A balanced three phase system consists of the following: 1. Three phase power source which has a phase voltage of $V_L=400?0^{?}$. The power source is $\mathrm{Y}$-connected. 2. Balanced three phase transmission line that has impedance of $Z_{\text{line }}=1+j0.5?$ per phase. 3. Two balanced three phase loads are connected to the power source though the transmission line. The loads have the following specifications: - Both loads are connected in parallel - First load: $?$-connected and has per phase impedance of $Z_{\text{load1 }}=9?j2?$ - Second load: $Y$-connected and has per phase impedance of $Z_{load2}=2+j3?$ Determine the following: A. The per phase equivalent circuit of the balanced three-phase system. B. The line current $I_L$ of the balanced three-phase system. C. The phase current passing through the first load. D. The phase current passing through the second load.
