3 Consider a 100-km lossless single-phase transmission line with series inductance per-unit length of 2e-6 H/m and shunt capacitance of 1.25e-11 F/m. The source voltage at the sending side is a step with 100 kV. At the sending side, the source impedance is pure resistive and is equal to 4 times of the surge impedance of the line. On the receiving side, the load impedance is pure resistive and equal to half of the surge impedance of the line. (a) Find the steady-state voltage on the receiving side. (b) Using the method based on Laplace transformation, find an infinite series representing the voltage of the line as a function of time and distance
