Field Calculators

Voltage drop, transformer sizing, and sag-tension estimates using real conductor specs. Rough field reference — not a substitute for engineering design.

Resistive approximation only. This calculates voltage drop from DC conductor resistance alone — it does not account for inductive reactance, power factor, or conductor spacing/geometry, all of which affect real AC voltage drop. Treat this as a rough field estimate, not an engineering design value.
