Abdul R. Beig    Department of Electrical Engineering, The Petroleum Institute, Abu Dhabi, UAE


This chapter presents the basic concepts and analysis of the balanced three-phase circuit. A brief review of generation of balanced three-phase voltages is presented. The three-phase connection of wye- and delta-connected sources, and wye- and delta-connected loads is given. The analysis of different types of three-phase networks is presented. The calculation of active, reactive, and apparent power in a balanced three-phase circuit is presented.
