1/12/2024 0 Comments Kw to amp conversion![]() ![]() The single phase will have three text fields which require you to enter the power in Kilowatts, the voltage in volts, and power factor before clicking on the Calculate button. ![]() Select the current type either the single or three phase according to the units to be converted. In case you want to perform other conversions, you can remove the text fields using the Reset button. If you have a direct current with 10 (kW) and 6 (V), then your current result in amps will be 1666.667 (A). Afterward, click on the Calculate button to initiate the conversion. An additional text field will appear below the voltage in volts text field requiring you to enter the power factor. It can either be an AC-Single phase or an AC- three phase. Selecting the Alternating current will have a different arrangement compared to the DC type of flow. The current result in amps will be projected below the Calculate and Reset buttons. In case you are using the Direct Current (DC), you will be required to enter the power in kilowatts and the voltage in volts respectively in their appropriate cells. It is a conversion calculator that converts the power from kilowatts and voltage in volts to current amps.

Now, if you look at the “1,000 ÷ 1.732V” portion of this equation, you can see that by inserting the respective 3-phase voltage for “V” and multiplying it by 1.732, you can then divide that resulting quantity into “1,000” to get a specific number (or constant) you can use to multiply “kW” to get the current draw of that 3-phase load at the respective 3-phase voltage. If you have a piece of equipment that draws 80A, then you can calculate the relative size of the required power source, which is 10kW (80 ÷ 8.33).īy using this same procedure but inserting the respective single-phase voltage, you get the following single-phase constants, as shown in Table 1.įor 3-phase systems, we use the following equation:Īgain, assuming unity PF and solving this equation for “I,” you get: So, if you have a 10kW load, you can calculate the current draw to be 83.3A (10 × 8.33). Now, if we look at the “1,000 ÷ V” portion of this equation, you can see that by inserting the respective single-phase voltage for “V” and dividing it into the “1,000,” you get a specific number (or constant) you can use to multiply “kW” to get the current draw of that load at the respective voltage.įor example, the constant for the 120V calculation is 8.33 (1,000 ÷ 120). Single-Phase Calculationsīasic electrical theory tells us that for a single-phase system,įor the sake of simplicity, let's assume the power factor (PF) is unity. You can use constants that apply to specific single- and 3-phase voltages to calculate current (I) and kilowatts (kW). No matter what the circumference and diameter of the respective circle, their ratio is always pi. You may ask, “What exactly is a constant?” An example of a constant with which you're very much familiar is pi (π), which is derived by dividing a circle's circumference by its diameter. We'll also show you how you can do these calculations “in your head,” with very reasonable accuracy, through the use of constants. This month, we'll discuss the most fundamental of calculations - those for current (I) and kilowatts (kW). Welcome to the first in a series of articles focusing on electrical calculation basics. ![]()
