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.
