Given That Line-To-Ground Voltages Of $V_{a g}=280 \angle 0^{\circ}, V_{b g}=250 \angle-110^{\circ}$

Essay

Given that line-to-ground voltages of $V_{a g}=280 \angle 0^{\circ}, V_{b g}=250 \angle-110^{\circ}$ , and $V_{c g}=290 \angle 130^{\circ}$ volts are applied to a balanced- $\Delta$ load consisting of $(12+j 16)$ ohms per phase. The load neutral is solidly grounded. Draw the sequence networks and calculate $I_{0}$ , $I_{1}$ , and $I_{2}$ , the sequence components of the line currents. Then calculate the line currents $I_{a}, I_{b}$ , and $I_{c}$ .
