Okay so now I've looked through every video in this playlist except for the last one. Not only is this by far the best explanation of this specific subject there is, it's also one of the best instructional videos I've ever seen in any category. I'm having a test in roughly 2 weeks and when I got the symmetrical components part in the book it was like running into a wall. Super hard to understand. Can't praise these videos enough, excellent tempo, the music is quiet enough to not distract from the voice and you even added timestamps in this video. Thank you so much!
In Power System Protection course we will cover the requirements needed to design protective devices and the applications of these devices through a schematic diagram. Furthermore, this course will analyze the effects of all types of faults in power system along with the easy hand on calculations. To develop your strong concept on fault analysis we will discuss how faults can be identified by analyzing waveforms. Lastly, you will learn the most tedious and complex theory of symmetrical components that are found in different types of faults. This module consists of six parts, each building upon your knowledge based on previous ones. Currently, we are offering 90% discount, join us before it ends: bit.ly/Power-System-Protection
Hey you guys, thanks for the feedback. For all our upcoming videos we won't add any music. Unfortunately, UA-cam doesn't allow us to remove the music from previously uploaded videos. Thank you for your understanding. -GeneralPAC team

About the section around 4:53, just want to point out that a 3x3 matrix multiplied by another 3x3 matrix should result in a 3x3 matrix, which in this case would be a 3x3 matrix full of 1's. And thanks for all your videos, I appreciate the clarity and visualizations. EDIT: As pointed out below, I must have meant a 3x3 matrix with a diagonal of one's (identity matrix).
Great to hear! We just launched our "Power Systems Engineering Vlog" series. In PSE Vlog, we will discuss all of the various power system engineering studies & AllumiaX's blog commentary. We hope you'll join us in this series and benefit from it. Signup now: bit.ly/33dB0MM
Great work. May you live a long life Full of gladness and health . May all God's blessings descend upon you. May peace be within you. May your heart be strong. May you find what you're seeking wherever you roam.
In an earlier video it was explicitly mentioned that in a^2 and a^3, 2 and 3 are not powers but superscripts. Just a little annoying but I am enjoying the series. thanks so much. this is pretty much what varsity is now XD
Hi Waka, The earlier video you are referencing is "Principles of Symmetrical Components Part 3". When we say that a^2 and a^3 are only superscripts and not squares, we are just intending to steer clear of any confusions this method may cause, for example, some people may mix this with the transformer ratio, which is also denoted by a, and its square is a very important part of per-unit systems. Studying power systems is, undoubtedly, very confusing to begin with and our mission is to make it easy to understand, so that the knowledge can reach further. We are delighted that you're enjoying the series and finding it helpful.

The whole playlist is very informative. Just got confused and cannot really understand part 3:23 to 3:43 of this video. Can anybody explain please. Thanks in advance.
Hey Mary, in this part the A inverse of the matrix is expressed. It is being calculated and its value is directly shown in the video. Best regards, GeneralPAC by AllumiaX
Instead of multiplying Inverse A matrix in the final result ,it is multiplied with A matrix .Another thing you have not derived Inverse A matrix at 9:52 .You have proved it thru back calculation
Thanks for the very useful videos. It help me understand the math part. But one thing is incorrect: A matrix (3by3) multiplied by A inverse matrix (3by3) should result in identity matrix (3by3).
Yes! You can normally find a writeup on the tutorial here: generalpac.com/symmetrical-components/principles-of-symmetrical-components-part-1 however, much of the tutorials need to be updated accordingly.
Hi Matt, Yes you are right. But it was just to explain that what will be the product of operator a and a^2. Also to verify the inverse A matrix. If you solve it in the 3x3 matrix multiplying rule the output will still be a 3x3 identity matrix. Hope you find it useful. Thanks, GeneralPAC by AllumiaX
Thanks very much, but I've 2 comments: 3x3 matrix multiply by 3x3 matrix = 3x3 matrix not 1x1. And the last inverse A matrix you replaced a and squared a.

thanku so much for this video, but at the end there is a mistake u have rewritten the Matrix A instead of the A-1

I wish u were there 12 years ago when i was an undergrad. ur 1 hr tutorial is 1000x better than a whole year of my professors class

Congratulations on a fine set of videos! (There are very occasional errors but its good to feel confident enough to be able to identify them.)
But sir, around 9:13, the final matrix form that you have written,, has 'a', been misplaced.. within the 'A' matrix.
Dear, Thank you for this great tutorial. Last matrix have a mistake a & a2 are swapped since it is A-1 matrix
About the section around 4:53,
just want to point out that a 3x3 matrix multiplied by another 3x3 matrix should result in a 3x3 matrix, which in this case would be a 3x3 matrix full of 1's.
And thanks for all your videos, I appreciate the clarity and visualizations.
EDIT: As pointed out below, I must have meant a 3x3 matrix with a diagonal of one's (identity matrix).
Right, I've updated the comment to prevent possible confusion.
Aww yes... Thank you for the clarification Peter & Ricardo! Hope this video was helpful :)
Identity matrix, the diagonal is 1, others are 0
seems like the last format of the inverse of A at 9:46 is wrong as second and third columns are reversed. Overall speaking, you do a good job.
thank you very much, this set of lessons saved my life!! working with ieee 37 node feeder and this was fundamental for me to model it!

Thank you very much from Malaysia.
perfekt. thanks from Germany
What a great tutorial it is!!!!!!!!!
@ 9:24 ISNT THE A OPERATORS NOT INTHIER RIGHTFUL PLACES????
all your video's and explainations are excellent. Thanks to you. Can you explain how to obtain sequence components from the unsymmetrical components.
The whole playlist is very informative. Just got confused and cannot really understand part 3:23 to 3:43 of this video. Can anybody explain please. Thanks in advance.

Can you show please show the solution how you were able to get the determinants at 3. thanks

Where did the 1/3 come from, bro?
Do you offer write up of these turtorials and if you yes how to acceed?
Yes! You can normally find a writeup on the tutorial here: generalpac.com/symmetrical-components/principles-of-symmetrical-components-part-1
however, much of the tutorials need to be updated accordingly.
Thank you so much
Isn't a 3x3 multiplied by a 3x3 = 3x3 matrix? How do we get a 3x1?
Hi Matt, Yes you are right. But it was just to explain that what will be the product of operator a and a^2. Also to verify the inverse A matrix. If you solve it in the 3x3 matrix multiplying rule the output will still be a 3x3 identity matrix.
Hope you find it useful.

There's an error in the A^-1 matrix in the last
good!!!
As per your explanation at 8.59 . You entered A in the place of A-1
Salam , I have the video but i can,t understand
Thanks very much, but I've 2 comments: 3x3 matrix multiply by 3x3 matrix = 3x3 matrix not 1x1. And the last inverse A matrix you replaced a and squared a.
Wrong inverse matrix
Great lesson, but STOP calling "a" superscript 2 for a^2. It becomes confusing! The conclusion is actually A*A^-1=1.
Thank you Stephen for bringing this to our attention. This is a voice over issue. Our support team is working to have it fixed.
