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. 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. 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.
