Amps to kVA Calculator

Amperes to Kilovolt Ampere Conversion Calculator

Select phase #:  
Enter amps: A
Enter volts: V
   
Result in kilovolt-amps: kVA
It is an online calculator which converts the Amps and voltage in volts to the Kilovolt-amps. It is simple to operate and requires you to enter the appropriate units in the text fields. The Calculate button executes the calculations once the cells have been filled completely. The first step is to select the phases which can either be a single phase or a three phase.

You will then enter the current in amps and the voltage in volts respectively in the required text fields. The calculator executes the conversion in a single click of the Calculate button. In case you want to perform new calculations, you can erase the entire cells using the reset button.

For example, if you have 100 amps and 240 volts in a single phase, you will enter them correctly in their required cells before clicking on the Calculate button. Your result in Kilovolts-amps will be 24 (kVA). If you need to perform another conversion, you will use the reset button to erase everything in the cells.

In a situation where you have 150 Amps and 300 Volts, and you wish to convert them to Kilovolts-Amps, you first select three phase option before entering the current in amps. You will be required to choose the voltage type which can either be line to line or line to neutral.

Fill in the voltage in volts in the next text field below the voltage type before clicking on the Calculate button. Your results in Kilovolts-Amps will be 77.942 (kVA). You will follow the same procedure while when you want to calculate using the line to neutral as your voltage type.

The first thing to do is to click on the reset button which ensures that all the text fields are empty.

There are formulas which the calculator uses in performing the conversions;

Calculation of Single phase amps to kVA
S (kVA) = I (A) x V (V) / 1000, which means that the apparent power in Kilovolt-amps is calculated by multiplying the current in amps with the voltage in volts and dividing the results by 1000.

Calculation of three phase amps to kVA
Line to Line Voltage
S (kVA) = √3 x I (A) x V L-L (V) / 1000, which means that the apparent power in Kilovolts-amps is calculated by the square root of three multiplied by the phase current in amps by the line to line voltage RMS in volts dividing it by 1000.

Line to neutral Voltage
S (kVA) = 3 x I (A) x V L-N (V) / 1000, which means that the apparent power in Kilovolts-amps is calculated by multiplying three times the phase current in amps by the line to neutral voltage RMS in volts dividing the results by 1000.
