Three-Phase Power Calculator

How to use it

1. Calculate power activa: √3 × 400V × 32A × 0.85 = 1.732 × 400 × 32 × 0.85
2. P = 18881W = 18.88 kW
3. Calculate power aparente: √3 × 400V × 32A = 22170 VA = 22.17 kVA
4. Convert a HP: 18.88 kW ÷ 0.746 = 25.3 HP

Common mistakes

• ⚠️ Olvidar factor √3 in formula three-phase (Use formula single-phase)
• ⚠️ Not Consider factor of power in cálculos of power activa
• ⚠️ Confusing voltage fase-neutro (230V) with fase-fase (400V)

Worked example

Calculate three-phase power for 32A at 400V with power factor 0.85.

Sistema three-phase of {corriente_a}A a {tension_v}V with FP={fp} tiene power activa of {power_kw} kW ({power_hp} HP). power aparente: {power_kva} kVA.
