The steady-state voltage drop between the load and the sending end of the line seen in (Figure 1) is excessive Suppose that V-4950/0° V (rms). A capacitor is placed in parallel with the 192 kVA load and is adjusted until the steady-state voltage at the sending end of the line has the same magnitude as the voltage at the load end, that is, 4950 V (rms). The 192 kVA load is operating at a power factor of 0.8 lag. Part A Calculate the size of the capacitor in microfarads if the circuit is operating at 60 Hz. In selecting the capacitance, use the value that results in the lowest possible power loss in the line.

A) Two conductors of a single phase line, each of 1 cm diameter, are arranged in a vertical plane with one conductor mounted 1 m above the other. A second identical line is mounted at the same height as the first and spaced horizontally 0-25 m apart from it. The two upper and the two lower conductors are connected in parallel. Determine the loop inductance per km of the resulting double circuit line.
What do you understand by impedance matching? Also write the formula of characteristic impedance for a loss less line? A piece of parallel wire line has a nominal capacitance of 31.5 F/m, and 9 H inductance per meter. Assume the radius of the conductor is 0.008 meter then find the distance between the two parallel wire lines in milimeter. Note: Please do not handwriting
