Generator current ratings based on kilowatt output at 120 and 240 volts single phase AC with a power factor of 0.8 Single phase kilowatts to amps (kW to amps) at a P.F.

You can find the amps value from known kilowatts in the tables below: DC Kilowatts to Amps (kW to Amps). The amps will be:Īmps = 75.18A kW to Amps Conversion Table We have a circuit with 25kW three-phase power generator, 80% efficiency (0.8 PF) at 240volts. To put it simply, we can get the amps from dividing the kilowatts by the product between 3, rms AC phase voltage, and power factor, then multiply it by 1000. If the phase voltage value is already known, we can calculate amps from kW using the formula below: To put it simply, we can get the amps from dividing the kilowatts by the product between √3, rms AC line voltage, and power factor, then multiply it by 1000. The amps will be:Īmps = 52.1A Three Phase AC Circuits – kilowatts (kW) to ampere (Amps) We have a circuit with 5kW power generator, 80% efficiency (0.8 PF) at 120volts. To put it simply, we can get the amps from dividing the kilowatts by the product between rms AC voltage and power factor, then multiply it by 1000. The amps will be:Īmps = 8.33A Single Phase AC Circuits – kilowatts (kW) to ampere (Amps) We have a circuit with 1kW power at 120volts. To put it simply, we can get the amps from dividing the kilowatts by voltage and multiply it by 1000.įor easier explanation, let us review the example below: We have to understand first that:įrom the previous basic power formula, we know that:ĭC Circuits – kilowatts (kW) to ampere (Amps) Besides watt and ampere, we also include voltage measurement in the conversion. We can convert watts to ampere and vice versa directly but converting kW to amps and vice versa can’t be done directly. You might also be interested in our VA to kW calculator.Like stated above, kiloWatts (kW) is the measurement of the power and ampere (A) is the measurement of the current.
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: Thus, the total generated apparent power is not always used for real work due to the power factor converting between them requires a formula. 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. The delivered real power is measured in watts (W) one watt equals one joule of energy supplied to a device in one second. 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. 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.
