Web31 jul. 2024 · V * l / 1,000. In the example above, you would multiply 150 by 50 to get 7,500 and then divide that number by 1,000 to get 7.5 kilowatts. The last step is to convert the figure in kilowatts to kilovolt-amperes. When you do that, you’ll need to divide by 0.8, which represents the typical power factor of a load.
