Presenter:: Hi, this is an introductory video on how easy it is to use EasyPower for creating one line diagrams, automated design, short circuit, protective device coordination, and arc flash hazard analysis. We're going to start off creating a one line diagram with simple mouse clicks. I'm gonna left mouse click on this utility, left mouse click again in the drawing area. you can see it snaps to grid. I'm gonna grab a conductor, we'll left mouse click. Drag and release. We'll say [00:00:30] that this is a 13.8 KV conductor in this wizard and then it snaps in a connection point or a bus.

What we'll do now is grab a transformer, 2 winding transformer left mouse click, snaps in the high voltage bushing terminals to the transformer and then on the secondary side we'll put the low voltage bus way. We'll make that 480 volts. Say "okay", that snaps in the secondary low bushing voltage terminals. [00:01:00] The bus way into the switchgear lineup. So we'll grab a low voltage switch gear lineup. We'll make that with a main, 480 volts, low voltage power circuit breakers. We'll say 3 motor control centers, connected with conductors down to MCC's and that creates that for us. Then we'll just left mouse click, snap that together. There in 6 or 7 mouse clicks is a typical unit substation that you would find in any industrial [00:01:30] or commercial type facility.

What we want to do now is add some load to the motor control centers and then we'll do is allow smart design completely automate the design process by sizing all the equipment for per NEC code requirements. So I'm gonna left mouse double click on this motor control center, I'm gonna go to the description tab, tell it that I have 2 buckets, and you can have as many buckets as you choose, but in order for this demo we're going to keep it small. I'm going to make the [00:02:00] first group less than 50 horsepower motor group, and then we'll have a motor with a time current curve.

Now, I'm gonna click on this motor spec tab, I'm going to slide the cells over and I'm gonna put say, 150 horsepower of group motor, low voltage motors, and then I'm gonna click on this data button for the larger specific motor with a time current curve and I'm gonna say this is a 200 horsepower unit. [00:02:30] 240 full load amps, short circuit, ANSI code greater than 50, X/R ratio of 12, and then I'm going to slide over to the protective device starter information and I'm going to size the conductors and the breakers for this 200 horsepower motor. So, I'm gonna right mouse click, auto size, tells me the row was successfully sized with a mag break, GE mag break TJC 400 amp interrupting 30 Kilo Amps [00:03:00] and now we're good to go.

Also notice if we slide this over we can see that the conductor was sized, the conduit run and that type of thing. So what we'll do now is select "Okay". Now what I'm gonna do is in the essence of speed I'm gonna copy this to the other MCC, so I'm gonna right mouse click, copy, left mouse click, press slide release, right mouse click, paste, and now that information [00:03:30] is in the other motor control centers. Now that we have the MCC's load documented what I'm gonna do is come up and grab a high voltage breaker for this feed, and there are some other features that we have.

Let's go to insert subsystem, I'm gonna grab a basler 851 relay system. I'm gonna highlight that and drag it over and snap it in. So there's the 851 relay system. [00:04:00] Now we're ready to size our equipment. So what we'll do is highlight this, right mouse click, and will go auto design, and you can see that our equipment, all are conductors, and our transformer are all sized. Now we're ready to go analyze the power system. First thing we want to do when we analyze the power system is we'll go to short circuit focus. You can see that the ribbon changes [00:04:30] when we get into short circuit focus. Now' I'm gonna hit "fault all the buses", this is like a batch fault. When I select that all the different buses are faulted and you can see here's 26 kilo amps, 20 kilo amps from the transformer and about 1900 amps from the motor control centers.

Now, we can look at different options such as interrupting and 30 cycle fault currents, we [00:05:00] can look at arc flash, we can hit equipment duty, except that we automatically, we sized this with smart design so everything's sized correctly so we won't see a lot of information there. So, the next thing we wanted to look at is protective device coordination. So I'm gonna click on this little focus button. What I'm going to do then is just highlight this section, I'm gonna hit "Plot TCC", [00:05:30] and over on the left hand side is the one line that we're analyzing. If I hit the faulted bus currents you can see all the short circuit currents on, from the MCC's and everything. Now, this is a system-wide total current. I'm gonna get rid of the title block so you can see this a little bigger.

Now what I'm gonna do is press smart PDC. This the world's first automated protective device coordination program, Now you can see that the system is not selectively coordinated. [00:06:00] When I click on this button it's going to selectively coordinate everything and I'll just drag these tool tips over here and we can actually zoom in and see the coordination. So you can see everything's correct. We can actually click on different devices, right mouse click and say "insert difference calculators" and you can actually see the protective device coordination and we can slide these up and down [00:06:30] or across and get all the information that we need. Now, another thing we like to look at when we're in protective device coordination is what's actually happening to the arc flash hazard. Now you can see when I go and press this little arc flash button what the arc flash based on our current settings are going to be.

So you can see down at the motor control center we've got 8.4 calories, #3 PPE, up on [00:07:00] the main breaker, incoming breaker is 79 calories and then that breaker then is protecting the bus 4 switch gear lineup at 15.9 calories. So you can see with just a couple mouse clicks we can analyze just about anything there is to see. Now can make adjustments and that will change the arc flash hazard values. Let's go back to short circuit focus. I'm gonna click out of here, we're not gonna save this information. [00:07:30] If we go and press our, fault all the buses based on short circuit focus, you can see here are our values for the different parts of the system. If we go to our arc flash hazard report we can say, okay, let's go get a report. You can see all of our different values, [00:08:00] what's at extreme danger. The pink shows that the 85% rule was used and then we can just click on a particular item and we can view our arc flash hazard label.

So you can see this gives you a really quick and easy way to create your one line, get all your arc flash hazard results, your protective device coordination, and your short circuit results. There's many other features in EasyPower including dynamic stability, [00:08:30] transit motor starting, harmonics, power flow, elevation schedules, multiple drawings, but this gives you a quick overview. Thanks for taking the time and looking at EasyPower. [00:08:50]
