I suggest you get an elevator with three phase motors or variable frequency drives instead. All the transformer i found dont list a phase conversion? It was always my understanding that balancing the lines would require capacitors. Oh, I didn't mention the case where you might have two hots and no neutral. Suffice it to say 3 phase power provides much smoother torque both running and especially starting.
The primary then draws the same current in two of the lines and the third line carries twice this current. To this you will need a phase converter. An electronic phase converter is technically called an inverter and most catalogs will list this device under that name. The thermal shock of the tungsten going from room temperature to about 5000F is a really doozie on that thin piece of wire. Manufacturers' support can be spotty, so it is recommended to derate the drive by 1 divided by the square root of 3 about 58%. One advantage of this is that most transformers have adjustable taps and this allows you to balance phases a little easier.
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. Wire the low side for 230 and 440, 460 or 480 will come out the high side, depending upon which taps are selected. Important: Modifying existing electrical circuits or installing additional electrical wiring should be done according to local and National Electrical Codes, with a permit and be inspected. They can be had for a song at most auctions and are cheap on crags list. A single coil directly connected to the 220V power supply, see Figure 4. Warning, I have no direct experience doing this. To take a 220 volt single phase system and change it into a 480 volt three phase system, it can not be done.
See how electrical outlets for the home are wired. At our facility we also had to pay a hugeeeeeeeee power factor penalty they referred to as an energy charge, which is why we installed a bunch of power factor correction capacitors. This is rarely to never done with utility power using transformers, but it is routinely done on generators to obtain single-phase power when only a 3-phase generator is available. Many times these contrctors will have some used transformers laying around and can give you a break on the price. The following applies to North American electrical systems.
Somewhere in the neighborhood, there is a transformer with high voltage coming into it. And with the new requirements the ground must face up. One drawback for this method is the output power is reduced toapproximately 66% of the three-phase rating. In other words, it is fixed in terms of the stator. Because it must be programmed, an inverter typically is dedicated to running only one machine 3 phase motor, but with compromises, it can be used to run several 3 phase motors.
Provide details and share your research! Trying to retrofit anything to something other than its intended purpose is hard, expensive, and dangerous. Hopefully I can explain this so it is understandable. That being said, money can make anything happen. You will get an unbalanced load on the transformer if you use multiple taps. It has traveled several thousand miles with me to several power plants that had 480 3 phase only. Before talking about the usage of three phase asynchronous motor being converted to work on single phase power supply, we should explain the issue of establishing single phase asynchronous motor rotating magnetic field, because single phase motor can be started only after the establishment of rotating magnetic field.
Sorry I am little weak electrically. Walt, some information is required before any answers can be recommended. If you mean 220V sin … gle phase with just one hot wire and a neutral, then a larger percentage of 3-phase meters can be used, and will meter accurately. Unfortunately, a static phase converter reduces the available horsepower of the motor by about a third and has difficulty starting air compressors and other machines with heavy starting loads. Power companies like to keep the voltage as high as possible to get the maximum use of their distribution network.
Probe 1: ground to L1, clip to L2. I would only go this way for a backup plan though. Sometimes, neutral to one leg is not same as neutral to another. Ray I beg to differ, Codered741 I agree with RayC who posted just as I did. We would have them set up with a 480v 3 phase plug so we would just plug them into a local electrical outlet. I will be using a qualified electrician. All you need to generate 120 from 480 is a step down transformer that has a center tap for the neutral.
