Loading Phase Calculator
Calculate electrical load per phase for single‑phase and three‑phase systems. Enter power, voltage & power factor to get current, apparent power, and detailed analysis.
Step 1: Load Details
Understanding Power Factor
Power factor (PF) is the ratio of real power to apparent power. A PF close to 1 means efficient usage. Inductive loads (motors) typically have PF between 0.7 and 0.95.
Step 2: Load Characteristics
About load categories
Select a category to automatically set a typical power factor. You can still fine‑tune the PF value in Step 1.

Electrical formulas
Single‑phase: I = (P × 1000) / (V × PF)
Three‑phase: I = (P × 1000) / (√3 × V × PF)
Apparent power S (kVA) = P / PF | Reactive power Q (kVAr) = √(S² – P²)
