![]() The formula will solve for current in amp. In Watt’s Law, power is measured in watts and voltage is measured in volts. It means that the phase current in amps is computed by 1000 multiplied by the power in kilowatts divided by the square root of three multiplied by the power factor times the line to line voltage RMS in volts. KW V x A 3Ph (L1 + L2 + 元 ) /3 x 400V x 1.732 x PF/1000. Calculation of AC three phase Kilowatts to amps Line to line Voltage I (A) 1000 x P (kW) / (3 x PF x V L-L (V)). Suppose you want to use a 10-kW unit in a 220v system, the calculation will go like this: 1000 × 10kW 220V 45.45Amps 1000 × 10 kW 220 V 45.45 Amps. L120.8A L221.4A 元21.3A - Reading taken at 6am. To know how many amps is 10kW in DC connection, you need to consider the voltage rating of the system. below is my working out, but it seems high especially when you then add the cost per unit in. So, through this article “ kW to Amps Calculator” we can find amperage from kilowatts if we know the voltage of the circuit using electrcial Watt’s law. that states that current = power ÷ voltage. Then when I have the reading I have to convert it to KW then to KWh. Three phase kilowatts to amps (kW to amps chart) at a P.F. Single phase kilowatts to amps (kW to amps chart) at a P.F. I=2*1000/3*230*0.9= 3.21 Amp DC kilowatts to amps (kW to amps chart) KILO WATT For easier explanation, let us review the example below: We have a circuit with 25kW three-phase power generator, 80 efficiency (0.8 PF) at 240volts. ![]() In the case of AC three-phase supply if watt and phase to neutral voltage is known then ampere rating can be calculated as follow :Įxample: For 2 kW three-phase ac supply and Phase voltage (Phase to neutral)= 230v and PF= 0.9 Hence 2kw= 3.09 Amp AC three phase AC three-phase supply with line to neutral voltage calculation I= P(KW)*1000/ √3* V L-L * Cosθ V L-L= line voltageĮxample: For 2 kW three-phase ac supply and line voltage (Phase to phase)= 415v and PF= 0.9 Similarly, in the case of AC three-phase supply if watt is known then ampere rating can be calculated as follow the same result can be found using above 3 phase power calculator kW to amps : Assumed the PF is 0.5, and supposed the voltage is 110 V, we get these result: DC: I 1000 × 22 kW / 110 V 200 A. Hence 2KW = 9.66 AMP single phase ac supply AC three phase kilowatts to amps calculation From our formulas follows that in order to get 22 kilowatts in amps we must know the voltage. If for any single-phase ac circuit power kW is known then using the following formula and calculation we can easily calculate the amperage and also, we can obtain the same result from the above KW to the amps calculator.Įxample: For 2 kW single phase ac supply and voltage (phase to neutral)= 230v and PF= 0.9 With this tool you can convert kW to Ampere or Viceversa Amp. Watt is the parameter to calculate how much power is consumed by a load and how much power can be delivered to a circuit. AC single phase kilowatts to amps calculation ![]()
