How do you get 480v 3 phase from 220v single phase?
If you were trying to obtain a 220 voltage from a 480 volt three phase system it can be done with a transformer. To take a 220 volt single phase system and change it into a 480 volt three phase system, it can not be done.
Depending on the amount of money you want to spend to make this happen there is a device on the market called a VFD ( Variable Frequency Drive). On the three phase input terminals you apply your single phase voltage. On the output terminals you connect your three phase motor. When run in this configuration there is an internal switch that has to be changed to let the VFD know that it should be looking for only two lines on the input to be hot. Other wise the VFD thinks that there is a line loss on the three phase input terminals and the unit will not start.
Actually, this is not true. You can go from 220 volt single phase to 480 volt three phase but in a rather cumbersome way. You would first need a phase converter - they have solid state VFD's that will go from single phase to three phase or you can build a simple rotary phase converter. After the phase converter, you will have 208/220 volt three phase power. From there you need a power transformer to step up the voltage.
Remember you have to know whether you want delta or wye configured transformers!
get a 480 to 220V transformer, wire one phase of 480V to the primary side of the transformer, than the secondary will give you the output for 220V.
Answer for USA, Canada and countries running a 60 Hz power supply service.You use a single phase 480 to 240 volt step down transformer. Connect the primary across the 480 volts and your load across the 240 volt side. Make sure that the transformer has a high enough capacity to carry the load with out getting into an overload condition. The proper size fusing of this transformer can be done on the primary side of… Read More
Answer for USA, Canada and countries running a 60 Hz supply service. To convert 480 volts single phase to 240 volts single phase you will need to use a step down transformer. Any two legs of a three phase system is classed as single phase. The primary side connection will be any two legs of a 480 volt three phase system. H1 to H2 will be 480 volts. On the secondary side of the transformer… Read More
Two phase systems are no more. They were replaced by the three phase system which is what we use today. If you are talking about drawing 220 volts from a three phase system then all that has to be done is use any two of the three phase legs. When this is type of connection is used it is known as taking single phase from a three phase system. In North America a common three… Read More
You will need to use a transformer. This is because the phase voltage for a three-phase system with a line voltage of 480 V is 277 V.
Any two legs of the 480V will give you 240 V Single phase. I apologize for the wrong information here. A friendly member reminded me of the correct answer. I stand corrected. Any two legs would be at 480 single phase. One leg to neutral will give you 277volts not 240 (408/1.73). You would need to install a step down transformer on the 277v line to achieve 240v.
A 220 single phase has two hot wires and a ground wire (green). You need one of the hot wires, a netural wire and a ground wire to make a 110 circuit. Now the 220 has a hot and a ground but no netural so you have to make a netural out of a separate wire. There are a lot more things to know and do, IE. safety first always disconnect the power and lock… Read More
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 vThe above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
For a three-phase, three-wire, system you will obtain a single-phase supply between any two line conductors. For a three-phase, four-wire, system you will obtain a single-phase supply between any line conductor and the neutral conductor. <><><> As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself, on electrical circuits… Read More
A single phase supply has two wires, a 3-phase supply has four wires, although high-voltage 3-phase distribution can be done with three wires. If the voltage is quoted as 220 v it is most likely to be a single-phase supply.
No, you cannot get a three phase supply directly from a single phase supply. Nowadays electronic inverter units can be bought that will do the job. For very low power loads the cost of such invertors is quite reasonable but for high power loads they are very expensive. For high-power industrial uses the most economical solution is to have a 3-phase service installed by the local electric power utility company.
If you have three adjacent houses each with a single-phase supply taken from different phases in a three-phase cable in the street, the total power is equal to the sum of the powers in each of the three phases.
In the USA, yes it is single phase, running 180 degrees apart. And just FYI single phase and split phase is the same thing. This can be confusing.
Use a 3 phase inverter that works off a single phase supply
It will turn but it will run at about 5/6 of the normal speed, it might overheat even on light load because of increased losses in the iron core of the magnetic circuit, and its oiwer output might be somewhat impaired.
If you have both 220V 3 phase power and 110V single phase power can it be converted to 220-240V single phase power?
If you have a 220v three phase delta system, the phase-to-phase voltage is 220v single phase; hence, no conversion is necessary. Don't worry about 220-240v rating, the voltage rating is nominal. Your 110v single phase has actually already be taken from a center-tapped transformer on your three phase system.
It could be done electronically but true two-phase supplies have not been used for around 100 years. A two-phase supply consists of two single-phase supplies with a phase-difference of a quarter-cycle between them. Two-phase can provide a rotating magnetic field in an induction motor. Two-phase was replaced by three-phase in the early 20th century, and it also provides a rotating field, an advantage that is combined with other big advantages that two-phase does not provide… Read More
The incoming single phase line is in series with all three contactor contacts. For example; Incoming supply line to the top of A phase contact. From the bottom of A phase contact to the top of B phase contact. From the bottom of B phase contact to the top of C phase contact. From the bottom of the C phase contact to the overload block and then to the motor connection box.
You will need a stepdown transformer to convert 3-phase 480V down to 120V. An electrician is going to have to do this. AnswerIt depends on the country in which you live. In European countries, for example, a 230-V single-phase supply is obtained between one of the three line conductors and the neutral conductor. No transformer is necessary, as European three-phase, four-wire, systems operate at 400/230 V.
You need to buy a "single to three phase converter"... Google it, they are easy to find. .
Inspect all motor labels and see if they are dual voltage motors. If they are, they should have a label on them telling you how to convert the motors for 480 volt. This is a relative simple task. Converting to 480 volts will lower the motor current to half of the 230 volt rating, so you will have to change the overload heaters in the individual motor starters. You need to do this to protect… Read More
I depends on what you are connecting to it but you only need 1 of the phases providing you can get to a neutral
With a single phase motor driving a 3 phase generator. It is possible to do it electronically, but that would more expensive and the more the power requirement is, the more expensive it would be.
Yes, that's possible, but only for low-powered motor. You know that in order to start, the stator must be supplied with voltages that are shows shift phase between them, so the trick is to use a capacitor (since it shifts phase current) to simulate a 3-phase source. As indicated in the following picture: http://freecircuitdiagram.com/wp-content/uploads/2010/10/Enabling-3-Phase-Motor-Operates-with-Single-Phase-Supply.gif
You can't, you need three phase power or it won't work.
A 450v 3-phase 4-wire supply has a line-to-neutral voltage of 260 volts so a single-phase supply can be taken from one of the three lines and neutral. Then a 260/110 volt transformer is needed. The voltages are dangerous so ask an electrician if in any doubt.
If you are asking whether you can connect a three-phase motor to a single-phase system, then the answer is no.
Three phase is not converted to single phase. On a 240 volt three phase service 240 single phase can be taken from it. Any two legs from a three phase service is classed as single phase. L1 - L2 = 240 volts. The same is true with L2 - L3 = 240 volts and L3 - L1 = 240 volts.
Simply you don't. To make a single phase supply into a 3 phase supply is going to be expensive. The old way was with a roto-phase unit. Google definition. The latest way is with a VFD (Variable speed drive). Connect the input side of the VFD to single phase voltage and receive three phase voltage on the output side. The last installation I did like this, the VFD cost about $1000. As you can see… Read More
You cannot obtain a three-phase supply from a single-phase system without using some sort of rotary converter.
First of all, your power source must be 3-phase if you want to run the motor, then you need a step-down 3-phase transformer to give 220v 3-phase output.
You should be able to use it as is (assuming the plug matches your outlet). It will just run a little bit cooler at 220 volts vs. 230 volts.
If the single line is compared to another single line and the voltage that you need is correct then you are looking as a singly phase supply. The electrical classification of single phase is that any two legs of a three phase supply can be called single phase. Look on the nameplate of the distribution panel. There it will state what the panel is, either single phase or three phase. Look at where the distribution… Read More
Answer for USA, Canada and countries running a 60 Hz supply service.A three wire system uses two lines L1 and L2 and a Neutral. You can obtain a 120 volt potential from L1 to N or 120 volt potential from L2 to N. Between L1 and L2 you can obtain a potential of 240 volts.
Your question should read, 'How do you convert three-phase to single-phase?' Single-phase can be obtained by connecting a single-phase load between any two of the three line conductors, or between any line conductor and the neutral conductor -depending on the level of voltage you require. There is no conversion necessary, any two legs of a three phase system will give you single phase. Take a 3 phase 208 volt grounded wye system. Any two of… Read More

It will be single phase as there is no common three phase 110 volt systems.
There is no conversion that needs to be made. Any two legs of a three phase system is considered to be classed as single phase. Use legs L1 - L2, L2 - L3, L3 - L1.
If you're asking this question, you should not be attempting this yourself. Period. Hire a professional licensed electrician. More answers For a three-phase, four-wire, system, a single-phase supply can be obtained by simply connecting that load either (a) between any pair of line conductors (there is no such thing as a 'phase' conductor!), or (b) between any line conductor and the neutral conductor. Of course, the voltage rating of the load much then match whichever… Read More
If the generator is a 12 lead reconnectable, you can use something called a zig-zag connection. Check the link below. It is an installation manual for a Marathon generator. Zig-zag connections are shown on page 8. For a home, you would use the low zig-zag connection for 120/240V (in the US). One caveat: you can only load a zig-zag single-phase connected generator to a maximum of 66% of its rated load. So, a 15kW 3-phase… Read More
The best way is to use 6 diodes in a full-wave rectifier. Each diode has one end connected to one of the phase wires, and they are connected so that the positive ends of three of the diodes go to the + terminal and the negative ends go to the - terminal of the DC. This is the way a car alternators are wired up to the battery.

No. Three phase power must be supplied to you from your electric utility, or you can get a phase convertor.
The same way the electric company does it: connect your appliance between one of the three lines and the neutral wire.
One hamster vs. three hamsters.
you have to provide transformer that capable to handle the 380v in to a 220v.
There are two ways. 1: You don't. 2: Use a motor/generator or something designed for the purpose. Normally we get both of these from 480 or higher voltage 3 phase power.
How can you get 240V single phase power from a 240V 3 phase service Can you just connect to two poles of the 240V 3 phase service?
I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect.As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then… Read More
