Consider the transmission line shown in Figure 10.48 with series impedance \(Z_{\mathrm{L}}\), negligible shunt admittance, and a load impedance \(Z_{\mathrm{R}}\) at the receiving end.

(a) Determine \(Z_{\mathrm{R}}\) for the given conditions of \(\mathrm{V}_{\mathrm{R}}=1.0\) per unit and \(S_{\mathrm{R}}=2+j 0.8\) per unit.

(b) Construct the impedance diagram in the R-X plane for \(Z_{\mathrm{L}}=0.1+j 0.3\) per unit.

(c) Find \(Z_{\mathrm{S}}\) for this condition and the angle \(\delta\) between \(Z_{\mathrm{S}}\) and \(\mathrm{Z}_{\mathrm{R}}\).
