Voltage drop from power, single-phase and three-phase current, cable length, cross-section or diameter

With this calculator you will calculate the voltage drops for single-phase and three-phase AC circuits calculated from active power.
You will also calculate cable length, conductor diameter, conductor cross-sectional area, phase or line voltage or active power.

With this calculator you can calculate voltage drops for single-phase and three-phase AC circuits calculated from the rated current. You will also calculate wire length, wire diameter, wire cross-sectional area, voltage or current.
