Balanced Y Configurations (Full Lecture)

In this lesson we'll discuss general 3 phase AC circuit analysis strategies and take a detailed look at balanced 4 and 3 wire Y configured loads in 3 phase AC systems. We'll examine voltage distribution and current flow through balanced Y configured loads and learn that voltage and current magnitude, relative phase shift, apparent, real, and reactive power are identical for each branch impedance comprising the balanced Y configured load. Additionally, we'll learn a balanced configuration carries no current in the 4th neutral wire. Finally we'll learn a balanced 3 wire Y configured load can be effectively treated as a balanced 4 wire Y configuration simply lacking the 4th wire. (Full Lecture) MINOR ERROR @ 39:30 - Total apparent power should have an angle of 20 (not 28) 432VA at 20 correctly resolves into 405.9W and 147.8VAR Copyright information: Use this lecture.
