Symmetrical Components

In this video, I explain how the method of symmetrical components is used to simplify asymmetrical three-phase voltages and currents. In the way of a thank you, for your interest, I’m making available:

In this video, I explain how the method of symmetrical components is used to simplify asymmetrical three-phase voltages and current analysis by converting the unbalanced system into three sets of balanced phasors and one of which is a set of single-phase phasors, or symmetrical components. These sets of phasors are called the positive, negative, and zero sequence components.
An understanding of Symmetrical Components is essential for the understanding of fault analysis and modern-day protection schemes. This video will provide you with the rudimentary knowledge to comprehend the concept and how it is applied

I don't think you realize how much of a life saver you are, appreciate it man.

[@everydaytolerate]

Thanks for wonderful lecture!!! This video makes me to understand symmetrical components completely!

[@barakatmo]

Thanks for the video. Studying for Power PE exam and this helps out a lot understanding the relationship between each phase.

[@tantanewyork1980]

Thank you! We appreciate it! great way to simple things! Well done! 👍👍👍

Thank you very much, excellent review for the PE electrical test

Brilliant explaination 👏

Thanks dear its helpful

Thank you sir! Very well 👌 explained the topic

Very very good explanation! Thanks for the video!!

Hi Graham, I like your lecture.Thanks

Hello...thank you for your interest in my TH-cam site. It was put together a while ago with an interest in reaching out to those interested in power systems. I have since expanded these as part of 14 courses related to electrical power and they are located on EEP - (Electrical Engineering Portal). My courses may be found by going to: academy.electrical-engineering-portal.com/courses...and selecting Graham Van Brunt P. Eng., B.Sc. after hovering over the "Authors" heading. The costs look expensive, but they are always heavily discounted. You will not be disappointed in any of them.

Great explanation.

thank you very much
I hope from you add the link of paper ❤️

at 32:05, the equations are messed up. ie, to work out the +ve seq comp, you need to rotate by 0, 120 and 240

[@pspt]

The equations are not messed up...each component has an A, B & C phase. The Positive sequence A, B & C phases are separated by 120 degrees as the Negative sequence A, B & C phases are separated by 120 degrees. The 0 sequence A, B & C phases are in phase with each other. The A phases of each component will vary relative to each other as do the B & C phases of each component.

Are you confirming if the 3 expressions on the left hand side of the screen are correct, refer timeline 32:05?

[@gadha707]

If you plug in the phasors into the expressions, you cannot possibly arrive at the results.
Your results are correct, but you have displayed the expressions incorrectly

[@JesusIsImmanuel]

@@pspt you are wrong and gadha707 is correct but not for the reason he is giving. your equations are wrong because they should be zero, positive, and negative sequence top to bottom and to the left of the equal sign not positive, negative and zero sequence top to bottom.

[@JesusIsImmanuel]

@@pspt compare with the equations on the right at 28:01

[@rodulfomolina5584]

Very intuitive explanations and very profesional. Can you just explain further on the start of 39:08, on how a to power negative2 become simply a, thanks.

[@prmax601]

From 16:40 u can see that a^(-1) = a^2, from this we understand that a^2=1/a hence while finding a^(-2) we substitute 1/a instead of a^2 in the equation a^(-2)=1/a^2 therefore we get a^(-2)=1/(1/a) which is nothing but 'a'

Love it

Can I get the ppt presentation file please?
