PREFACE
The purpose of this book is to introduce the concepts of three phase electrical circuit
analysis to undergraduate engineering students, probably in their first or second year of
tertiary education. Its purpose is to supplement the prescribed text book. Some pre-requisite
knowledge of electrical circuits is required, and is reviewed briefly in Chapters 1 and 2,
which cover the generation of AC sources and the analysis of single phase AC circuits.
Those students who are familiar with these concepts can proceed to Chapter 3, but it is
advised that students should read these first two chapters to become familiar with the notation
