Capacitance of Straight Conductor Calculator

    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

    Example: 100 m

    Example: 10 m

    Example: 0.01 m (1 cm)

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

    Formulas:
    \( C = \frac{2\pi\epsilon_0\,\epsilon_r\,L}{\ln\left(\frac{2h}{r}\right)} \)
    with \( \epsilon_0 = 8.854 \times 10^{-12}\, \text{F/m} \).
