kVA Calculator
Calculate kVA (kilovolt-ampere), current, and power requirements for single and three-phase electrical systems. Plan your electrical load distribution efficiently and safely.
Step 1: Power Specifications
230 V
Standard Power Factors
Residential: 0.8-0.95, Industrial: 0.85-0.9, Commercial: 0.9-0.95. Single-phase systems typically use 120V or 230V. Three-phase systems use 208V, 400V, or 480V.
Step 2: Load Specifications
20%
kVA Calculation Formula
Single Phase: kVA = (kW ÷ Power Factor) ÷ 1000. Three Phase: kVA = (kW ÷ Power Factor × √3) ÷ 1000. Always include a safety margin for startup currents and future expansion.
