If you have landed on this page, you have shown at least a passing interest in short circuit analysis. This course is intended to provide the fundamentals of short circuit analysis. It is not the be all and the end all and you could go on for hours and hours and days and days and days in the way of courses and courses that could touch on the subject matter involved in short circuit analysis. However, this will provide the basic understanding of what goes into short circuit analysis and with manufacturers are intending for you as a protection engineer or technologist to understand their product when it meets the real world. So I'm going to in the next few slides introduce the fundamentals of short circuit analysis. What is this course?

And you can see for yourself? Are these the type of things that you will want to have? And if the answer's yes, then here they are. In this course, we are going to be dealing with high voltage systems. And fundamentally, we're going to be looking at short circuit analysis. And we're going to be covering phase two Ground Type faults, phase two phase short circuit faults.

We're going to be looking at phase two phase, two ground short circuit faults. And we're going to look at three phase short circuit faults. One of the things that we're going to be doing along the way to the process of analyzing these types of faults is we're going to be looking at some tools in order to do that. And one of the basic tools that all power engineers use his per phase analysis, which fundamentally is taking three phase system and reducing it to a single phase system so that the analysis can happen easily. Now this has to be taken place in a way of a balanced system. And we're going to talk about that in the, in this course.

And we'll see how we can use per phase analysis to our benefit, and be able to then extrapolate backwards in order to get the quantities we want and in the three phase values. Another tool that we will be using is the per unit analysis and the normalization process of a system. Now, there is another course in pspp Academy that deals with this subject better in a lot more detail. And it has a lot of examples that you work out so she can get to be very good at doing per unit analysis. However, there's a quick review in this course to make sure everybody's up to speed and can Use the actual per unit systems which is basically the understanding of what a per unit system is and how it works with transformers. Primarily the most important thing is it gets rid of the turns ratio in a transformer when you're analyzing the system.

And it also gives you an understanding or at least in this course, we will develop an understanding as to whether or not there will be a phase shift as you move from the primary to the secondary of a three phase transformer. And we will deal with that during this course as well. One of the most powerful tools developed for the use of system analysis under fault conditions is symmetrical components. And symmetrical components essentially takes a symmetrical quality And converts them to the summation of three symmetrical components. Once you're dealing with symmetrical components, we can now use our simplistic forms of analyzing us three phase system. And that is we can do it using per phase analysis, and or using per unit analysis with it as well.

So this is a very powerful tool, and we're going to see how this works. We're not going to develop the proof for it, but we're going to use the results of it. And we're going to be able to look at developing formulas for converting asymmetrical phasor quantities into symmetrical components. And then we're going to be able to look at converting those symmetrical components back over to asymmetrical quantities. Once we've done the analysis. We're then going to look at a symmetrical three phase fault conditions, the ones essentially we mentioned At the beginning of this narrative, and going along that path, we're going to develop a positive network system, a negative sequence system and a zero sequence system.

And then we're going to see how the particular types of fault configurations will align these three networks together, and we'll be able to analyze the system using these types of circuits and and and the fallouts from them. We're then going to do some system modeling, which involves the major components of a three phase system that in other words, the transmission lines are feeders, the synchronous machines, and the transformers. And we're going to look at specifically how the transformer configurations have to be dealt with when looking at your zero sequence component. It's in the various transformer configurations. So the course is about three and a half to four hours long. I've divided it up into chapters so that you can take it one step at a time if you'd like.

And the Academy is set up in such a way that you can interrupt your training at any time and pick it up at a later time at your convenience, so move forward, click on the the purchase button, and I hope you enjoy it. There's room for comments at the end. And if you have any questions, you can put those in there as well. And I'll endeavor to ask or answer them as fast as I possibly can. So take the course and enjoy it.
