CET747 Power Quality III

Course Provider

School of Electrical and Electronic Engineering (EEE)



Academic Unit



The course aims to establish and control the voltage variation effects on power systems and power system equipment. The course also focuses on system faults, their effects on voltage variations, and their solutions.

This course is part of:

- Graduate Certificate in Power Engineering
- FlexiMasters in Power Engineering

At the end of the course, learners  are able to:

1. equip the necessary skills to handle the voltage and current variation related problems;

2. identify the cause or source of the problem and assess the severity of each problem with respect to the vulnerability of the affected loads and;

3. use computer modelling and simulations to examine the system responses and evaluate the effectiveness of various solutions.

Voltage Variations

Definitions and measurements
Typical causes and characteristics
Load switching effects and solutions

System Faults and Effects on Voltage
