Inductance of Double Circuit Transmission Line Calculator

Calculate the total inductance of a double-circuit transmission line using the formula:
$L^{'} = \frac{μ_{0}}{π} \ln (\frac{D_{e q}}{r})$
and
$L_{total} = L^{'} \times L$ with $μ_{0} = 4 π \times 10^{- 7} H/m$ .

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

Effective Conductor Spacing,

D_{e q}

(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,

ϵ_{r}

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