What the Heck is Three-Phase Power and how can you get some? The old shop had it and the new shop doesn’t. So what the heck is three-phase power and how can you convert machinery to go from the more common single-phase to three-phase and vice versa? For us, the impact was limited because only the air compressor had a three-phase motor. Some of the welding equipment had been running on three-phase, but can easily be re-configured to run on either three-phase or single-phase. But first, a short explanation of three-phase power. Alternating current does just as it’s name implies and alternates cyclically, first flowing in one direction in a circuit and then reversing to flow in the other. As it does this, the magnitude of the voltage supplied varies continuously between a positive and negative maximum amplitude. In the US and anywhere else with 60Hz power, this cycle happens 60 times per second.

My grandfather did have 3-phase power in his house. There are other NEC rules that limit things in residential, such as voltages serving lights. Three phase to a small residence is rare in USA, though common to large mansions. Three phase is more common in other countries, including Israel. It is volts relative to ground. Modern electronic devices using switch mode power supplies with volt input, like nearly all computers, would handle it fine if you have it.

OP 5 Jul 07 Does the model you have in mind sum all 3 phases as well as neutral? If yes, then single phase loads should not bother it. However, another part of my problem is where to find such a device. I had found a GFCI that claimed to work for V 3-phase, but it has very limited documentation and is a bit of a black box. As far as I can tell, it seems like it is assuming a delta load and input for that mattter , as it functions correctly for a three-phase load, but trips when any V single phase load is connected.
Anyone know of a GFCI that would work in this situation? Mostly at V you get breakers with ground fault functions built in, but again I do not think they are commonly as sensitive as GFCI. What is the purpose of the ground fault protection – for operator safety or equipment protection? If you are just trying to detect ground faults, a molded case breaker with a solid-state trip unit including ground fault would do what you want, but you would need a neutral sensor in addition to phase sensor.
If you are trying to match the function of a standard single-phase GFCI breaker or receptacle, that is another matter. These operate at a much lower current level to prevent electrocution. Best bet for this would be to add GFCI receptacles or breakers for your single-phase loads downstream of the three-phase breaker.

Those who don’t study the past will repeat its errors. See Drawings I was running my Drill to mount some new lighting when I noticed my drill speeding up and Slowing down ,after shutting off the drill and measuring the main terminals in the breaker panel I was getting volts from a line that was to only supply volts. I started tracing out the conduit feeding this breaker panel when I found a large shut off switch.
1 review of 3 Phase Electrical Services “Me and my husband recently bought a hot tub and hired 3 Phase Electrical Services to hook it up. They did a fabulous job!! Even squeezed us in on a booked Friday so that we could have it working before the 5/5(2).
Posts Things depend on which end of the wire you are on. Panels are always wired ABC, clockwise rotation. Once you hit the utility side, there’s a lot of difference of opinion and color coding. Most utilities I’ve run across go with red, white, blue orientation left to right in a padmount or on a cluster mount transformer bank. When it gets to the customer end, whatever the rotation is at the service connection that gives the customer what they need is how it’s labeled, generally either ABC or CBA.
The high leg is predominantly marked white, and is labeled as B phase.

I know that phases A and C to neutral you get and that phase B to neutral you get I also know that between any two phases you get My question is why don’t you get volts from phase B to either phase A or C? I believe it has to do with the was the sine waves are off from each other but am not totally sure. Does any one have a good explaination?
Or maybe a diagram of the sine waves? If so we invite you to join our community and see what it has to offer.

I need a quick course in phase converters. An english is not my first language got my number from a friend. He does grainte countertops, and has this huge programable saw from China. The saw is 3 phase, and the breaker inside is amps. He has tried to install a 15 hp converter, but messed it up, and now has a 40 hp converter to hook up. I want to make sure the the customer understands what he needs.

Wiring your Philippine house. As part of our project to build our house in the Philippines, we had to learn about Philippine residential electrical systems. As with our other writings, we do our best to chronicle our missteps as well as our successes, so that our readers get slice of reality about coming to the Philippines and building a house, not a fairy tale.
The transformer serving our house Our pole-mounted meter. From the standpoint of electrical engineering theory, the Philippine system is similar to that used in the U. From the utility pole to the residence panel box we have one or two load wires and neutral conductor. We have a ground earth provided by the homeowner. Looking at how things were done when we built our Philippine house may help other considering house building in the Philippines to get an idea how things are done here.
The Philippine electricians we have met have been quite professional. Wage rates are negotiable and far more reasonable than in your home country. We hope this essay will be of help in making you a more knowledgeable home builder. This from Schneider Electric helps explain the purpose and nature of each of the three conductors. This simple model is appropriate for DC systems but does not work for an AC system because the flow of the power is continually reversing direction with a frequency of 50 or 60 times per second.

The open delta three phase service By Paul Thurst, on February 27th, 5 comments Several months ago, I drove up to an FM transmitter site, looked up at the utility pole and saw this: Three Phase open delta transformer bank Three phase open delta is a bad hombre. Most, if not all, transmitter manufactures will void the warranty of any transmitter connected to a service like this.
What is perplexing is it appears that all three phases are available on the primary side, why would this be necessary? Perhaps it was not always so at this location. Regardless, this was the source of power for 20 KW FM transmitters since until we moved it to a new building last month. According to a GE publication on transformers, open delta 3 phase power is undesirable because: Although this connection delivers three-phase currents which are approximately symmetrical to a three-phase symetrical load, the currents flowing in the high voltage circuit are not equal nor are they degrees apart.
The system is grossly unbalanced, both electrostatically and electromagnetically. Schematically, it looks like this: Hook up a high leg to a single phase volt piece of equipment and wait for the power supply to blow up. Also true with volt lighting circuits, as my assistant once found out with the Coke Machine in the break room. New 3 phase service will almost invariably be wye unless there is some very compelling reason, which is fine.
