Inductance of Symmetrical Three Phase Transmission Line Calculator
Calculate the total inductance of a three-phase transmission line (equilateral triangle configuration).
Using the formulas:
\[
L’ = \frac{\mu_0}{2\pi}\ln\left(\frac{D}{r}\right)
\]
\[
L_{\text{total}} = L’ \times L
\]
with \(\mu_0 = 4\pi \times 10^{-7}\, \text{H/m}\).
Step 1: Enter Transmission Line Parameters
Enter the center-to-center distance between conductors (e.g., 1 m)
Enter the radius of each conductor (e.g., 0.01 m)
Total length of the transmission line (e.g., 100 m)
For air, use 1; for other media, enter the appropriate value.
