Inductance of Double Circuit Transmission Line Calculator

Calculate the total inductance of a double-circuit transmission line using the formula:
\[ L’ = \frac{\mu_0}{\pi}\ln\left(\frac{D_{eq}}{r}\right) \]
and
\[ L_{\text{total}} = L’ \times L \] with \(\mu_0 = 4\pi \times 10^{-7}\, \text{H/m}\).

* Enter the effective spacing, conductor radius, and line length.

Step 1: Enter Transmission Line Parameters

Effective Conductor Spacing, \( D_{eq} \) (m):

Enter the effective center-to-center spacing between circuits (e.g., 1 m)

Conductor Radius, \( r \) (m):

Enter the radius of the conductor (e.g., 0.01 m)

Line Length, \( L \) (m):

Total length of the transmission line (e.g., 100 m)

Relative Permittivity, \( \epsilon_r \):

For air, use 1; for other media, use the appropriate value.
