b) A 16km long, air-spaced twin wire line has a characteristic impedance of 2500. It connects a 2.2kV DC source (of 2502 output impedance) to a 1500 load. (i) Calculate the total inductance, total capacitance and signal transit time of the twin wire line. (ii) Calculate the voltages and currents of both the forward and reflected waves along the twin wire line, and also the load power. c) The twin wire line develops a sudden short circuit at its midpoint. Describe fully and quantitively the subsequent changes in voltages and currents at all points along it in response to this fault, noting the times at which these changes occur, until steady-state conditions are attained.
