in 31:26 the right side of a inv V curve of alternator in lagging .. so it should be as delta or input power increases pf goes from lag to lead via unity. which is also said by sir in previous section and also seen from the phasor.
Please give solution on this concept of question is An alternator operating on infinite bus bar at 0.8 leading of if the load on alternator increase by keeping excitation constant then pf,Ia
Hello ankit bhaia aka sir.. Actually I wanted to ask you a question in parallel connection of alternator and infinite bus bar.. Incase of loaded condition,why we say pf varies from lead to lag when excitation is varied and why we say pf varies from lag to lead when steam input is varied... actually in your video we can start from any case of pf i.e you have started from lagging condition,but I can start from leading pf condition..so it's up to us from which pf we start our analysis...but you generalised it in a statement
Load is increasing from left to right. So instead of concentrating on lag and lead just draw a vertical line cutting 3 inverted curves. You will notice that pf first increases then decreases.

Yes.you are right.moving along a constant field current,for increasing power,pf should move from lagging to leading,same trend as said in the phasor.

You are amazing sir...machine god❤️
Best teacher
Ty ♥️ sir
Complitely understoodable

THANKS sir ji
Good morning 🌞
As Mr.Soumyadip said,the pf trend should be lagging to leading,for increased value of power.

You are supreb sir❤
Good lecturr
Thank you sir ❤️🔥🙏🏻
Thanks for this sir
Sir droop characteristics ka video dal dena
Good morning
Sir ko lgta hai ki hum log Ganesh ji jo itna fast likh lenge jaise vo bolte hai 😅
sir plz provide droop cs
Nice content
🙏
Sir, 19:00 lag - unity - lead power factor hoga
Navneet Kumar lead unity lag..as you can see ia3 leads ea3 by f3 angle
