INTRODUCTION

This course is specifically designed for non-electrical engineers who would like to gain an understanding of the basic principles, theories and understanding of electrical engineering work. In this course, the participant will learn how to perform straightforward and common calculations associated with voltage, current, power and power factor. The basic concepts and working principles of electrical machines will also be introduced in this course. The participants will also gain a good understanding of the electrical generation, transmission and distribution systems. Some power quality issues, which is now becoming a big concern to power utility and manufacturers, will also be discussed in here. Some important concepts in electrical safety will also be included.
