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
Enter the effective center-to-center spacing between circuits (e.g., 1 m)
Enter the radius of the conductor (e.g., 0.01 m)
Total length of the transmission line (e.g., 100 m)
For air, use 1; for other media, use the appropriate value.
