This Calctown Calculator calculates the inductance of asymmetrically placed transposed three phase transmission line.

Here µ0 = 4p * 10-7. Please enter the RELATIVE permeability accordingly.

where

GMD = geometric mean distance

L = Inductance of each individual phase

D_{ab}, D_{bc}, D_{ca} are respective distances between the lines

r = radius of line

r^{'} = effective radius

μ_{r} = relative permeability
