PHASOR 10 - A basic Power System

[@alinurcaglayan9694]

thank you sir, phasor series was perfect. from 1, to 10. greetings from a student of electrical and electronics enginnering in turkey!

[@nkochurov]

Thank you so much for doing this. I'm currently in a power systems class and this taught me more than my teacher over a course of a week.

[@foghorn51rater]

I am extremely sad that I've jsut found your videos now that im studdying for my final in Circuits. You are very clear, have a fun accent, and clearly have a deep understanding of what you are talking about. Thank you very much for this sereis of videos, its been very helpful, and I hope I have trouble with another topic on which you have a series on so I can watch more.

[@rolinychupetin]

Thank you, both Mr. Carrico and Mr. Hashioka, for your comments and, very important to me, for including the country from where you are posting. Both Brazil and Portugal are among my favourite destinations when I'm abroad.

[@JonasFilipe9]

Better than classes I had at the University! Just great, Thank you. Greetings from Portugal!

[@الودطبعي-ر2ط]

Thanks alot sir >>from saudi arabia .. By the way . I realy like your interesting accent Gratefully..

[@rolinychupetin]

You are most welcome. And thank you for including your country in your post. Sincerely.

[@Ostebugle]

Thank you very much, my teachers complicated this topic way more than it had to be

[@rolinychupetin]

Glad it helped!

[@ahmadhamidbayat3754]

You are awesome, I wish in France the professor could be like you.

[@rolinychupetin]

You are really enthusiastic. I am sure there are. You just have to run the odds of finding one. The connection teacher-student is similar to the one between patient and doctor. It depends on so many apparently insignificant parameters. The Internet just makes it more likely to find the one that suits you. I am sure that my style may not suit everybody, but it does suit you. Many thanks for your enthusiasm, praise, and support.

[@rolinychupetin]

Thank you, Mr. Caglayan, for taking the time to submit your feetback. And also, for letting me know from which country. I mention to my colleagues and students a post like this of yours: "... today, a student from Turkey, Mr.Caglayan, posted a kind note on one of the KZbin videos ...". Thank you.

[@Miguelgarcia888]

this is all making sense now. thank you so much for doing these videos.

[@viniciusmunhozmartello1220]

Thanks from Brazil!! Way better than my teacher

[@rolinychupetin]

+Vinicius Munhoz Martello Thank you kindly, Mr. Martello. I have had some Brazilian exchange students in my classroom over the years and I have learned from them to say: Obrigado!

[@PepperDeVillle]

Thank you from Wisconsin, USA. This really helped clarify things for me.

[@rolinychupetin]

Thank you for commenting and for including your location. Nice to year from you M. Thelonia from Wisconsin, USA. I'm glad to be of help.

[@furqanimran1146]

Thank you Sir... The way you explain things is amazing!!!

[@suratkhan2208]

Thanks, Excellent Explanation, Great Teacher. Thanks from Pakistan

[@w18kev]

Hi, Great video. Where can I find the answers and worked examples to the exercises at the end?

[@fayrouzghaly2758]

your voice made me wanna study more , thank you from Egypt :)

[@winnyletiyo611]

Your the best.and u really save my life with this video,am taking Electrical machine course 😊

[@RanitSikdar]

thank you very much for this excellent video sir...from India with respect :)

[@lz1688]

Thanks from India and UAE.

[@Jessie-ye7fh]

awesome. Thanks from Australia.

[@franciscoalvarez5215]

Thank you, sir. From Venezuela.

[@rolinychupetin]

Gracias por tomarse el tiempo de incluir sus comentarios. Senor Alvarez de Venezuela.

[@inceptionpart2888]

Thank you/gracias desde Honduras.

[@rolinychupetin]

You are welcome. Thanks for reporting the country that you write from. Best wishes from Canada.

[@mohammedalqayodhi3684]

Thank you, from "Sultanate of Oman"!!

[@rolinychupetin]

Mr. Mo, thank you for reporting your location. Greetings from Vancouver, Canada.

[@kolmohmed]

Thank you sir , all the way from Malaysia

[@rolinychupetin]

+kolmohmed Thank you for posting, Mr. Kolmohmed from Malaysia, and even more for including the country that you are writing from. Sincerely.

[@davidepavanello4624]

Thank you, excellent support. Btw, does anybody have solved the exercises at the end of the lesson?

[@nlo114]

21:23 - is that the "Ferranti" effect?

[@ohgoditsjames94]

Yes it is

[@noumannasir6044]

Thanks ,It's great explanation.

[@akabaka1993]

Thank you so much for the your videos

[@mohamedshlibek5390]

Thanks you Sir from Libya

[@ernestpkaumba283]

thank you so much sir. ...... Zambia

[@rolinychupetin]

Thank you for the feedback. I was in Lusaka last year, in June. For a week and a half.

[@firasdabbass9999]

Ah, I understand now ! At last ! THANK YOU ! I don't understand why books can't be written the way you explain this in your videos. If there are such books kindly tell me where to find them because the ones I read obviously lack the pedagogical approach you present here...

[@paologrisanti7865]

First of all thank you Sir for sharing your knowledges. Second, someone solved the first problem? If yes here are my answers: S(Source) = 0.704 - j3.874 kVA S(Factory )= 1.346 - j3.7 kVA I considered 125V and 63A as peak values.

[@rolinychupetin]

Thank you for your kind words. AC voltmeters and AC ammeters read the RMS value of the corresponding parameters. The standard in the electric energy industry is RMS for any voltage or current (unless explicitly specified otherwise). That means that 125 V and 63 V are both RMS values. Please, try again. Observe that the active power delivered by the source cannot be less than the active power absorbed by the load.

[@dmehdi2000]

Perfect description

[@88777mm]

anyoone know what changes if we have capacitor instead of inductance next to the resistor ?

[@rolinychupetin]

Even if the "cable" or transmission link joining the source to the load is always an RL link, sometimes in the power industry, for very long links, there may be some series capacitive compensation and you end with the situation that you describe, which makes yours a very good question. In that case, the little triangle (RI, XI) keeps the RI side as before but its XI side points in the opposite direction. I lave it to you all developing the rest of the process of this interesting scenario.

[@eirpcalc]

Excellent, as usual. Thank you.

[@nillakas8457]

You're welcome

[@Rachel-tl8ls]

Thanks from Canada! :)

[@rolinychupetin]

+rachel yu You are welcome, from Vancouver, B.C. :) What school do you go to? If I may ask.

[@hariprasad9071]

Can any one explain me why sometimes we are using tan to find angle in phasor diagram

[@badiace28]

Exelente video señor saludos desde Chile

[@rolinychupetin]

Muchas gracias, Sr. Acevedo de Chile. Un pais que tengo que visitar algun dia.

[@joswarbellidorosas3956]

Thank you so much!

[@rolinychupetin]

You're welcome!

[@yfenfan]

Thank you for the nice video. If I understand it right, the V and I in equation S=VI are vectors, and P=VI*cost(a) are RMS values?

[@rolinychupetin]

S, the apparent power is the product of two real numbers, the rms value V and the rms value I, so S = VI is all reals, no phasors. Now, if what we are computing is the complex power $$\overhang{S}=\overhang{V}\overhang{I}^*$$. the are all phasors (RMS phasors, a.k.a. IEEE phasors). I hope this helps. I used the LaTeX notation to represent phasors with "hats" etc.

[@yfenfan]

Thank you very much!

[@parvezyendigeri3593]

You are welcome. Oh, Zambia, I was in Lusaka last year, in June. I was there for two weeks. I loved the place,, the atmosphere, the people and the food.

[@nathansimps4391]

rolinychupetin oh that's great to hear, for sure we are great people here in southern Africa, I am working on a project of generating free electrical energy by converting the energy possessed by a flywheel in to electrical energy, if you anything in that line of thought that I need ,I would appreciate, thanks

[@maheryagub]
