Voltage Drop formula for Single Phase and DC Circuits.

VD = I × (2 × L × R / 1000)

Voltage Drop Calculation and formula for Three Phase system.

For 3 Phase 3 Wire system.VD = 0.866 × I × RVD = 0.866 × I × 2 × L× R/ 1000

For 3 Phase 4 Wire systems.VD = 0.5 × I × RVD = 0.5 × I × 2 × L× R/ 1000 Where,

VD = Voltage Drop in Volts.I = Wire Current in Amperes.R = Wire Resistance in Ohms (Ω) [Ω/km].L = wire distance in meters.
