Per Unit Reactance diagram_Case-1

[@tanveerazizdurbar3269]

Mem your videos are too much helpful. very simply and easily described. thank you so much for helping. From Bangladesh.

[@UshaUsha-rt5rj]

Super explanation mam 👏👏

[@patakotisrinivas1918]

Nice explanation madam

[@EshetuKase]

good lictur go on

[@bsrihari1986]

U r tootorials are exalent madom. Your teaching is 100 times better than my lecturers 🙏

[@yomanthunder]

thanks mam , for going such detail it really helped a lot

[@manikandanpadmanabhan4126]

Excellent 👌 Madam.

[@kanthu9283]

Very nice expalination

[@santoshikulkarni6198]

Very good explanation

[@SinazoJara]

Where were you 😂, I’m so glad I found u yhoooo I’ve been having difficulties in this per unit stuff so glad I found u

[@akhandsingh7719]

Very nice 👍 explanation mam Tq so much Befor seeing this video i think am not able to understand P.U. SYSTEM

[@funrajafun6254]

20:16, In Per -unit reactance of motor, you have taken (MVA)B,new = 30 but the given value is 25? can you explain this mam?

[@Rexton_98]

Mam can Same question we slove by impedance also

[@salaarkhan569]

does the star and delta connection have any effect?

[@psumalatha5659]

Yes. In some cases, they will give rating of single phase transformer. Based on the winding connection we need to calculate for 3 phase. Also winding connection is mandatory for zero sequence network representation which will come in later stages of this subject

[@salaarkhan569]

@@psumalatha5659 ok thank you

[@i_am_mani19]

Madam in some text books calculate p.u reactance using old and new values of mva,kv^2 What is difference between these two methods

[@prog04]

Yeah me to have the same doubt

[@JAYPRAKASH-ez7zv]

This formula used when , reactance is provided in Pu system in question

[@humayonnasir4797]

love you mam 😇

[@SaiSruthi-h6e]

Thank u mam

[@jimgainer]

Thank you...

[@Marliana_123]

Mam your way of teaching is excellent,but views are very less😢

[@sailikhithaanjashwar8638]

Yeah even I felt so 🙂

[@sailikhithaanjashwar8638]

Actually she deserves much

[@abhijitsaha5596]

Thank you so much

[@mohan-kd2tg]

Mem aapne T2 ke liye delta connection me Zb=3*Vb^2/Sb nhi liya h , you have to multipley by 3

[@sumitkunwer6500]

Yes i have same doubt

[@mohan-kd2tg]

@@sumitkunwer6500 bro mem ne wrong kiya hua h , jo tum soch rahe ho vo correct h bilkul

[@psumalatha5659]

Why we need to multiply?

[@psumalatha5659]

Why did you get that doubt?

[@powerful6815]

Mam ith ktu syllabus ano??

[@great_India3344]

Madam, for transformer 2, delta connected side, zbase = 3×Vb×Vb÷Sb Please correct me if wrong. Thank you madam

[@psumalatha5659]

Delta side, phase and line voltage is same. So, vb will become phase quantity by default. So, you will use Sb also wrt phase instead of 3Phase

[@great_India3344]

@@psumalatha5659 but Iph =I÷sqrt3

[@psumalatha5659]

Are you using current in that equation? According to your equation you have only Vb and Sb as given values. In that context I told. If you are using V and current to find Zb then accordingly equations will change
