Welcome to today’s edition of your Edmonton electrician. This is where we bring customer service back to the trades.

In today’s tradition, uh, of your Edmonton electrician, we’re going to be talking about three phase power. As always here at Howard power electrical. We are happy to answer our customers questions, concerns. If you have an electrical concern or electrical topic, maybe an electrical issue that you want to hear about, uh, we want to hear about that.

We want to, uh, give you, give you the most information that we possibly can. That’s just another part of our customer service, what we do. And that’s why we make these videos to try and help you guys out. So as your professional Edmonton electrician, our mission is to provide you with exceptional power. And we do this through customer service and we do this through these videos.

So today we want to talk about three phase power and single phase power. A two phase power, which uh, that’s not really fully correct if you want to call it two phase shore, but you should know what it’s really called because it’s not actually two phase. So we’ll get into the three phase power.

Where do you use three phase power? Um, typically commercial sites, industrial sites. If you’re a commercial facilities maintenance guy, um, you have probably seen three phase power in your building, but, uh, maybe you don’t know exactly what to do.

That’s where we come in as an a quality electrical contractor and we show you what’s going on with your system and, uh, what we can do with it, what you need to do with it, things to make it a more effective, more efficient. A lot of questions we get are, uh, why not more phases, four five, six phase power, 12 phase power.

We’ll get into that. Um, why that’s not really a thing. Um, and then we’ll kinda touch on the brief construction of a alternating current generator that might help you understand more about three phase power. And single phase power. Um, and then, yeah, this, uh, what exactly hertz really is, we’ve touched on that before in another video, but we’ll touch on it again.

So we’ll get right into it. So single phase power, that’s what you’re going to find in a residential application. So all of our residential electricians deal with single phase power every single day. Really single phase goes on and off so fast that the human eye cannot see it.

Single phase is great for lights, plugs, um, just about any device you’ll find in your house, even, you know, your microwave, your blender, uh, your washer, dryer, stove, it’s, it works great for all those things.

It’s less efficient for motors and that’s why you’ll get a higher current value on a single phase motor than maybe a three phase motor. So if that’s gonna come back to a Watts, and that’s how your power is measured by the utility company. But regardless, three phase power isn’t really effective in a home.

It’s not costly, uh, cost-effective because you need more wires and more copper. And that means more money. So for a commercial application or an industrial application, and that’s where three phase is really gonna come into effect more.
Especially if you have a pump that needs to move water. Well yeah, you can get a one 20 volt pump, but it’s not going to move near as much water as a three phase pump. You just, if you need that, if it’s going to be, if it’s going to be making you money, you need to move as much water as possible.

So that’s why you’re going to need three phase power for that. Same goes for a motor, right? You can have a single phase motor. Look at your bedroom fan, look at your fart fan in your bathroom, right? If you have a bathroom ventilation fan that’s operating on one 20 volt, that’s not two 40 volt and it’s working just fine.

But if you’re in an industrial situation or maybe you’re running a paint shop, you have an automotive shop, um, your electrician at your automotive shop or your car dealership or something like that. If, if, uh, he were to run one 20 all your fans, you wouldn’t get the suction that you need, um, to really suck those, those fumes out of there.

That’s why sometimes you want to have three phase power to those. The higher voltage, the more phases that’s going to give you a better power situation for if you have large pumps and motors.

Also lighting counter 347, 600 volt lighting, and that’s going to allow you to have a whole lot more lights on a circuit than a typical single circuits. So a single phase one 20 volt, that’s great. But you’re only going to get so much out of it.
So at the end of the day, you want three phase four large loads. That’s, that’s I guess what we get down to it. The larger the load, maybe you want three phase. So, uh, on a grand scale people say, Oh, why not more phases for phase five, phase six, phase. No, you’re not going to have any of that.

It’s costly and it’s not widely, widely accepted on like three phase a. The benefits of more phases are they’re inefficient and moot. It’s not applicable really. So if you were to have a three phase power, each one of those phases operates 120 degrees out of sync with E, with each of themselves.

So your first phase, it’s going to peak up and it’s going to peak down on a sine wave. So that sine wave simply reflects the speed of electrons that’s alternating backwards and forwards. So as the speed of electrons alternates backwards and forwards, plotting this on the graph gives you a sign wave pattern backwards and forwards, meaning up to the top of your sign wave and down to the bottom of your sign.

Wave sideways, just going to go up and down and up and down. And it’s going to repeat. So if you have one single phase, then when you’re up, you’re at your peak and when you’re down, you’re at your bottom peak and that’s where you’re actually getting your powering. That’s what’s giving you your light on.

It alternates so fast that the human eye can’t see it. So when you have single phase electrical power, your light is seeing that power go all the way up and it seemed at all the way down.

But the rest of the time it’s not really on right. So that’s, that’s why you’re seeing it, um, on all the times cause you’re, I just can’t register that. It’s actually flickering. If you were, if you were to go to, or gaming I should say, not flickering. If you were to go to a, a super slow motion camera, super slow motion that would be able to pick it up and you would see that the light is in fact not on 100% of the time to the full amount that it appears on.

Again, um, while we’re on the single-phase topic, we’ll get to two phase and why that’s incorrect. So it’s not actually two phase, says the Edmonton electrician. It’s a single phase. And when you are saying two phase a verse or imagining, you’re assuming one 20 volts difference to ground on one line incoming line to your home and one 20 volt difference to ground on the second line coming to your home cause you have two lines come into your home in one neutral.

You have those two lines coming in and that’s kind of power up. Not necessarily the left side of your paddle and not necessarily the right side of your panel, but it’s going to stagger. So line one is going to cover your top, your two top breakers. Line two is going to cover the next two breakers and so forth.

That way you can plug on any two 40 will break here. So when you say it’s a two 40 volt, uh, stove or a two 40 volt dryer, or even if you say two 20 volt, uh, essentially it’s two 40 volts. If you put a meter on it here in Canada, here in Edmonton. So as your Edmonton electrician, when we put a meter on it, um, we will show you it’s two 40 volt. It’s not two 20 or two 25 volts or anything like that.

That’s just a manufacturer spec wherever it’s coming from, if it’s coming from Europe or China or the States or wherever it’s coming from. But here in Edmonton, it’s 240 volts in your home, according to the Edmonton electrician. Again, it’s not 2 phase, we call it split phase. So it’s still single phase power 240 volt is still single phase power.

It’s just split phase. Cause when you have your transformer out, um, on the bucket, whether you have an overhead service, uh, pull ’em out to transformer or you have an underground service and the transformers out in a box out on the street, uh, regardless, that transformer is going to have their main primary lines coming in off of their utility three phase power.

So that’s going to come in and then branch off on one of those phases. You’re going to get one of those phases branching off to your transformer, um, and possibly at all your neighbors as well.

And that phase is going to go to a coil, which is going to step it down to one 240 volts that you see at your house. Now that coil is going to have on one side of the coil, one line coming to your meter, coming to your panel, coming to your line and your over your over current device and another line coming off the other side of that coil. So your coil is just a strata wire essentially off that transformer.

You can have 20 volt coming on one side, one 20 volt coming on the other side, and your neutral is to be right in the middle. So that’s why we call it split phase is because you’re getting one 20 volt difference to ground from one line to the neutral. And then on your other line to neutral, you’re getting another one 20 volt difference to ground.

And in that that a neutral line. When you get your two 40 volt, you’re actually getting the full range of that coil for your stove or your dryer or whatever other two, two 40 what would you have in your house? Maybe a hot tub, maybe an AC unit, um, w welder or whatever you have going on. But regardless, that’s why it’s not called to phase. It’s called split phase. Um, and again, why not more phases, four, five, six, et cetera.

Yes, costly, not widely accepted. Uh, but uh, when you have three phase power and each phase is 120 degrees out of sync, you’re going to have a small gap in between the tops and bottoms of those three phases where they’re not, um, fully where there’s going to be a gap. So if you added three more phases to fill those gaps, you’re effectively not filling the gap.

You’re just creating a smaller gap, but you’d have to run three more wires and have three more coils and that’s just going to get that much more costly. So, uh, again, if you were to add three phases every single time to not fill those gaps but make those gaps smaller, it’s effectively a half life situation, just like how radiation dies.

You’re never going to completely remove it, however you will make it smaller and smaller. But the amount of efficiency you would gain from filling up those small gaps with more phases, more coils, uh, and more cable, that’s not going to prove more efficient than your typical three-phase system. So that’s why we operate strictly in a three phase system. In Teslas, uh, Tesla experimented with two phase and, and with, uh, other amounts of phases, but the most widely accepted, the most widely used.

And uh, the most efficient systems are a single phase and three phase. So a three phase is going to come from your utility company, says your Edmonton electrician. It’s going to go to a step up transformer and shoot it across the neighborhoods that and commercial sites, et cetera. And then it’s going to branch off, uh, one phase for smaller areas and then it’s going to step it down further at another transformer for your home to work at a safe voltage cause you’re not going to have a 13, six, or 13, five KV.

Whatever the right value is, you’re not going to have that coming into your home cause that just would not be safe. Uh, so that’s why you don’t have more phases. That’s why two phase is not essentially a thing cause it’s not two phases. It’s really just one phase. And that’s why three phase is the most efficient way to have a high amounts of power current for a, your motors, your pumps, et cetera, your lighting, whatever load you may have in a commercial facility.

You’ll see three phase more often in industrial facilities. You’ll see it plenty there. But, uh, your commercial Edmonton electrician, we see it often for motors and pumps doing a lot of laboratory work here in Edmonton. We do a lot of electrical for laboratories and the motors, pumps, equipment lighting that they use is often three, phase three 47 volt, 600 volt.
That’s how that one works there. So you got to deal with a lot more hazard, a lot more shock when you deal with three-phase electrical. But at the end of the day, uh, it might be the right setup for your system. So as always, remember when you’re working with electrical power the hazards that come with it.

Injury, shock, death, property damage, those are all very valid, uh, hazards. They’re all very relevant to the trade. So if you are not qualified, if you’re not competent or confident in doing electrical work, you should call your local electrician.

Call Hauer power electrical. We are your Edmonton electrician. We serve all Edmonton, all of Edmonton and surrounding area. We’re happy to provide free estimates for all of our customers, new all existing. Uh, if you, if you think maybe we missed something in this video hearing you say, Hey, actually what about this? Uh, well, yeah, it’s a, it’s a wide topic. Search our page hauerpower.ca or search our YouTube channel and see maybe if we already made a video, cause if not, we’d love to hear about it.

And we’d love to make a new video and, and clear up any questions, concerns, or electrical issues, electrical topics that you might have, uh, and you might want discuss. So again, just to kind of summarize it all, your, your speed of electrons, that’s kind of alternate backwards and forwards. And if you plot that on a graph, it’s going to be a, what’s known as a sign wave pattern.

Those speed of electrons there, they’re cycling at 50 to 60 cycles per second. That’s what’s provided at your power sec station. And that’s what’s referred to as a your frequency of power, right? That’s your Hertz. Uh, here in Edmonton, um, our Edmonton electrician only see 60 Hertz.

You might see 50 Hertz in other places. Uh, you can put a 50 Hertz piece of equipment on 60 Hertz systems, but you cannot put a 6,000 system on a piece of equipment, sorry, on a 50 Hertz system, it just won’t work. He’ll burn out. Um, it’ll die faster. So as always here, as you’re heading into an electrician, our mission is to provide you with exceptional power and we do that through customer service.

And one more way that we like to reach out to our customers is through these YouTube videos. So if you like it, like the video, subscribe to the video. We make new videos all the time.
