Capacitance of Symmetric Three Phase Transmission Line Calculator

Capacitance of Symmetric Three Phase Transmission Line Calculator

Calculate the total capacitance of a three-phase transmission line arranged in an equilateral triangle.

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

Step 1: Enter Transmission Line Parameters

Example: 0.01 m (1 cm)

Example: 1 m

Example: 100 m

For air, \(\epsilon_r \approx 1\); for other dielectrics, enter the appropriate value.

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