How does the Three Phase Calculator work?

Three sinusoidal voltages 120° apart Then: Line voltage = phase voltage × √3 Then: Line current = phase current (Y-connection) or √3 × phase current (delta) Then: Power = √3 × V × I × PF.

Can you give an example of how to use the Three Phase Calculator?

Example: Input Line voltage 480V gives a result of Phase 277V.
