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.
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!
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!
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 !!! 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.
"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.
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.
ok ok, i watched this video 4 years ago and really like this drive harmonics video... however, what new drives are there in 2020, not needing reactors and the like? thanks...:)

Hands down the best explanation of harmonics on the internet for all electrical disciplines & skill levels. Thanks Steve & Yaskawa!
Xoxo 😘

such a professional presenter is highly required nowadays.
Thank you, sir, this was so informative and compact.
Steve must be one of the best instructers ever. No sleeping in his class.
One of the best videos on CZcams ever. Period!

"AFE uses IGBT to reduce THD in VFD, OMG!!" : Loved the part
Thank you, Training Manager, @ Yaskawa for teaching complex subject in simple language
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!
OMG... Give that man a raise!
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.
Wonderfully presented! Thank you Steve and Yaskawa!
Wow. I’ve searched so long for an explanation like this.
Thank you.
A lot better lecture than my top university professor
Listening to this with an epic musical score in the background makes it so much cooler.
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?
What a magnificent description and presentation. Thank you.
Thanks for the training video and clarification of sound travel and electricity. Very informative.
Mr. Steeve your style of teaching is very excellent
Best explanation on harmonics i have ever come across...amazing work
thank you very much for the great presentation.
Complete and ideas flow very well. Thank you Yaskawa.
Oscar for this guy plz
Best lecture ever
OMG
Agreed
I have seen 18 pulse drives in the mining industry where motors go up to or more than 33MW. Great lecture
Great video, thanks for the upload.
Best Harmonics explanation for beginner !!!!! on internet world
Omg wat an amazing explanation., best CZcams award goes to this ☝️
Goat content. Fantastic. Very much appreciated sir!
Thank you for this video.Great explanation hope we will get more videos like that.
You are the best tutor in the world.
Excellent presentation! Well done, with great visuals!
Excellent trainer. Thanks a lot mate
Best Explanation and clearly mentioned all points....👏👏👏👏
Thanks for making this video. I found it very helpful!!
You're are a great lecturer.... Thanks yaskawa
great comprehensive presentation !!
Excelente informacion, todo queda bastante claro.... thanks!
Thank you... Perfect explications.... From Algeria...

Very clear and easy to follow, great presentation style - well worth the watch (and re watch).
Thank you Sir for your explanation about the harmonic problem in the network power system
Best teacher I ever seen
Wonderfully presented!
best explanation for harmonics.thankyou
amazing explanation skills.... thanks a ton for your class
Very good lecture
Thank you

a very good brief on harmonics
Thanks for that. This is something very interesting.
Wonderful lecture!
Thanks a lot.. this reminds me the old school!!!

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