Answer: The single-phase, two-wire lossless line in Figure

Chapter , Problem 13.8

(choose chapter or problem)

The single-phase, two-wire lossless line in Figure 13.3 has a series inductance L _ 0:999 ? 106 H/m, a shunt capacitance C _ 1:112 ? 1011 F/m, and a 60-km line length. The source voltage at the sending end is a ramp eGt_ _ Etu1t_ _ Eu2t_ kV with a source impedance equal to the characteristic impedance of the line. The receiving-end load consists of a 150-W resistor in parallel with a 1-mF capacitor. The line and load are initially unenergized. Determine (a) the characteristic impedance in W, the wave velocity in m/s, and the transit time in ms for this line; (b) the sendingand receiving-end voltage reflection coecients in per-unit; (c) the Laplace transform of the sending-end voltage, VSs_; and (d) the sending-end voltage vSt_ as a function of time.
