You have to know the power loading and phase angle (or power factor) between each pairh of the phases, otherwise you could be making serious errors.

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 kvar to amps?
At what voltage? When you know the voltage then, to get the amps those kilovolt.amps contain, you simply divide the kilovolt.amps by the voltage. <><><> You can't convert kVA (kilovolt.amps) to amps unless you know either the source voltage (as was explained above here in the first answer) or the load resistance which is drawing the current from the source. If you know them both you can use Ohm's Law to get the amperage: I = V / R In words, Ohm's law is: Current (amps) equals voltage divided by resistance (ohms)
How many kilowatts does it take to run 100 amp home?
A three wire home distribution service rated at 100 amps has a wattage capacity of;From L1 to L2 at 240 volts x 100 amps = 24000 watts or 24 kilowatts. From L1 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts. From L2 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts.
Single phase 220 volts 2.6 kW how many amps?
You cannot convert 2.6 kw to amps with that information only. In order to convert watts to amps, you also need to know either current or voltage. This is because watts is volts times amps, and volts is current times resistance
How many amps can 30 kva transformer 575 volts to 480 volts gives?
for three phase the calculation is 30,000 = 1.73*V*I - simple as that. For single Phase the calculation is 30,000 = V*I - simple as that It is important to note the voltage in the first line is Line to Line (typically how it is specified in three phase power systems), and the second line it is Line to neutral. A 30KVA transformer is the same as 30,000VA to find out the Amps you need to divide the voltage if the transformer is single phase for example: 30,000VA / 480V = 62.5 Amps The calculation for a 3 phase transformer is the VA / voltage / 1.73 for example: 30,000VA /480V / 1.73 = 36.12 Amps
18 ampers 3 phase 415 volts how much kilowatt?
Volts x Amps = Watts, divide with 1000 and you get kilowatts.
How do you convert 400 amp of three phase supply into kwh?
By knowing the voltage you could use calculate the wattage. Power equals volts times amps. Divide by 1000 to get kilowatts.
You know the voltage and amps how do you convert to kw?
Power is obtained using the equation: Power (Watts) = Voltage (Volts) x Current (Amps) To convert to Watts to Kilowatts (kW), simply divide by 1000 (or shift the DP left by 3 places). eg. 5000W = 5kW Bringing these together: Kilowatts = ( Volts x Amps ) / 1000
How do you convert kva to amps three phase system when you have 220-240 volts?
Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.
How many 12 kw is in amps?
There are zero kilowatts in amps. A voltage value has to be supplied before an answer can be given. I = W/E. Amps = Watts/Volts = 12000/Volts. Alternatively, you could state the resistance, from which the amps are determined from P/R = I2.
How many how many amps in 100 watts?
A three wire home distribution service rated at 100 amps has a wattage capacity of;From L1 to L2 at 240 volts x 100 amps = 24000 watts or 24 kilowatts. From L1 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts. From L2 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts.
What is the formula to convert amps to volts?
Amps and volts are two separate parts of power measurement and do not convert into each other. Multiplying amps times volts will give you the measurement of wattage.
How di you convert kw to amps for a one phase system?
A kw (kilowatt) is 1000 amps x volts. If you assume your one phase system has 120 volts, then divide by 120. Cheap, but close enough for most work, assume 100 volts, then each amp is a tenth of a kilowatt.
How can you convert amperes in to volts?
Amperes does not convert into volts they are two different values. Become familiar with the following formula and look at the relationships between the values. Volts = Amps x Resistance, Amps = Volts / Resistance and Resistance = Volts / Amps.
1 megawatt equals how many amps at 480 volt 3 phase?
The equation you need to find amperage when kilowatts are known. Amps = kW x 1000/1.73 x volts x PF. Use .9 as a Power Factor constant.First megawatts must be changed to kilowatts. 1000000/1000 = 1000 kilowatts. Amps = 1000 x 1000/ 1.73 x 480 x .9 = 1000000/747 = 1338.6 amps.
Convert 6800 watts to kva?
There are a few components missing from your question. I need to know either the voltage or the amperage and the power factor. For single phase, the formula for Kilowatts is Amps x Volts x pf/1000. The formula for Kilovolt-Amperes is Amps x Volts/1000. As you can see more info is needed.
How do you convert VA to Amp?
Multiply the amps by the volts and the answer is the VA
