Question:

In a three-phase system, a synchronous generator supplies power to a 200 -volt synchronous motor through a line having an impedance of \(0.5 ot 80^{\circ}\) ohm per phase. The motor draws \(5 \mathrm{~kW}\) at 0.8 p.f. leading and at rated voltage. The neutrals of both the generator and motor are grounded through impedances of \(j 5 \mathrm{ohms}\). The sequence impedances of both machines are \(Z_{0}=j 5, Z_{1}=j 15\), and \(Z_{2}=j 10\) ohms. Draw the sequence networks for this system and find the line-to-line voltage at the generator terminals. Assume balanced three-phase operation.
