The formula to calculate Kilovolt-Amps (kVA) from Amps (A) is:
For Single Phase:
\[ S (\text{kVA}) = I (\text{A}) \times V (\text{V}) / 1000 \]
For Three Phase:
\[ S (\text{kVA}) = \sqrt{3} \times I (\text{A}) \times V (\text{V}) / 1000 \]
Where:
Amps (A) is a unit of electric current, representing the flow of electric charge. Kilovolt-Amps (kVA) is a unit of apparent power, representing the total power in an electrical system. The conversion from amps to kilovolt-amps depends on the voltage and whether the system is single-phase or three-phase.
Let's assume the following values for a single-phase system:
Using the formula:
\[ S = 10 \times 230 / 1000 \]
\[ S = 2.3 \text{ kVA} \]
The Apparent Power (kVA) is 2.3 kVA.
