Estimate voltage drop and percentage loss from cable length, current, conductor size and material.
Results are for information and preliminary estimation. For critical technical work, manufacturer data, local codes and qualified professional review take precedence.
A simplified DC/single-phase method uses ΔV ≈ 2 × L × I × ρ / A. Temperature, connections, harmonics and local codes can change real results.
Example: Estimate the loss for a 20 m run carrying 10 A through 2.5 mm² copper.
Electrical and energy calculations are not final designs by themselves. Load profile, conductor conditions, protection, efficiency and local codes must be considered together. Sorsana tools are intended for preliminary sizing and scenario comparison.
Excessive drop can affect device performance, efficiency and reliability.
No. Critical installations require qualified engineering and applicable codes.
