Asymmetrical Transposed Three Phase Transmission Line Inductance Calculator
This calculator estimates the per‑unit‑length inductance using: $$ L’ = 2 \times 10^{-7}\ln\!\left(\frac{D_m}{r’}\right) \quad\text{(H/m)} $$ with total inductance: $$ L_{\text{total}} = L’ \times L_{\text{line}} $$
* Input the line length (km), the three inter‑conductor distances (mm), and the conductor GMR (mm). Distances are converted to meters.
