SUMMARY
In power transmission systems, the inductance (L) increases with the spacing between conductors due to the interaction of magnetic flux lines. The formula for inductance is given as L = 2 x 10-7 ln(D/r), where D is the distance between conductors and r is the radius of the conductors. As the distance increases, the area for magnetic flux increases, allowing more flux lines to traverse the space, which contributes to higher inductance. This phenomenon is particularly relevant in two-wire AC systems where the mutual flux between conductors plays a critical role in determining inductance.
