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!

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!).

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!

One of the best videos on KZfaq ever. Period!

"AFE uses IGBT to reduce THD in VFD, OMG!!" : Loved the part

such a professional presenter is highly required nowadays. Thank you, sir, this was so informative and compact.

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!

Excellent tutorial! Very clear, concise, and precise. I wish more engineers would talk like this :)

Excellent presentation with a clear voice for non-native English speakers....Thank you!

Steve must be one of the best instructers ever. No sleeping in his class.

Thank you, Training Manager, @ Yaskawa for teaching complex subject in simple language

OMG... Give that man a raise!

OMG! Best explanation on power distortion!!!!! So simple, yet so elegant! Thank you so much for the upload!

What a magnificent description and presentation. Thank you.

Thank you for your insight. I have been forwarding the video to clients so that they can understand what they pay for.

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 .

Best Harmonics explanation for beginner !!!!! on internet world

A lot better lecture than my top university professor

I have seen 18 pulse drives in the mining industry where motors go up to or more than 33MW. Great lecture

You are the best tutor in the world.

Best explained #PowerLearningChannel

Best teacher I ever seen

Best Explanation and clearly mentioned all points....👏👏👏👏

Listening to this with an epic musical score in the background makes it so much cooler.

Wonderfully presented! Thank you Steve and Yaskawa!

Oscar for this guy plz

Mr. Steeve your style of teaching is very excellent

Wonderfully presented!

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.

Omg wat an amazing explanation., best KZfaq award goes to this ☝️

Best explanation on harmonics i have ever come across...amazing work

a very good brief on harmonics

These educational videos are a great overview, thanks.

Thanks for the training video and clarification of sound travel and electricity. Very informative.

Wow. I’ve searched so long for an explanation like this. Thank you.

Goat content. Fantastic. Very much appreciated sir!

thank you very much for the great presentation.

You're are a great lecturer.... Thanks yaskawa

Complete and ideas flow very well. Thank you Yaskawa.

Hi, I like your lecture

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.

Excellent presentation! Well done, with great visuals!

Excellent lecture for basic understanding

Very good lecture Thank you

"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.

Thank you Sir for your explanation about the harmonic problem in the network power system

Great video, thanks for the upload.

Thank you for this video.Great explanation hope we will get more videos like that.

Thank you... Perfect explications.... From Algeria...

Very nice and beautiful explanation to understand and to mitigate Harmonics. Thank you Sir,we expect more such analysis.,🙏

Excellent trainer. Thanks a lot mate

great comprehensive presentation !!

Excelente informacion, todo queda bastante claro.... thanks!

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.

Brilliant video!

Thanks for making this video. I found it very helpful!!

Unquestionably excellent quality. In India, any job possibility. Grateful to join yaskawa. Kudos

amazing explanation skills.... thanks a ton for your class

Good and clear vision on Harmonics very useful

Very clear and easy to follow, great presentation style - well worth the watch (and re watch).

Thanks a lot.. this reminds me the old school!!!

best explanation for harmonics.thankyou

Excellent presenter and the material covers all

Nice and clear with proper reference

Wonderful lecture!

Excellent steady explanation sir Thank You

Very good information. Keep the videos coming.

Excellent lecture . Thank you

Best representation ever!!!

Thank you, sir. Very good video!

Good presentation on harmonics.

Very good explanation!

as the lecture for the inductive motors, this one is as well very good. congrats:)

Excellent information , well done YEA

Loved it ❤️

Very use full ..... Thank you..........

fantastic way to explain the invisible giant ................

Thanks for that. This is something very interesting.

Amazing lecture

the good information for me! thanks

Thanks for very clear, fluent and efficient explanation for Harmonics.

Thanks from #PowerLearningChannel

Excellent explanation.

I appreciate this is the lesson about harmonic....

Excellent

That was great!

It's very Informative

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.

The best harmonic explainantion❤

Informative lecture

Learn a lot...Thanks sir

he is a genius !!

Muito boa a apresentação.

Sir continue to electrical lecturer Ur teaching in excellent and better life students

Amazing explanation sir

Nicely done

I am become a fan of this gentleman
