Calculator Volts to kVA – Formula, examples and chart

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:

formula volts to kva

  • AC = Amps.
  • LL = Line-Line Voltage.
  • LN = Line-Neutral Voltage.
  • (kVA 1Ø) = Kilovoltio-Amperes monofasico.
  • (kVA 2Ø) = Kilovoltio-biphasic Amps.
  • (kVA 3Ø) = Three-phase Kilovoltio-Amperes.

How to convert from Volts to kVA in only 2 steps:

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.
