Thus, the apparent power S in volt-amps is equal to 1,000 times the real power P in kilowatts, divided by the power factor PF. The formula to convert kilowatts to volt-amps is: DC kW to Amps It is a ratio of 1000 times kW to the system voltages. Enter the known kW and system voltages to find the current through the circuit. Thus, the total generated apparent power is not always used for real work due to the power factor converting between them requires a formula. kW to Amps conversion calculator is used to calculate amperes from the known power kilowatts in DC, Single, two, or three phase AC circuits. The difference between the two is conceptualized by the value of the system power factor, which should ideally be equal to 1. These components have electrostatic and magnetic fields to store energy and require some power loss in terms of reactive power. The difference between generated apparent power and delivered real power arises due to nonlinear elements of the grid, i.e., the capacitive and inductive elements of the transmission network and connected load. One kW of power is equal to 1,000 watts of power. In an electrical power system, power is calculated in a higher unit, kilowatts (kW), due to the large electrical loads connected to the power system at any given time. ![]() 1 1.0 Electrical power consumption ( proc- 12.0 ess only ) kw - hr. The delivered real power is measured in watts (W) one watt equals one joule of energy supplied to a device in one second. 19.0 17 3.9 3.5 10.0 9 2.7 2.4 1.8 1.6 1. The generated apparent power is measured in volt-amperes one VA is equal to the power that would flow when one volt is applied to cause a current flow of one ampere through a device. Line to neutral voltage is the voltage measured between any line and the neutral point.Volt-amps and kilowatts are both measures of electrical power, but they’re slightly different.Įlectrical power is a measure of the instantaneous rate at which electrical energy is generated at the power station and the total energy delivered to an electrical device connected to the power station. Line to line voltage is the voltage measured between any two lines in a three phase circuit.)ĭetermine the phase current I in amps (A) by dividing the power P in watts (W) by 3 times the power factor PF times the line to neutral RMS voltage VL-N in volts (V): The formula states that the phase current is equal to 1000 times the power in kilowatts, divided by the square root of 3 times the power factor and the line. The RMS voltage is the square root of the mean over one cycle of the square of the instantaneous voltage.)Ĭonverting Watts to Amps (AC three phase system)Ĭalculate the phase current I in amps (A) by dividing the power P in watts (W) by the square root of 3 times the power factor PF times the line to line RMS voltage VL-L in volts (V): P(kW) 3 × PF × VL-L(V) This formula relates the phase current I (in amps) to the power P (in kilowatts), power factor PF, and line to line RMS voltage VL-L (in volts). Power factor values can range from 0 to 1. (The power factor is the ratio of the real power flowing to the load to the apparent power in the circuit. (For AC - Three Phase only) Enter voltage type: Line to Line, or Line to NeutralĬonverting Watts to Amps (Direct Current system)Ĭalculating current I in amps (A) can be done by dividing the power P in watts (W) by voltage V in volts (V):Ĭonverting Watts to Amps (AC single phase system)ĭetermine the phase current I in amps (A) by dividing power P in watts (W) by the power factor PF multiplied by the RMS voltage V in volts (V):.Select current type (Direct Current, AC - Single Phase, or AC - Three Phase).Calculate How to use an amperage calculator ![]()
