SM35 Parallel Operation of Alternators under Loaded condition

[@ठाड़ाचेला]

वाह मजा आ गया सर जी इसमे तो,ये सच मे मैने पहले नही पढ़ा, धन्यवाद

[@johnhonai4601]

Thank you, Sir. I used to learn byheart "Excitation Increase, KVAR increase". But this diagrammatic representation helps very much.

[@rupaliukey2909]

Salute sir ,the way you are teaching is excellent ,I have done coaching in topmost academy but still i get something new from your lectures , no one explained this in detail ,tysm🙏

[@dmo4657]

Sir, at 17:10 you have taken the angle ⌀2 from the kVAR axis. If power factor is decreasing then the angle ⌀ is supposed to be increasing.

[@surendrakverma555]

Excellent lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏

[@satyavara6276]

Excellent explanation sir

[@sheshusmart3300]

Tq you saved my sem

[@visheshsingh1238]

Nice explanation sir

[@gustavomarcelo7250]

How do we carry out the same analysis for 3 generators?

[@prasannakumar2638]

8:02 Since KVAR 1 and KVAR 1' are in negative y-axis, KVAR1 should be greater than KVAR1' right?

[@dr.tirupathirajukanumuri4451]

No

[@pudurusuresh8644]

Sir at 22.23 why the two machines characteristics are falling down

[@arindamchowdhury4734]

Sir.. when load is connected .. if I increase excitation of one alternator.. then it will be accelerated.. because inorder to maintain same speed if excitation is increased then power angle(delta) should be reduced.. so ..will the whole combination will be distabalized??

[@petchu2002]

Dear sir I have one more confusion that whenever we draw voltage vector for two alternator in opposite direction ,it means angle between them is 180? supposed to be both are peak at same instant ans zero at same instant means zero phase angle.

[@MANOJKUMAR-mb2uw]

One shot clear🙏🙏🙏🙏

[@muhammedanfas7873]

thank you sir ,thank you very much

[@maheshwarreddy3656]

Sir when alternator connected to bus bar if we increase prime mover input why speed is not changing?

[@3dgiftz]

Good

[@shaileshbirajdar1963]

👏👏👏👏

[@jassalg7169]

Sir we can maintain stable power factor during parallel operation of alternator Sir actually during parallel operation when first alternator execution is increase then power factor of first alternator is leading and secondary alternator power factor automatically leading. Then second machine is tripping frequently due to reactivate power Sir how to solved this fault ? Pls reply 🙏

[@petchu2002]

Dear sir Please clarify that at first vector diagram IxR and IxX why they are being drawn at this direction.IR might be in phase with V. Please explain the reason why they are drawn at that angle. Thanks

[@petchu2002]

Dear Sir thank you very much for clarification and response. And I have one more confusion that whenever we draw voltage vector for two alternator in opposite direction ,it means angle between them is 180? supposed to be both are peak at same instant ans zero at same instant means zero phase angle.

[@sasidher8922]

Sir,what happens if prime mover has rising characteristics ,can't they share load equally in this case?

[@sasidher8922]

Sir, can you tell reason for it?

[@er.imransiddiqui]

Sir, how can we say that the magnitude of generated voltage does not change with frequency although the emf equation(E=2.22 f × phi × Z) has the frequency term and what is justification for the change of phase of emf with frequency?

[@er.imransiddiqui]

@@lecturesinelectricaleng I watched the video. What I am still thinking is that when the speed of the prime mover changes the frequency as well as the induced voltage must change. Because E= 4.44 f × phi × T.

[@er.imransiddiqui]

@@lecturesinelectricaleng Ok sir. But then here in the second case you have assumed that the magnitude of E1 and E1' are same, only phase is changing. I want the reason for both - (1)why magnitudes have been considered same here and (2) what is the proof that phase changes with speed/frequency?

[@er.imransiddiqui]

@@lecturesinelectricaleng Ok Thank you Sir.

[@pbsaikumar3553]

Sir,please reduce the speed while explaining the any concept

[@dmo4657]

Watch at 0.75 speed. The speed is fine.
