Sag of Transmission Line Calculator
Calculate the sag of a transmission line with supports at the same height using:
\[
f \approx \sqrt{\frac{3L(S-L)}{8}}
\]
* Enter the horizontal span \( L \) (m) and the total cable length \( S \) (m). Note that \( S \) must be greater than \( L \).
Step 1: Enter Parameters
Example: 300 m
Example: 310 m (must be greater than L)
