The only difference is that the square root of three (3) is replaced by a number three (3), and line-to-line RMS is replaced by line-to-neutral. You can calculate 3-phase power from amps to kW with line-to-neutral voltage just as you would with line-to-line voltage. RLC Resonance frequency calculator: A useful electronics tool for finding the frequency at which a circuit resonates. Kilowatts from Amps (line-to-neutral voltage) kW 3 × PF × A × V / 1000. Solution: I = / = 80.28 Aģ Phase Induction Motor current calculator: A useful calculator to find the FLA and RLA in 3 phase induction motorĮlectricity bill calculator: Used to find the cost of appliances in your bill.Ĥ Band Resistor color code calculator: A useful tool for decoding 4 band resistors.ĥ Band Resistor color coding calculator: Provides the value of 4 band resistor. Find the current if the power factor is 0.9. Three phase kW to Amps calculations involve a ration of 1000 times kW to the power factor times voltage and an additional factor 1.73 that represents an equivalent of √3 and is added because the circuit is three phase in nature.Įxample: A 3 phase 400 volt circuit has a 50 kW load connected to it. Solution: I = / = 31.25 A Three phase kW to Amps Here the formula is identical to the previous one with the difference being a 2 is introduced in the denominator.Įxample: A 200 volt, two-phase circuit operating at 0.8 PF is loaded with 10 kW load. ![]() Solution: I = / = 196 A Two-phase kW to Amps To put it simply, we can get the amps from dividing the kilowatts by voltage and multiply it by 1000. The system is operating at 0.85 power factor. Single phase formula is a ration of thousand times kilowatts to the power factor times operating voltages.Įxample: A 120-volt single phase AC circuit has 20 kW load. The kilowatt-hour, in this case, is nearly 6kWh. Let's say you have an electric device running on a standard 120V circuit for 5 hours. To calculate how many amps in a kW, multiply kW by 1,000, and divide by volts. To put it simply, we can get the amps from dividing the kilowatts by voltage and multiply it by 1000. If you want to convert kWh to Amps, you can use the below formula: Amps (kWh × 1000) (V × H) Where. Kilowatts to Amps is a tool to convert kilowatts to amps. The single phase and all other alternating current circuits introduce an additional concept of power factor in the denominator. DC Circuits kilowatts (kW) to ampere (Amps). calculadora de kW a amperios Utilice e para notacin cientfica. ![]() Solution: I = / 100 = 500 A Single phase kW to Amps It is a ratio of 1000 times kW to the system voltages.Įxample: A 50 kW, 100-volt dc (Direct current) generator power v belt at a cement production power plant. Measurements must be precise when choosing electrical equipment or when working with single or three-phase circuits.If you dont like to count kW and Amps manually we have a solution Our online AC power calculator can help you convert electrical power into current and vice-versa for single-phase and three-phase electric power.
