Single Phase Transmission Line Inductance Calculator

Single Phase Transmission Line Inductance Calculator

Calculate the total inductance using: $$ L_{\text{total}} = \left(2 \times 10^{-7} \ln\!\left(\frac{D}{r}\right)\right) \times L $$

* Enter the line length, conductor spacing, and conductor radius in millimeters (mm). They are converted to meters, and the result is displayed in microhenries (µH).

Step 1: Enter Parameters

e.g., 1000 mm (1 m)

e.g., 100 mm

e.g., 5 mm

Formula: $$ L_{\text{total}} = \left(2 \times 10^{-7} \ln\!\left(\frac{D}{r}\right)\right) \times L $$
(All dimensions are converted from mm to m.)
