I have been searching for a good explanation for days. You nailed it. Your English is slow and understandable. Your math presentation is excellent. thank you
Excellent sir. In the last how phase to phase fault doesn't have zero sequence component and phase to earth fault has. This is not clear exactly..this is important please expkain
nice sir... thank you so much...i have many doubts in symmetrical components...now i am cleared sir...but you give only balanced condition can you explain at the time of unbalance fault how phasor angle in I2 I0....
One the best I've ever heard but very sad to see such low subscribers to this great content. I have just shared on my LinkedIn. Request you to please make videos on fault calculation and relay coordination
Sir, I am very late to see this but I understood concept very well, But I have a query that vector will rotate in anticlockwise direction so formulae of I1, I2, and Io will change accordingly... Kindly correct if I am wrong..
NGR connects star point of generator to the ground; it limits the magnitude of fault current returning from ground to star point of the generator for protective relays to easily sense the fault current without damage and operate the protection device, i.e. the circuit breaker.
At 13: 52, Does not the expression for I1 evaluate to zero? (as I understand, vector sum of the positive seq quantities also result in 0). Kindly explain if I am wrong please!
@@electrocean6684 If that is the case, while calculating the I2, you have mentioned as that will come to 0, even with the alpha operator, before dividing it with 3. How come/? Kindly explain.

very very good and to the point explanation, thanks sir
many videos showing pzudo animated videos like water flowing through pipes and other, But u explained the exact real concept
your way of explanation is very lucid and proper.....thank you
this is an excellent explanation. good work
Good explanation in simple terms
Hello, Thanks for sharing, Could you please explain AC voltage value for every mili seconds of 1 cycle.
Thanks again.
Excellent sir.

You are great person

Kindly correct if I am wrong..
Sir please make some videos regarding fault calculation and relay coordination
more videos sir pls
Thanks for the explanation
What is Negative and zero phase sequence, plz explain
Sir upload videos regularly..
How failure of one phase makes negative phase sequence???
in single phase ac , how current flow in negative cycle. please explain
Thanks
Thank you
Adding of 3negative vector sum gives a resultant zero,how u know
Sir, explain about NGT , NGR, and what is the purpose of earthing, what are the different types of earthing

Rajesh T K... No it is equal to load current. Check the use of alpha operator in the next minute..
@@electrocean6684 If that is the case, while calculating the I2, you have mentioned as that will come to 0, even with the alpha operator, before dividing it with 3. How come/? Kindly explain.
I think you had to use the equation as i1= ia + ia.alpha2 + ia.apha. in that way what you told would be true, rite?
I1 = (r + alph. y + alph2. b)/3 will be equal to actual load..
Rajesh T K For I2 alpha operator use is different as compared to I1.
You haven't shown your phasor rotation.
Hindi me bhi video bna diya kriye sir....plz
