The objective of this unit is to provide students with broad knowledge of the many ways the majority of generated electricity is utilised in day-to-day activities. Areas of utilisation covered in this unit include: lighting (illumination engineering); heating (heating appliances and furnaces); electrical welding; electroplating; climate control applications; and, electric traction. Each of these areas includes discussions of several types of devices, their characteristics, and advantages and disadvantages. Students will also undertake a project to design the illumination and heating of a facility in an industrial context. At the completion of this unit, students will have be given the requisite information to work with systems that utilise electrical energy in day-to-day living, and in industrial and transportation operations.
Learning Outcomes
On successful completion of this Unit, students are expected to be able to:
Explain the different types of electrical illumination sources, their control-gear, and compare the relative merits of different sources.
Design a general illumination system based on the accepted principles of aesthetics and visual comfort, and a control system to optimise power usage.
Analyse available electrical heating methods and use simple computations to assess their applications.
Evaluate the different industrial operations using electricity, such as welding and plating.
Analyse using numerical computations the use of electricity in industrial refrigeration and climate control applications.
Explain and compare the different types of electrical traction systems and their applications using appropriate numerical calculations.
