plz correct that..u have to take 1 pu..bcoz at fault point prefault voltage is 1pu.. or you can take SCMVA=Efpu*Ifpu + Empu*Impu..both method will give you 750MVA..ok

[@competitioncurrentaffairsw2128]

means 0.9638 ki place par 1 p.u lena hain?

[@mohdaqib784]

ok sir now i understand but method 3 is very good

[@manishmeena2642]

Tnqu sir

[@gateaspirant3178]

@@mohdaqib784 ...method 3 sai apko 750MVA aya kya?

[@sanjuthakur7221]

sir Efpu*Ifpu+Empu*Ifpu ..sir this is not clear ,answer is not coming

[@GeniqueEducationTeam]

done for today...uploaded 3 videos in power system. Watch it and make proper short notes. All the best.

[@therosuperhit]

Thevenin concept k liye short notes me kya add karenge sir ? Complete problem jo aap btaye ???

[@GeniqueEducationTeam]

jab prefault current diya rahe to go for thevenin concept..itna likh lo.baaki procedure to lecture me bata diya hu..ok

[@therosuperhit]

Thanks sir ,I did that..

[@078_surajyadav6]

Sir Ipu mein angle kaise aaya

[@udaymehta8917]

WHAT A METHOD SIR... VERY EASY TO SOLVE PEHLE ME AESE QUE DEKHTE HI QUIT KAR DETA THA, QUE ME ENTRY HI NAHI HOTI THI. BUT AAPKI METHOD SE TOH SIR, KOI BHI QUE ME WITH FULL CONFIDENCE ENTRY BHI HOGI AUR ANSWER BHI QUICKLY MIL JAYEGA THANK YOU VERY SIR

[@GeniqueEducationTeam]

most welcome..ab share karte raho..taaki baaki ko bhi aasan lage..all the best.

[@moshfiqurerahman8144]

I have never seen someone who's basic is so clear. Thank you so much sir

[@shivpratap2390]

Best ever concept....a perfect combination of power system and network analysis....

[@gyansarovar1698]

Superb sir, बहुत अच्छी तरह समझ मे आया।

[@someshthakur4084]

How did you assume voltage of bus as 1 p.u? The base voltage could be different for reactance p.u values

[@vijayprajapati1040]

SIR POLAR TO REC AND REC TO POLAE TAKES MUCH TIME...SIR USKE BARE ME KYA KRE...

[@mahendrameher3522]

What a concept sir!!!...great...

Thanks Sir, for giving wonderful lecture

[@muhammadibnwahid6405]

This video was uploaded on my birthday and the video made me like the the way he explained.

[@bariyanayan816]

an amazing concept with extraordinary .... thank you, sir ☺

[@sambitkar8994]

samajh aa raha sab sir , bahut ache se... easily Avi sab samjh Raha hun

[@Hero123-w9v]

Sir your teaching is awesome...thank u sir...

[@remakeoriginals8758]

I have never seen a teacher like you,you are amazing ,sir☺️ Kya jabardast padhate ho

[@somlaeducations3308]

dear sohail ansari sir.kindly one request..please explain on how to resolve this problem on Calsi along with explanation, because so many student confused sir...i hope this problem explain in upcoming lectures ..thank you so much sir

[@GeniqueEducationTeam]

we will make one video on how to use online calci..dont worry..

[@somlaeducations3308]

thankyou so much sir@@GeniqueEducationTeam

[@samiulemu7003]

sir i learned a lot from you, here, Vf(p.u.)=1 p.u.,Zf(p.u.)=inv(inv(0.1)+inv(0.2))... If(p.u.)=-15jp.u.....gives the same answer...may be if Vf(p.u.)=not given and Eg,Em given this procedure could be helpfull...and as you said pu is only defined in per phase...then Ef(p.u.)= (11/root(3))/(11/(root(3))) rather than 11/11.and one thing is fault cuurent always line current?

[@user-vk1cz3je8x]

thevenins voltage is 1pu and thevenins resistance is j0.1//j0.2........short the terminals of this thevenins network.......we will get 1 p.u./j0.066667 = 15 at -90

[@unknownsinger7366]

Sir short circuit MVA(at bus) is coming out to be 750 by MVA method and 751 by Ef*If method. But you wrote it as .9638*15 which is somewhat faulty, because even if we see MVA rating of CB placed near to generator we have to see fault current flowing at that location and that is 10 pu, so .9687*10 at gen side, 1.0796*5 at motor side and net sc MVA will be addition of both and it is 751 MVA...by MVA method it is 750.. Kindly mark your comment sir and clarify my concepts... Only dependent on your lectures

[@tareqaziz3020]

Very important topic and very easy method to understand. Thanks Sir

[@anilmanekar]

Very interesting, you have power system so easy sir hates off

[@souvikbera5845]

sir zyada se zyada possibilities solve karne ka koshish karenge jisse ki kam questions maximum concepts aur clear ho jaye.

[@abhisekrout8522]

@ 27:47 Why is SCMVA= E(gen)p.u. * If(p.u.) ??? Sir, but the back emf of the synch. motor also accounts for the fault current?? So, why isn't SCMVA= E(motor)p.u. * If (p.u.) ????

[@socialmanager865]

Sir your way of teaching is ..amazing

[@kamarajup6713]

Shortcut method is good and your explanation is very good

[@mayankojha2333]

Sirji teeno method se aa gya SCMVA ( I took Ef actual as 1 pu in calculation of SCMVA in pu)... Thankyou sir for this wonderful concept.

[@GeniqueEducationTeam]

most welcome...share karte rehna..all the best.

[@ManOn-hb2xu]

Mayank can you kindly tell me how you got answer from MVA method. I got answers from other two methods but not getting from MVA method .

[@mayankojha2333]

@@ManOn-hb2xu you might be doing mistake in adding MVA in parallel... Check ur calculations.. you will get it

[@ManOn-hb2xu]

Thanks a lot Mayank for your reply , actually I was doing mistake in taking MVA, I took 25 instead of 50 MVA for 2nd circuit(motor circuit).

[@debapriyachakraborty8654]

Just started watching this crash course. It is really sad that I will not be able to complete this before GATE 2019. Nevertheless power system is becoming so much easier. I will recommend this lecture series to my friends. Thanks a lot for making this freely accessible. Shall comment again if I am able to solve some problems on Power System in GATE 2019. :-)

Sir during fault motor also act as source then why in d calculation of SCMVA you only took Eg(pu)×If (pu)

Great video... Need some more

[@nandanmishra7699]

Sir when you replace 1 p.u voltage by 1 p.u voltage source (18:20 min)....then how current flowing in generator and motor will same????...here, through 1 p.u voltage source some current must flow.....plz sir give me reply....plz plz....

[@shubhamsharma-hh4vz]

Sir overall is excellent can you please give2 or more examples questions in each videos.

[@krantiveersingh12]

bahot achha samjhaya , thank you

[@pavan1685]

Sir , power wale formula me agar hum active power per unit find kar rahe hai..to mva jo diya hai use hi sidha 0.8 se multiply kar de to dono quantity MW me ho jayegi..to per unit ka answer change ho jayega?????

[@abhisekhrawat3183]

Sir last wale question me SCMVA agar MVA method se nikalu to usse ans thevenin method wale ke equal nhi aa rha hai......

[@dagamrajam4268]

∆ig, ∆im find Karna exllent concept hai sir,,

[@SajidHussain-ux7vc]

1NO..SIR ji

[@TheThrillingGuy]

So if there is 2 pu at fault then we have to take -2pu in ckt?? Or still to take -1 pu

[@GeniqueEducationTeam]

Whatever the pre-fault voltage u are getting at fault point. U have to take negative of that

[@pradeepdauhare6490]

Sohail sir Plz guide how will find phasor angle without calculation as you mention in each solution.

[@arvindkumarsonkar3115]

sir please clear how you write value of I or E in + or - angle of....??
