Capacitance of Single Phase Line Transmission Calculator

Calculate the total capacitance of a two-wire (single-phase) transmission line.

Using the formulas:
\[ C’ = \frac{\pi\,\epsilon_0\,\epsilon_r}{\ln\left(\frac{d}{r}\right)} \]
\[ C_{\text{total}} = C’ \times L \] with \(\epsilon_0 = 8.854 \times 10^{-12}\, \text{F/m}\).

Step 1: Enter Transmission Line Parameters

Conductor Spacing, \( d \) (m):

Enter the center-to-center distance between the two conductors (e.g., 1 m)

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

Enter the radius of the conductors (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
