Electrical efficiency is usually expressed as a power factor inbetween 0 & 1, therefore the closer the power factor is to 1, then the more efficiently the kVA is being converted into actual kilowatts. When you know this it is easy to convert kVA to kW becasue you know the efficiency level of the electrical system in question. Most 3 phase generators have a power factor of 0.8. A term called apparent power (the absolute value of complex power) is equal to the product of the volts and amps. Whereas volts is a measurement of electrical pressure, and amps is a measure of electrical current. However in reality electrical systems are not 100% efficient and so not all of the system's apparent power is being used for useful work output.įundamentally, 1 kVA is equal to 1,000 volt amps. ![]() On the other hand kVA (kilovolt-amps) is a measure of apparent power: it describes the total amount of power being used by a system, for example in a 100% efficient system kW would equal kVA exactly. Therefore we can refer to kW (kilowatts) as actual power, it is the amount of power that is converted into an output. Use our handy calculator below to quickly convert kW to kVA, or to convert kVA to kW: Actual Power Enter the current in amps (A), voltage in volts (V), select power factor (PF) from 0 to 1 with a 0. The current I in amps (A) is equivalent to multiple times the power P in kilowatts (kW), separated by the voltage V in volts (. ![]() For example, find the current of a circuit. ![]() A kilowatt (kW) is a much more common term and is how electrical items in your home are rated, you may even notice it quantified on your electricity bill so it is much more relatable, but what exactly is kVA, why is it used and how is it calculated? kVA Calculator The current I in amps is equal to the power P in kilowatts divided by the voltage V in volts. Outside the generator industry, the term kilovolt-amperes (kVA) is not well known. Power ratings are expressed in different forms such as watts and kilowatts, amperes or amps, volts, and also in kVA, But what exactly is kVA? The kVA Power Rating AC single phase kilowatts kW to amps calculation formula. By The ADE Power Projects Team June 15, 2017
