BALANCED DELTA-WYE CONNECTION
A balanced Δ-Y system consists of a balanced Δ-connected
source feeding a balanced Y-connected load.
Example
Problem: A Δ-connected source supplies power to a Y-connected load in a three-phase
balanced system. Given that the line impedance is 2 + j1 Ω per phase while the load
impedance is 6 + j4 Ω per phase, find the magnitude of the line voltage at the load.
Assume the source phase voltage Vab = 208 ∠0° V rms.
Solution:
