Today was my wining day about per unit... Many many thanks sir.. Specially loves your teaching techniques... Carry on sir.. I will wait for more video in same style.
Probably for 3 phase single transformer , voltage ratio is already given in line to line so no need for conversion here. We have to consider star delta or delta star only when we have 3 set of single phase T/F whose voltage ratio is given in phase voltage. Am i right?
Sir for transformation ratio is it primary/secondary or opposite? While calculating transformation ratio for T1,sir use secondary/primary but for the the other transformers sir use primary/secondary. Plz CLARIFY
Excelent videos. Appreciate the detail and patience to explain each step. A question about section 3: G3 is generating 20 kV, but the LV side of T3 is rated 22 kV.. what happens with the 2 kV that is not being generated by G1?
I will try to make myself understood. Generator 3 is generating 20 kV. Transformer 3 has a rating of 22 kV on its LV winding (primary side). I would expect the G3 to generate 22kV as well, the same voltage as the LV winding of transformer T3 that it is connected to, as is the case with the other generators, G1 and G2, which generate the same voltage as the LV windings of the transformers they are connected to.
@@ThomasTurkington u alright because transformer never generates voltages but only transform voltages according to turns ratio ...the generator must have to be 22KV as transformer input is 22KV
Sir , for delta winding of transformer the new per unit value = should be divided by 3 . Ryt?? As line voltage = phase voltage divided by root 3. So if transformer with delta star winding will not have same per unit reactance on both side of transformer. Ryt??
very very good! alhamdulillah it has helped me!! thank u sir
never seen such detailed explanation.kudos 👏
Sir please cover all the topics your teaching style is awesome.
Well explained every concept and formula and presentation on its peak ❤
Superb explanation where any teacher can't teach .. great job sir .. i watched ur video and iam thorough in reactance diagram . Thanx lot
gracias!!! eres lo mejor del mundo!!
Today was my wining day about per unit... Many many thanks sir.. Specially loves your teaching techniques... Carry on sir.. I will wait for more video in same style.
Thank you so much Sir. I'm now clear regarding these PU maths.
Excellent video 👌👌.... really helped a lot to me.... thank u so much Sirrr🙏
excelent sir process of teaching is vrvrfvrvr good
it is veryyy informative each step is described perfectly huge thanks!!!
Wow u r the best till yet
Thank you very much well explanation i can't see ever
why rating of T2 is 220/18 on 10:12 ? Also how you flipped the rating of T1?
The Best way one can explain.. Thank you sir 🙏🙌
Clear as in Crystal! Thanks a lot!
Amazing Teacher !!! TYSM
Such a nice explanation!!!!!
it was much much much helpful.. Thankyou so much
Hats off to u sir love u u r too good
Thank you... very helpful
awesome lecture sir🙏👌😍
Thank you very much .well...explanation I can't see ever
Tnx sir....this video is really helpful....hope In future we get more video about on power system....
Thank you so much for the video 👍🙏
How we can calculate the voltage at bus c???????????
very well explained sir , thank you.
Sir some video upload the equal-area criteria with problem solve
tanks for simplifying this
Very good
Sir please make more videos on problem solving
Awesome Sir
Why did you just neglected delta/star conversions while calculating base voltages for different regions?
Jitendra Jha ,,,,,pls consider it if you want to consider........and let me know if you get different base voltage in other regions.
Probably for 3 phase single transformer , voltage ratio is already given in line to line so no need for conversion here. We have to consider star delta or delta star only when we have 3 set of single phase T/F whose voltage ratio is given in phase voltage. Am i right?
yes u r right ....
In per unit method its the great advantage of pu method that whether the system ia start or delta single or three phase the per unit values are same
sir if the bases MVA was not mentioned in the que what should we consider as base?? 35 MVA? as it's the highest value given.
i think you can assign any decent amount of MVA because it will always end up with the same answer
thanks
Sir for transformation ratio is it primary/secondary or opposite?
While calculating transformation ratio for T1,sir use secondary/primary but for the the other transformers sir use primary/secondary.
Plz CLARIFY
yes i have the same doubt , if yours is cleared please explain
thanks so so much for this
amazingggg sirrrr
Was really helfull !!!!!!!!
Hi waht does the " ' ' " mean after X for generators? I need to know quick please anyone.
thank you dear!!!
Thank u sir very useful🙏
Sir❤️❤️
Sir X=10% in no calculation need..!?
Thank u
Awesome
Thank you bro
Thank you.....sir

Thomas T ......... u should understand the meaning of rating........... please refer standard books....
Thomas T ......LV side of the Transformer ....T3 is rated as 22 kV .....that does not mean ....genrator G 3 Must supply 22 kV .....

🥰🥰🥰🥰🥰
i need the refence

Thank You. It helped a lot!
Dada i need 6.16 math solution or solution result
thanks to lord jesus christ i have got good video......thank u sir
