Essay

In a balanced $\Delta - Y$ circuit shown below, the agnitude of the phase voltage is V_P = 565V (rms). The wire Impedance is per $\mathrm { Zw } = 17 + \mathrm { j } 11$ , and the phase impedance is $Z _ { Y } = 47 + j 49 \Omega$ per phase. Find line currents and voltages of the equivalent Y-connected source assuming $\angle \mathrm { V } _ { \mathrm { ab } } = 0 ^ { \circ }$
