$L=0\mathrm{.}2ln(\frac{GMD}{GM{R}_L})m\frac{H}{K}m$

GMD $($Geometric Mean Distance$)$: Different distances between phases.

$GMD=\sqrt[3]{S_{AB}**S_{AC}**S_{BC}}$

GMR $($Geometric Mean Radius$)$: Different distances in the same phase.

$GM{R}_L=D_s$ for single conductor per phase

$GM{R}_L=D_s^b$ for bundled conductor per phase

$GM{R}_L=\sqrt[3]{D_A**D_B**D_C}$ for Double $-$ Circuit
