A Balanced Three-Phase Circuit is Characterized as follows:
Y-Δ Connected
Source Voltage in B-phase is 20<-90 Vrms
Source phase sequence is acb
Line Impedance is (1+j3)Ω
Load Impedance is (117-j99)Ω
Draw a single-phase equivalent for the a-phase and use it to calculate the a-phase line current and the a-phase line voltage for the three-phase load.
