The per-phase impedance of a short three-phase transmission line is \(0.5 / 53.15^{\circ} \Omega\). The three-phase load at the receiving end is \(1200 \mathrm{~kW}\) at 0.8 p.f. lagging. If the line-to-line sending-end voltage is \(3.3 \mathrm{kV}\), determine

(a) the receiving-end line-to-line voltage in \(\mathrm{kV}\)

(b) the line current. Draw the phasor diagram with the line current \(I\), as reference.
