Image text transcribed for accessibility: An overhead line of surge impedance 400 Ohm is connected to a transformer by a short length of cable, 0.1 mile long having a surge impedance of 60 Ohm. A voltage step-wave surge of 100 kV travels along the line towards the cable and transformer. Assume that the transformer termination is effectively an open-circuit, the velocity of propagation in the cable is 105 miles per second, and the overhead line is so long that for the time period of interest the reflection from the other end of the overhead line can be ignored. Figure below shows the analytical expressions for the transmitted voltage at the transformer for the first 3 impingements in terms of the transmission coefficient from cable to transformer and the refection coefficient for the line cable junction. Deduce the resultant voltage at the transformer after a large number of impingements. Plot the transmitted voltage at the transformer over the first 10mu s.
