The objective of this unit is to provide students with detailed knowledge of power quality and efficient use of energy resources. Information covered in this unit will include the meaning of power quality, the factors that affect it, the problems caused by poor quality of supply, and the steps to improve power quality. Additionally, energy efficiency at all stages of power generation, transmission, distribution, and utilisation will also be discussed. The discussion will include how to conduct an energy audit, how to detect areas of significant energy loss during the course of the audit, and how to report the findings regarding measures which can improve energy efficiency and their financial viability. Students will also undertake a project involving a power quality/energy audit study for a typical industrial power network.

Learning Outcomes

On successful completion of this Unit, students are expected to be able to:


  1. Explain the basic principles of power quality, causes of poor quality, and their effects.

  2. Discuss the methods available for improvement of power quality.

  3. Establish a mechanism to monitor power quality in a network, interpret the results, and suggest solutions for improvement.

  4. Identify areas of poor energy efficiency in an operation and possible improvement measures.

  5. Establish in quantitative terms – by performing energy efficiency calculations – the actual losses and benefits of efficiency improvement in terms of return on investment.

  6. Outline the process for conducting an energy audit of a facility, and reporting the findings.
