The first thing you must do is enter the kW you want to convert, then choose the AC or DC current, it is important that once you choose the current you review the data shown on the left of the table, these change according to the current type chosen, then choose the number of phases: 1,2 or 3, this option will only be available if you choose AC current, continue entering the power factor, but if you know you can see the most common below.

#Kw to amp formula for 3 phase generator#
Chart shows the estimated output amps of a generator based on operating power and voltage with 0.8. Typical power factor of common household electronics: Electronics device 3 Phase Generator - kVA / kW / Amp Conversion Chart. Typical Un-improved Power Factor by Industry: Industry For different variables you should use the calculator that appears at the beginning. Note: The conversions of the previous table were made taking into account a power factor of 0.8, a voltage of 220V, with a three-phase AC power.
Table kW a amperes, conversion, equivalence, transformation (Fp = 0.8, volts = 220V, AC, 3F): How many kW: Rta: // You must take the kW and multiply them by a thousand, in the following way: 0.5kWx1000 and then divide the above between the multiplication of the voltage, the power factor and two, as indicated by the formula, leaving the next way: (0.5kWx1000) / (2x120x0.98), which will result in: 2.13A. Generator current ratings based on kilowatt output at 120, 208, 240, 277, and 480 volts three phase AC with a power-factor of. It has a bulb with a power of 0.5kW biphasic (AC), a line-to-line voltage of 208V and a neutral line voltage of 120V, with a power factor of 0.98, what amperage does the bulb have ?. Rta: // The first thing to do is multiply the power in kW by 1000 (9kWx1000), which will result in 9000, then you must divide this result between the multiplication of the voltage by the power factor and root of three, of the following way: 220Vx0,8x√3 = 304,8, finally divide 9,000 / 304 = 29,52A. Rta: // We must multiply the kW by 1000 (1.8kWx1000), to then divide the result between the voltage by the power factor as indicated by the formula for single-phase systems: 1.8kWx1000 / 120 × 0.9 = 16, 67A.Ī three-phase elevator (AC) consumes 9kW, has a line voltage of 220V and a power factor of 0.8, which amperage will have in the elevator ?. We have a monophasic sound equipment – alternating current (AC) of 1.8kW, with a neutral line voltage of 120V and line line of 240V, a power factor of 0.9, how much ampere will the sound equipment have ?. For example, if I have a 220V fridge with a power factor of 0.8, I multiply 220 × 0.8x√3 and get 304.84 ((220 × 0.8x√3) = 304.84.).ĭivide step 1 between step 2. Multiply the corresponding voltage according to the formula by the power factor and by the root of three. For example, if you have a refrigerator that consumes 1.2kW, you must multiply 1,2 × 1000, obtaining 1200, (1,2 × 1000) = 1200. Reference // 2014 ACEEE Summer Study on Energy Efficiency in Buildings / electrical-installation.Multiply the kW by 1000. Single- and three-phase power are both terms describing alternating current (AC) electricity.
Where pf is the power factor, I is the current, V is the voltage and P is the power. Three-phase current I(A) is equal to 1000 times of real power divided by the 3 times of multiplication of voltage between the line to neutral and power factor. Legacy color television CRT-Based color televisionĬomputer monitor Legacy flat panel computer monitor TL DR (Too Long Didn't Read) Perform a three-phase power calculation using the formula: P 3 × pf × I × V. Here in three-phase ac, we multiple power factors with √3. Power factor is the ratio between real powers to apparent power.ĪC three-phase amps to kW conversion formula:Īc three-phase amps to kW conversion formula are similar to AC single phase but power factor value is changed. Conversion of AC single-phase we need to use power factor.ĪC single phase amps to kW conversion formula:ĪC power is equal to the current I in amps multiplied by the voltage V in volts multiplied by power factor divided by 1000.
To convert single-phase, alternating current we use different formulas. To convert DC amps to kW conversion formula:ĭC power is equal to the current I in amps multiplied by the voltage V in volts divided by 1000.
