Kalkulator Mocy Trójfazowej

Oblicz moc trójfazowego systemu elektrycznego na podstawie napięcia liniowego i prądu.

Wprowadzenie

Three Phase Power Calculator — Calculate power for a three-phase electrical system from line voltage and current. Enter Line voltage (V), Line current (A), Power factor to get an instant, accurate result.

Wzór

Three-phase real power: P = √3 × V_line × I_line × PF, where V_line is line-to-line voltage and PF is power factor (assumed 1 if not entered).

Krok po kroku

  1. Enter the Line voltage (V).
  2. Enter the Line current (A).
  3. Enter the Power factor.
  4. Click Calculate to see your result instantly.

Przykład z życia

Example: With Line voltage (V) = 480, Line current (A) = 50, Power factor = 1, the Three Phase Power Calculator gives Watts: 41569.2194, Power Factor Used: 1.

Często Zadawane Pytania

What voltage should I enter — line-to-line or line-to-neutral?
Line-to-line (line) voltage — this is the standard input for the √3 three-phase power formula, and it's the voltage typically shown on nameplates and utility service specs.
Why is three-phase power preferred for larger loads?
For the same power delivered, three-phase systems carry current more efficiently than single-phase, allowing smaller conductors and steadier (non-pulsating) power delivery, which is why it's standard for motors and industrial/commercial equipment.
What inputs does the Three Phase Power Calculator need?
You'll need to provide: Line voltage (V), Line current (A), Power factor. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Three Phase Power Calculator?
The Three Phase Power Calculator applies the formula exactly as calculated — Three-phase real power: P = √3 × V_line × I_line × PF, where V_line is line-to-line voltage and PF is power factor (assumed 1 if not entered). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Three Phase Power Calculator free to use?
Yes, the Three Phase Power Calculator is completely free, requires no signup, and runs instantly in your browser.

O Kalkulator Mocy Trójfazowej

The Three Phase Power Calculator uses a real, verifiable formula — Three-phase real power: P = √3 × V_line × I_line × PF, where V_line is line-to-line voltage and PF is power factor (assumed 1 if not entered). — so results are accurate every time, not an approximation.
