In this video, award-winning engineering educator, Dr. Carlotta A. Berry, introduces three phase systems and sources and analysis of Wye-Delta and Wye-Wye circuits. Upon completion of this lecture, students should be able to briefly define and explain balanced three-phase voltages, wye- and delta-connected sources, wye-delta and wye-wye circuits.
