Capacitance of Straight Conductor Calculator

Calculate the total capacitance of a single, straight conductor (e.g., an overhead line).

Using the formula:
\[ C = \frac{2\pi\epsilon_0\,\epsilon_r\,L}{\ln\left(\frac{2h}{r}\right)} \] where \(\epsilon_0 = 8.854 \times 10^{-12}\, \text{F/m}\).

Step 1: Enter Conductor Parameters

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

Example: 100 m

Height above Ground, \( h \) (m):

Example: 10 m

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

Example: 0.01 m (1 cm)

Relative Permittivity, \( \epsilon_r \):

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