Calculating from volts to kVA is very simple, in this article you will find how to convert Volts to kVA automatically, only by entering some parameters in the online calculation tool.
To make things easier, some illustrative examples are shown, the formula that must be used, how to perform the conversion in two simple steps and a chart with the most common equivalences.
Formula to convert and change from Volts to kVA:
- I AC = Amps.
- V LL = Line-Line Voltage.
- V LN = Line-Neutral Voltage.
- S (kVA 1Ø) = Kilovoltio-Amperes monofasico.
- S (kVA 2Ø) = Kilovoltio-biphasic Amps.
- S (kVA 3Ø) = Three-phase Kilovoltio-Amperes.
How to convert from Volts to kVA in only 2 steps:
Step 1:
First you must multiply the variables of current (I), voltage LL or voltage FF and the root of three (√3).
Step 2:
The second is to divide the result of step 1 by 1000. For example: A stamping machine has a current of 40.25Amp and a voltage of 208V, to find the kVA multiply 40.25Ampx208Vx√3 and divide the result by 1000 , being of the following form: 40,25Ampx208Vx√3 / 1000 = 14,5kVA.
Examples of conversions from volts to kVA:
Example 1:
A monophasic industrial TV has an amperage of 20Amp and a voltage of 127Volt, how many kVA will the television have ?.
Answer: // The first thing to do is multiply the variables of amps by volts, as follows: 20Ampx127V = 2540, then you must divide the previous result by 1000, in the following way: 2540/1000 = 2, 54kVA.
Example 2:
A three-phase hydraulic pump has an amperage of 23Amp and a voltage of 220Volts, how many kVA will the pump have ?.
Answer: // We must multiply 23Ampx220Voltx√3 and divide the previous result by 1000, the result will be: 8.76kVA.
Example 3:
A hydraulic lift has an amperage of 19 Amp and a voltage of 277 Volts, how many kVA will the elevator have ?.
Answer: // To know the answer, the variables must be multiplied and divided in the following way: 19x277x√3 / 1000 = 9,12kVA.

Note: Previous conversions are made from a 10 Amp amperage and three phase AC power. For different variables you should use the online calculator that appears at the beginning.
How to use the Volt to kVA calculator:
First of all you must choose the number of phases, then you must enter the data that is shown on the left side of the tool, it is important to check what is requested in the table (Bias the type of voltage) because this will depend on the correct result of the calculation, then you must enter the voltage and finally the amperage.
