What Is A 3 Phase Power Converter

The electricity in an AC current is not uniformly positive or negative. Instead, the electricity is constantly in flux, changing polarity from positive to negative. If we graphed this polarity change with negative below the zero point on the graph and the positive above the zero, then as you chart the path of the electrons as they move toward the positive and then back to the negative, you would see that they cross the zero line of the graph again and again. When they pass the zero, they have no charge, so they are not c

reating any electricity. Thus every time the electrons pass zero, there is no voltage present. This zero crossing creates the need for 3 phase electricity and, by extension, the need for a 3 phase converter.



Have you ever sung a round? When you sing a round, you usually divide your group of singers into thirds. One group of singers starts. The second group waits until the first group reaches an agreed upon point in the song and then starts singing. A third group waits until the second group reaches the agreed upon point and then starts in. Thus, one group is always at the beginning of the song, one at the middle, and one at the end. This is how 3 phase power works. You have 3 power supplies and each power supply is offset. If the positive end of the wave is the beginning, the zero crossing is the middle, and the negative end of the wave is the end. By offsetting the power supplies you are able to compensate for zero crossing. When one supply crosses zero, one of the other supplies is always at the highest point of its arc. Thus, at any given point in time, you have constant high voltage. The power coming into a home is single phase. Single phase electricity works just fine for small electric motors, but let’s say someone wants to operate a large lathe in their garage or shop in order to turn spindles for custom furniture. A large lathe will require 3 phase electricity, especially when it is working really hard. In order to get the 3 phase electrical supply the lathe needs, a person needs a?3 phase converter.

Basically, the 3 phase power converter takes the single phase electricity coming into the converter and uses it to create 3 phase electricity. One benefit of running a motor on 3 phase electricity is that 3 phase is more efficient than one phase, so by operating his lathe on 3 phase electricity, our furniture builder gets more power and better efficiency than a comparable motor running on single phase electricity. Any large electric motor will require 3 phase electricity, and since power companies do not provide 3 phase current anywhere besides an area that is designated as an industrial area, it is often necessary to use a 3 phase converter to get the 3 phase current required to run a large electric motor. An electric company can actually rig a home or some other building to receive 3 phase current, but it is expensive. For all intents and purposes, it is just easier and more economical to buy a 3 phase current and use it to create 3 phase current wherever it is not readily available. It is probably easiest to find a 3 phase converter on the internet since they are not exactly in high demand at home improvement stores. Rather than make the wild goose chase to the home improvement store, anyone can save themselves time and effort by simply ordering a 3 phase converter online. You will find the best supply and the best selection online, so be kind to yourself and use the internet to satisfy your 3 phase converter needs.


A Licensed Electrician in My House

Here is what one of our readers had to say when we asked about hiring a licensed electrician.

I can’t finish my basement on my own. Some of the work I can do, but when it comes to electricity, I don’t like to mess around. For one thing, I hate the feeling of an electrical shock. I have been shocked a few times on faulty light switches and such, and it has taught me to keep my distance. I also don’t want to have a short somewhere causing me problems. There are just too many ways for me to mess something up. I would rather put my house in the hands of a?licensed electrician.?Electricians?have to be skilled at what they do to in order to wire a house. It is harder than drilling a few holes in the walls and pushing some wire through those holes.

Having too many appliances on the same circuit can overload a circuit. I have been in a house where this was the case. The family had learned that you could only run so many appliances at the same time. They had adapted to deal with the problem, but occasionally they still made mistakes and had to run to turn the breaker back on whenever it got tripped. They did not have the smooth connections and problem-free electrical service that they should have had. They talked about having electricians come to help them with their problem, but they worried about how hard it would be to fix the problem. I thought they should have gone for it, but I did not have a deciding vote in the matter.

Three-way lights are another tricky scenario. You would think that it wouldn’t be too hard to connect two switches to one light, but for some reason it is nearly impossible. I once tried to change out a three-way switch. I figured all I had to do was take out the old switch and observe where the wires connected so that I could easily put in the new switch. Somehow I still messed it up. I tried different combinations of wires again and again, but I just couldn’t figure it out. I thought that since there were only a few possible combinations that I would have to get it right eventually. I didn’t. I had to call an electrician to help me get the switch right. He grumbled about the snarled mess I had left behind. This experience once again taught me to respect electricians and to get out of their way.

I have also known licensed electricians to work with the police. I had a friend growing up who was once called on to help the police figure out how some marijuana growers got their electricity. They had a vast underground growing room lit with grow lights. By tracing their wiring back to the source, he discovered that they had connected their wires before the meter, so they were stealing electricity from the electric company and there was no way for the electric company to tell how much electricity they were using. The police trusted my friend to get the evidence they needed. He had worked with them before, and he always did a good job.

What these examples tell me is that working with electricity is complicated. It takes a specialist to get the job done right. The layman should not get in the way of the electrician even if that layman is a cop. When it comes to finishing my basement, I can do many of the jobs on my own, but there are other jobs that I leave to the professionals. I will trust a licensed electrician to run the wires in my house.
