Important developments for controlling over voltage and conductor resonances in recent decades has given the possibility of reducing the phase distances in vast range. By this optimization can be made of some of the electric parameters in comparison with normal distribution lines, increasing the capacity in energy transmission. The reduction of the reactance of the line, increasing capacitance, increasing serge impedance loading (SIL) and reduction or increase of some of the other electrical parameters such as the geometric mean distance (GMD), will increase the capacity of this kind of modern distribution lines in comparison to normal distribution lines. By doing this, optimization can be made for different parts of the net. In this paper, a program in windows using Delphi software is presented for this optimization. The electrical specifications of modern and normal distribution lines are compared.
