All electrical engineers of the world should get together and pay this gentleman a million dollars a month to explain every topic of every course needed for a master's degree. Then, we could retire all other living professors, starting from my lazy professors.
Hands down the best explanation of harmonics on the internet for all electrical disciplines & skill levels. Thanks Steve & Yaskawa!
Xoxo 😘
Actor-standard/president-standard speech delivery!
+ direct, concise, clearly-explained contents. Cannot be marked. This exceeds expectation!
(Ps The presenter is not bad as well - handsome, calm and man with a kind-looking personality. well done!).
Steve must be one of the best instructers ever. No sleeping in his class.
Man, speaking as a person from a non-english speaking country, I must congratulate you for the very paused and clear pronunciation of the words. Beyond that, the high value content and the masterful way in which the subject was explained! Congrats!
"AFE uses IGBT to reduce THD in VFD, OMG!!" : Loved the part
One of the best videos on UA-cam ever. Period!
such a professional presenter is highly required nowadays.
Thank you, sir, this was so informative and compact.
Excellent tutorial! Very clear, concise, and precise. I wish more engineers would talk like this :)
Thank you, Training Manager, @ Yaskawa for teaching complex subject in simple language
yaskawa is very sincere manufacturer , even in eighties i have seen a yaskawa motor which did not require any regular maintenance at that time compared to other brands . liquid starter never gave trouble for 8 years in a row , and was free from dust in our heavy dusty environment @ a cement plant .
I am working in ABB as drives quotation specialist but believe me I have not come across such detailed explanations on THD/TDD and mitigation options... hats off to you sir!
@Zaheer Ahmed Sir are you from ABB Bangalore?
Excellent presentation with a clear voice for non-native English speakers....Thank you!
OMG! Best explanation on power distortion!!!!! So simple, yet so elegant! Thank you so much for the upload!
Thank you for your insight. I have been forwarding the video to clients so that they can understand what they pay for.
What a magnificent description and presentation. Thank you.
OMG... Give that man a raise!
Listening to this with an epic musical score in the background makes it so much cooler.
Wonderfully presented! Thank you Steve and Yaskawa!
I have seen 18 pulse drives in the mining industry where motors go up to or more than 33MW. Great lecture
Thanks for the training video and clarification of sound travel and electricity. Very informative.
Mr. Steeve your style of teaching is very excellent
Complete and ideas flow very well. Thank you Yaskawa.
Wow. I’ve searched so long for an explanation like this.
Thank you.
Best explanation on harmonics i have ever come across...amazing work
Oscar for this guy plz
Best lecture ever
OMG
Agreed
A lot better lecture than my top university professor
You are the best tutor in the world.
Best Harmonics explanation for beginner !!!!! on internet world
Very clear and easy to follow, great presentation style - well worth the watch (and re watch).
Best Explanation and clearly mentioned all points....👏👏👏👏
thank you very much for the great presentation.
OMG !!! after a long time struggling and searching, this is the only video that answered my question and gave good understanding of it. Million thanks to him. So, nice lecture (but not really the way of traditional lecture though). Once again thanks a lot.
This explanation was so beautifull that I lerned something about harminics mitigation in large power generators. And i was looking for harmonic distortion in audio amplifiers. Great work indeed. Really interesting. Thanks.
Omg wat an amazing explanation., best UA-cam award goes to this ☝️
Excellent presentation! Well done, with great visuals!
Thank you Sir for your explanation about the harmonic problem in the network power system
Best teacher I ever seen
Thank you for this video.Great explanation hope we will get more videos like that.
Excellent trainer. Thanks a lot mate
Great video, thanks for the upload.
Excelente informacion, todo queda bastante claro.... thanks!
Very nice and beautiful explanation to understand and to mitigate Harmonics. Thank you Sir,we expect more such analysis.,🙏
a very good brief on harmonics
great comprehensive presentation !!
These educational videos are a great overview, thanks.
We are glad that you think so!
Excellent presenter and the material covers all
You're are a great lecturer.... Thanks yaskawa
Thanks for very clear, fluent and efficient explanation for Harmonics.
A well done work is timeless. 9 year old instructional video and still awesome! The TDD table meant for point of common coupling was indeed used by PQ specialists within load side facilities because they give a good reference point. You just need to be aware of how you interpret the results.
Nice and clear with proper reference
Good and clear vision on Harmonics very useful
Goat content. Fantastic. Very much appreciated sir!
Wonderfully presented!
Thanks for making this video. I found it very helpful!!
Thank you... Perfect explications.... From Algeria...
best explanation for harmonics.thankyou
Very good information. Keep the videos coming.
Thank you, sir. Very good video!
"What kinds of harmonics do variable speed drives create? Well, it depends." Now that is definitive for you! How's about this: Just like with other loads, variable speed drives distort the input wave causing harmonics. The ANGLE that the input wave was at when it impacted the distortion determines which harmonics are created and the pattern of harmonics created in the spectrum. This pattern is known as the Harmonic Signature, and the Bullard Harmonic Solution can be used to predict the harmonic signature based only on the angle that the incoming sinusoid was at when it impacted the distortion. This is Law #2 of the Bullard Laws of Harmonics. Different devices (VFD, fluorescent lights, rectifiers, etc) have distortions lurking at various voltage thresholds and when the incoming wave impacts those thresholds, it distorts the wave and the angle at which that happens determines the harmonic signature. God did not anticipate which electronic devices mankind might invent and then devise a set of harmonics for each and every human invention.
Excellent lecture . Thank you
Best explained #PowerLearningChannel
Thanks a lot.. this reminds me the old school!!!
amazing explanation skills.... thanks a ton for your class
as the lecture for the inductive motors, this one is as well very good. congrats:)
Brilliant video!
Good presentation on harmonics.
Very good lecture

That was great!
excellent explanation
Informative lecture
Loved it ❤️
Amazing lecture
It's very Informative
Muito boa a apresentação.
Learn a lot...Thanks sir
Such a phenomenal video. I have more questions now than when I started the video, but that's because the topic was covered so well, that it made me realize how much more I need to know about Harmonics, IGBT's, EMI Filters, etc. I am particularly interested in how the drive provides regeneration @ 21:30 Thanks so much for providing us with such great instructional videos.
Thanks for your interest! Additional support and training options are available. Learn more: www.yaskawa.com/support-training
Pete vree you doing same thing this gentleman doing I mean teaching us science because of that thank you and keep going please
Im using this video to help with drum and bass production and i actual understand what he’s saying haha
very good presentation
I am become a fan of this gentleman
Nicely done
Amazing explanation sir
excellent!!
Sir continue to electrical lecturer Ur teaching in excellent and better life students
Bro you didn't get it??? It's an advertisement of yaskawa. They are provided their own solution to mitigate harmonics generated by VFD
good explanation.
