We explain the formula the is supplied in the counter of Volts come kW, we additionally show how to walk from volts to kW in 1 single step , some depicted examples of volts to kW and a table with the key conversions indigenous volts to kW.
You are watching: How many volts in a kilowatt
Most usual power element values in various constructions, appliances and also motors.
Formula to convert, pass, calculate and transform indigenous volts come kW, single-phase, two-phase and also three-phase:
How to transform from volts come kW in 1 single step:
To readjust from volts to kW you only need to multiply the variables displayed in the formula, follow to the type of DC or AC current and the number of phases and also then division by 1000. For example: A biphasic internet server has actually a 120V voltage (AC, LN), a power element of 0.89 and a current of 7.2Amp, how countless kW does the server have actually ?.
To understand the price you have to only take it the formula to find biphasic kW by multiply the variables together follows: 2x120x7.2 x 0.89 = 1.54kW (Formula: kW = 2xV (LN) xIxF.P).
Examples of conversions indigenous volts to kW:
A 3 phase refrigerator has actually an AC voltage that 230Volts (LL), 5.7Amperios and also a power variable of 0.83, how many kW does the vacuum cleaner have?
Rta: // What you need to do is identify the formula to it is in used, because the equipment is three phase and also AC (alternating current), you must use the formula: √3xV (LL) xIxF.P / 1000, replacing the variables would be : √3x230Vx5.7 × 0.83 = 1.88kW.
A biphasic salt luminaire has actually an AC voltage that 240V (LL), one amperage the 7.7Amperes and also a power element of 0.91, which will be the strength in kW of the luminaire ?.
Rta: // examine the formula because that biphasic devices (Formula: kW = 2xV (LN) xIxF.P / 1000), due to the fact that we have the LL voltage, we need to pass it to LN, in the complying with way: main point 220V (LL) / √3 = 138V (LN), this is the method in which the voltage indigenous Linea-Linea come Linea-Neutro is converted, then we simply multiply the variables that show up in the formula: 2x138x7,7 × 0.91 = 1.67kW.
The three-phase voltage in one office is 380Volt (LL), a power variable of 0.84 and also an amperage of 163Amp, how many kW does the office have?
Rta: // together it is a three-phase iluminaicon the formula must be taken: (√3xV (LL) xIxF.P = watts), climate replacing the variables i get: √3x380x163x0,84 / 1000 = 90.12kW.

How to usage the Volts come kW calculator:
Initially girlfriend must select the kind of present you want AC or DC and also the variety of phases in instance of picking AC, climate you must go into the data displayed on the left next of the tool, the is important to review what is asked for in the table due to the reality that follow to what is required, line-line or neutral-line voltage have to be input, climate you must get in the strength factor and also finally the amperage.
