There are two ways: If the amps are the same on all three phases (voltspp is the phase to phase voltage): amps * voltspp * 1.73 = watts If the amps are different on each phase (voltspn is the phase to neutral voltage): (ampsA + ampsB + ampsC) * voltspn = watts In a 480V system, 480 is phase to phase and 277 is phase to neutral, likewise 208/120, etc. Example - 12A on all phases, 480/277V system: 12 * 480 * 1.73 = 9965W Example - phase A = 4A, phase B = 6.3A, phase C = 2.2A, 208/120V system: (4 + 6.3 + 2.2) * 120 = 1500W

How many watts is 4.75 amp refrigerator starting watts?
To convert amperage to watts, you need to know the voltage, power factor, and the number of phases that you are working with. For a residential refrigerator this is single phase, an industrial refrigerator could be three phase.
Power conversion formula for single phase to three phase conversion?
To convert single-phase power to three-phase power, you can use the formula: P = √3 x V x I x cos(θ), where P is the power in watts, V is the voltage, I is the current, and cos(θ) is the power factor. This formula assumes balanced loads.
How many watts is 1 hp at 480volts?
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.
How do you solve watts to amperes?
Amps = Watts/Volts, or Amps = Sq Root of Watts/Resistance.
How do I calculate the watts used by a service panel using the amps of the three phases do I sum the current and multiply by the voltage or do I average the 3 phases' current x V x 1.73?
To calculate the total power in watts used by a service panel with three-phase power, you would multiply the average current for each phase by the voltage and by the square root of 3 (√3 or approximately 1.73). This accounts for the fact that power in a three-phase system involves the line-to-line voltage and the square root of 3 relationship. So, the formula for total power (in watts) would be P = (Iavg x V x √3).
How you convert the value of single phase power to value of 3 phase power?
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
How do you convert 440 Amps to KVA for three phase system?
You must rephrase your question to make it more specific. <<>> The formula to use to find KVA in a three phase system is, KVA = Amps x Volts x 1.73/1000.
How do you convert single phase kva to three phase kva?
Va=volts x amps. The K stands for one thousand. So 1 Kva is one thousand watts. So 415v times 120a= 49,800 what's. You divide that by a thousand and you get 49.8. So it would be 49.8 Kva.

Power conversion formula for single phase to three phase conversion?

How to Calculate three phase watts with unbalanced phase current?
You will need to determine the power per phase, and add them up to give the total power of the three-phase load. To do this, you will need to multiply the phase-voltage by the phase current by the power factor -for each phase.
If 5000 watts operates 230 volts three phase what will it draw in amps?

How many watts is 1 hp at 480volts?
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.
Why would electric cost more on a three phase system as compared to a two phase system?
Three phase electricity, per watt delivered, is cheaper than single phase. This is because you can deliver the power to an electrical appliance over three "power lines" instead of one. For example, if you tried to operate a 5 hp ac electric motor on single phase it would require 3730 watts for continuous operation and quite a bit more for start up. A 12 gauge standard wire is only rated for 2700 watts. The more current that runs thru a wire the hotter it gets. The hotter it gets the more the resistance (ohms) goes up. Resistance in a wire is pure waste in terms of electrical cost since you are paying to convert electricity to heat. The same motor run on 12 gauge 3-phase wiring would only deliver 1243 watts per electric line to run the 5 hp motor. Also for motor use, three phase is much smoother and "torquier" than single phase since the power pulses to the field magnets is matched far better than in the single phase. For a visual on this see the website description below: = Wikipedia: Three-phase electric power =
How do you solve watts to amperes?
Amps = Watts/Volts, or Amps = Sq Root of Watts/Resistance.
How do convert Million units to megawatt?
It the unit is watts, megawatts is millions of watts, so to convert watts to megawatts, multiply the number of watts be 1,000,000.
