A balanced three-phase source and a balanced three-phase load are interconnected by a three-phase transmission line. The load draws an average power of \(P_{\mathrm{L}}=45 \mathrm{~kW}\) at a lagging power factor of 0.8 and the source produces a complex power of \(S_{\mathrm{S}}=(45 \cdot 2+j\) 35.4) kVA. Find the transmission line wire impedance when the magnitude of the line current is \(I_{\mathrm{L}}=18 \mathrm{~A}(\mathrm{rms})\).
