Module 8: Poly-phase systems

Learning Objectives

  • Become familiar with the magnitude and phase relationship between the three phase voltages in a poly-phase system.
  • Be able to calculate the voltages and currents for a three-phase ∆ and Y-connected generator and ∆ and Y-connected load.
  • Understand how to calculate the real, reactive, and apparent power to a Y- or ∆-connected load.
