Quick answer
Three phase power equals √3 times line voltage, line current and power factor.
P = √3 × V × I × PF
How to use the Three Phase Power Calculator
- 1Enter line-to-line voltage.
- 2Enter line current.
- 3Enter the load power factor.
Frequently asked questions
Why does power factor matter?
Low PF means you draw more current for the same useful power.
Is 400 V standard?
Yes in most of Europe; 208 V or 480 V in North America.
