Capacitance of Asymmetric Transposed Three Phase Transmission Line Calculator

Capacitance of Asymmetric Transposed Three Phase Transmission Line Calculator

Calculate the total capacitance of an asymmetric (irregular) three-phase transmission line.

Using the formulas:
\[ C’ = \frac{6\pi\epsilon_0\,\epsilon_r}{\ln\left(\frac{d_{ab}\,d_{bc}\,d_{ca}}{r_a\,r_b\,r_c}\right)} \]
\[ C_{\text{total}} = C’ \times L \] with \(\epsilon_0 = 8.854 \times 10^{-12}\, \text{F/m}\).

Step 1: Enter Line Parameters

Example: 1 m

Example: 1 m

Example: 1 m

Example: 0.01 m

Example: 100 m

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

Formulas:
\( C’ = \frac{6\pi\epsilon_0\,\epsilon_r}{\ln\left(\frac{d_{ab}\,d_{bc}\,d_{ca}}{r_a\,r_b\,r_c}\right)} \)
\( C_{\text{total}} = C’ \times L \)
with \( \epsilon_0 = 8.854 \times 10^{-12}\, \text{F/m} \).
