Essay

In a balanced Y-Y circuit shown below, the magnitude of the line voltage is $\mathrm { V } _ { \mathrm { L } } = 535 \mathrm {~V}$ (rms). The phase impedance is per phase, the wire ipedance is $\mathrm { Z } _ { \mathrm { Y } } = 75 + \mathrm { i } 42 \Omega$ $Z W = 15 + i 11$ Ω per phase, the source impedance is assuing $Z _ { S } = 12 + j 10 \Omega$ $\text { Find } \mathrm { I } _ { \mathrm { A } } , V _ { \mathrm { AN } } \text { and } \mathrm { V } _ { \mathrm { AB } }$ $\angle \mathrm { V } _ { \text {an } } = 0 ^ { \circ }$
