It always made me wonder whenever I would look at line voltage with a oscope and see a crappy looking "sine wave". Now I have more of a clue. Thank you.
Thank you very much for your lecture. Im studying electrical engineering and i have learned about harmonycs in my university only 1% of all this you explained. Better to study on the you tube rather to go in school !
Sir greeting for da day, I know u are a busy man but I am asking is der any easy way to learn capability curve of a synchrons generator..... Plz reply ASAP
The best source of information on and performance curves for synchronous generators is the data sheet from the manufacture of the generators themselves.
@@joeschmidt6597 Which harmonics are created is not a function of the kind of circuit you are using. 6 pulse rectifier vs 18 pulse rectifiers don't create specific harmonics just because they are have a certain circuit topography. There are laws that determine which harmonics are created and it's based on the angle at which the incoming sine wave was at when it intercepted the non-linearity. Read my book, don't wait for the movie.
@@englandrasmussen3111 The PHASE ANGLE where the distortion impacts the input sine wave determines the "Harmonic Signature." It has nothing to do with anything else. Not only did I discover this, I came up with the formula that predicts why you get the 5th, the 7th and the 11th. The phase angle where the distortion hits the sine wave is what drives it. I found a mechanical website that showed a harmonic signature from a galled bearing and laughed my butt off as I read the idiotic excuses for this harmonic signature. I poked fun at them and got in trouble with the sys-admin for that site, so I made this video explaining how that works. ruclips.net/video/17PtfpLDV44/видео.html
QUOTE "Single largest cause of severe harmonic distortion is resonance" UNQUOTE. Not exactly so - though the harmonic resonance does cause some severe harmonic distortions. If one applies only Capacitor with a Non-Linear load, the capacitor would magnify harmonics and one would land into a severe harmonic situation. Save for that, it the extent of Non-Linear Loads and when the transformer operates near its full capacity (with high VFD drives etc.) that cause THE REAL AND THE SEVERE HARMONIC DISTORTIONS, both with the THDi (Total current Harmonic Distortion) and THDv (Total voltage Harmonic Distortion).

Really nice job, materials were expalined so deliberately
.
Thank you very much for your lecture.

you need to study and learn on your own. don't rely to your professors mate.
Really well explained! Loved the information.
What happens to third harmonics if you use line to line voltage supply instead of line to neutral?
great presentation
Can I get the file of the presentation? Thank you
If single phase loads are connected line to line, where will third harmonics flow
Thanks, very informative.
Can I get the presentation
Are they giving a copy?
These harmonics makes the power meter charge you more for electricity because of how the meter works. How can this be corrected?
Eliminate the harmonics

Excellent
Very interesting
Good job
thank you loved person
Hi, I like your lecture
good
shuduk item
Nope. Not even close.
What you mean?

Tell me why I see 5th 7th and 11th harmonics on my supply with 6 pulse vfd loads than . 😂 gtfo here this info is spot on
