSIS: for single and three phase circuits using phasors.
3. TRANSFORMERS circuits involving transformers and power factor correction.
4. ELECTROMAGNETICS: electric and magnetic fields and relevance to power lines and the basic interactions of currents and fluxes in machines.

Approaches to Teaching and Learning

Teaching Mode: 4 hours per week (plus laboratories)
Lectures: 3 hrs per week
Tutorials: 1 hr per week
Labs: 3 x 2 hour labs in semester.

The delivery of this unit is through lectures, tutorials, formal prac sessions, and informal supplementary learning activities. Lectures and tutorials will be supplemented with a number of informal on-line activities. Supplementary learning resources (e.g. covering some of the underpinning physics) will be provided through video streaming etc.

A diversity of teaching and learning approaches will be used to engage the cohort of students. You will practice problem solving with progressive levels of practice, feedback, challenge, real examples/applications across a range of engineering and physical contexts and practical work. You will be required to synthesise knowledge and skills and actively engage with peers, teaching staff and resources. This unit has practical sessions to develop a good understanding of electrical fundamentals and the basics of motors.

Assessment

Assessment includes problem solving tasks related to electrical circuits, practical laboratory work and an exam. The exam will assess knowledge and problem solving skills developed over the semester in lectures, tutorials and independent learning.You will receive formative feedback on your progress in this unit from marking of the tutorial work and discussions throughout the semester including oral feedback on practical work.

Academic Honesty

QUT is committed to maintaining high academic standards to protect the value of its qualifications. To assist you in assuring the academic integrity of your assessment you are encouraged to make use of the support materials and services available to help you consider and check your assessment items. Important information about the university's approach to academic integrity of assessment is on your unit Blackboard site.

A breach of academic integrity is regarded as Student Misconduct and can lead to the imposition of penalties.

Risk assessment statement

You will undertake lectures and tutorials in the traditional classrooms and lecture theatres. As such, there are no extraordinary workplace health and safety issues associated with these components of the unit.

You will be required to undertake practical sessions in the laboratory under the supervision of the lecturer and the technical staff of the School. In any laboratory practical s you will be advised of the requirements of safe and responsible behaviour and will be required to wear appropriate protective items (e.g. closed shoes or steel capped shoes).

You will undergo a health and safety induction before the commencement of the practical sessions and will be issued with a safety induction card. If you do not have a safety induction card you will be denied access to laboratories.

Disclaimer - Offer of some units is subject to viability, and information in these Unit Outlines is subject to change prior to commencement of semester.
