Professor D P Kothari Sir is my favourite professor. He is the real source of knowledge of Electrical Power System Engineering. ❤❤

[@nmdalal21]

This is very useful lecture for power system engineers. Thank you Kothari Sir.

[@vivaldodcastro7040]

Im so thank, for these usefull lessons Sir! Im loving with how amzing are the study of power system analysis. Sorry for the mistakes, im not a native speaker, portuguese is my official language.

[@MayankKunwar93]

thank you sir! 😊 Love your lectures and the book Modern Power System Analysis too.

[@subhankaradhikary6969]

old is always gold ❤

[@atulgpt]

examples provided by sir is really hilarious...:D

[@Gokool_wid_Life_coz_YoLO]

It's a good lecture with bits of humor, easy to understand and simple explanation.

[@thundafundamentalist]

Amazing delivery and method of teaching!

[@umangishchumun4886]

sir u r incredible.....am from mauritius....i have been struggling with this chapter as lectures were too bad...

[@tceterex]

I agree with all the comments posted earlier than mine. Greatest lecture!!

[@knowingtruthisbliss2717]

YOU ARE GURU! Keep making these power systems lectures, please.

[@pranjitxhandique]

who is this scholar. if only i could make him my guru...

[@ManojKumar-bo3xy]

D.P Kothari

[@himanshushekhar866]

Is this for UG?

[@nnennahannahorjiugo1986]

This is amazing. wow!

[@TheGetdaya]

thank u sir" u r great, great lecture,if studied from ur class i would become like edison,,

[@vikeshkumarmishra1981]

I thank to you from core of my heart.

[@satendrakumarMATLAB-TUTORIALS]

A must watch for "All the NIT's profs."

[@anantgavas2310]

Thank you sir! I use your book only for power system analysis,but only thing is that it has only 1,2 sums solved in book

[@pg-6]

such an easy language with basic concept ...

[@AshokYadav-sh8pk]

Brilliant Lecture.. Sir made the topic easy to understand!!

[@dibyendubanerjee9757]

Very good lecture, now load flow has cleared to me.

[@dr.rajamasoodlarik8680]

very good and basic lecture i had learnt alot

[@shohebabulhossain2115]

BEST LECTURE VIDEO

[@gosulaudayshankar5126]

why conjugate of current is taken in complex power

[@jakemillyard7585]

The current phase angle (+/-) corresponds to opposite power angle (+/-) . Looking at an example of a voltage source with one ideal inductor (size does not matter) you will see the that the current angle becomes -90 degrees (current lags voltage) a lagging power angle corresponds to positive reactive power. The opposite is true for capacitors. So you can see the current angle is always exactly opposite the power angle (assuming voltage angle is 0). So to properly calculate complex power (S=VI*) you would need to use the conjugate of the current to calculate the complex power in the correct quadrant. Hope this helps.

[@rohitsrivastava2532]

To obtain proper sign for reactive power it is necessary to find VI* rather than V*I which would reverse the sign for Q.

[@avineshkumar7137]

AWESOME EXPLANATIONS... GREAT LECTURE...

[@messengernganga2035]

thanks for all Sir,i have problem witn my network, my network got 148 bus but whem i tried and simulate it all network has changé the color ( it's became yellow) in fact ,i don't what's happen

[@mehedihossenlimon2653]

you are awesome, professor!

[@udaykumarsuryawanshi5247]

roti chapati fulka ...hilarious sir

[@superkidz8284]

This is an amazing explanation!

[@SSVISEN]

Awesome Lecture .. Thank You Prof. Kothari Sir

[@paridalipu]

Revising 3rd time......

[@oscargonza7038]

please do what you can to Spanish subtitle porfavor lo puede subtitular al español

[@jeswingeorge4664]

excellent class...Thanks a lot dear sir.

[@suddendeath3135]

After so many years we are still studying the same things

[@AZZEDDINE2801]

It's an interesting work. Thank you sir!

[@shiprabhanu9562]

Thanks professor!

[@NetramMeena]

very very helpful thank u sir

[@jitendrasinghbhadoriya153]

Load flow is online solution or offline

[@aydoganozgur]

I'm Turkish and watch your lecture perfect

[@Arshath13]

♡ from India 😊

[@asadmughal8205]

Give me a example of 10 node network

[@PedroPedritoZZ]

great video i´m not a native english speaker so this accent is hard to understand for me

[@milappatel2872]

How to find angle plz ans

[@subhankaradhikary6969]

❤❤❤❤

[@kingworld2002]

I feel little bit confused during middle of the section

[@ashishrathod5497]

How to see all lectures from starting to end all lectures please give me information if anyone know...

vary vary good and thanks

[@rinuravikumar]

Thank you Professor

[@sel60-pravinkhade44]

God 🙏🙏

[@Dreamwillllow]

Thanks Sir.

[@thaerabdullah9629]

thank you very much

[@yabhishekreddy]

A politician can because someone else pays for it :)

[@prt2jriit]

Thanks sir..

[@gamex6120]

New courses should have been uploaded

[@sureshgeetha9655]

thanks sir

[@pranjitxhandique]

sahashra pranam...

[@TheGetdaya]

thank u sir"

[@kittu84]

nice sir

[@tareknagla3141]

EXCELLENT

[@debebezeleke6913]

debebe

[@toptrendinginhindi3673]

Y12 = Y21 = -Y12 SO Y12 = -Y12 😂 31:07

[@prt2jriit]

Please analyse the terms properly.. Don't co relate the unnecessary terms

[@Arshath13]

Would you mind if I correct you by telling that what he actually wrote is "Y12=Y21=-y12" ? So clever at finding mistakes huhh ,well I guess you lost your concentration in that part ,better watch the lecture again (:

[@saurabh3847]

Anyone from b tech

[@Arshath13]

I'm here...3rd Year Electrical Engg. !

[@vivaishah]

its good, but he's too slow and boring

[@srinivasaraoannavarapu1692]

thank u sir very nice lecture

[@alastair07]

thank you sir..

[@user-ho9xt1gr5m]

thanks sir.
