Ampere to kVA
Calculator and formulas for rated electrical power from current and voltage
This function calculates the power rating in VA from the current and voltage. Enter the current in amperes and the voltage in volts. As a result you get the power in kVA.

Power rating formula
1 Phase
\(\displaystyle Power= Voltage × Current \) ⇒ \(\displaystyle P_{(VA)}= U × I \)
Example
\(\displaystyle P= U × I = 230 × 10 = 2300\;W =\color{blue}{2.3\;kV}\)
3 Phasen
\(\displaystyle Power= \sqrt{3}× Voltage × Current \) ⇒ \(\displaystyle P_{(VA)}=\sqrt{3} × U × I \)
Example
\(\displaystyle P= \sqrt{3} × U × I = 1.732 × 230 × 10 = 3983.6\;VA =\color{blue}{3.98\;kVA}\)
