Symmetrical Three Phase Transmission Line Inductance Calculator

Calculate the total inductance using: $L^{'} = 2 \times 10^{- 7} \ln (\frac{D}{r}) (H/m)$ and $L_{total} = L^{'} \times L_{line}$

* Enter the conductor spacing $D$ (mm), conductor GMR $r$ (mm), and line length (km). Values are converted to SI units.
