Ferranti Effect Voltage Calculator
Estimate the open-circuit (no-load) receiving end voltage due to the Ferranti effect.
Formula:
\[
V_R = V_S \left[ 1 + \frac{1}{2}\left(\omega\, C_{total}\, Z_c\right)^2 \right]
\]
where \( \omega = 2\pi f \), \( C_{total} = \text{Capacitance per km} \times \text{Line Length (km)} \times 10^{-6} \) (in F),
and \( Z_c \) is the characteristic impedance.
* Enter sending voltage (kV), frequency (Hz), capacitance per km (µF/km), line length (km), and impedance (Ω).
