2 Objectives Demonstrate the phase relationship among the three voltages or currents in a three-phase system. State the difference between line voltage and phase voltage and convert between them. Show how to reverse the phase sequence in a three-phase system. Show why the neutral current in a four-wire balanced three-phase system is zero.
3 Objectives Explain the differences between a three-phase wye and a three-phase delta system. Calculate power in both wye and delta three- phase systems. Discuss some of the advantages of three-phase systems over single-phase systems.
