Overview

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.

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.

Course learning outcomes

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;
  11. Communicate technical information in a professional manner.
