- What is positive Sequence, Negative Sequence and Zero Sequence?
Positive sequence
The system follow the power system.
Negative sequence
The system which is oppose to the power system.
zero sequence
The system which will not follow or oppose the power system

Thank you for your excellent presentation on positive, negative and zero sequences. I have read up on this topic in the past but after reading the material I still did not have a clear understanding the sequences. Thanks to your well presented information it has helped me better understand the topic. Thank You so much for sharing.
welcome
Sir can you explain in briefly, how this will effect in resistive & inductive loads
i will try to make for you sir
I have one doubt...why u take " a "as 1
its formula
Sir why negative phase sequence occur ?
due to Reactive power
Thank you for wonderful lecture. Can u explain what are the sequnce available in different fault.like phase to phase ,phase to earth,3 phase fault,3 phase to earth, etc...
yes bro soon i will make video
its hard for me to understand indian teachers,because of their accent makes it difficult,since it sounds like their language. i know indians are very good at their science but the accents makes it hard. no hard feelings.if they try to inprove pronunciation will be better. thanks
thank you for your commands i wil try to improve
Well we will continue to have different accent just like you can't speak Indian languages with Indian accent...Try to understand
Then go and learn from the teacher who have your accent 😂😂 , why are you coming for a indian teacher ? Are all your people dumb ?
Thank u so much for explaining wonderfully.can u please tell me how the positive and zero sequence impedance is decided for 220kv Transmission line if the conductor is zebra (for calculation of zones impedance) kindly answer my ques
i will make one video related with this.
Sir symmetrical and unsymmetrical components video explain very nice.
Sir please add video different types of faults in 1phase to ground fault,
2 phase to ground fault, 3phase to ground fault, 2phase fault, 3phase fault in positive, negative, zero sequence phasor diagrams explain.
sure bro i will make for you soon.
hi bro this the best lecture that i ever seen about phase sequence, thank you this solve one of my major problem
welcome
FOR MOTOR REVERSE Direction WE REVERSE ANY 2 PHASE IS IT CREATES UNBALANCE CURRENT IN MOTOR FEEDER
no it will not create unbalance we will change only R and B 2 phase
Thank you so much for your all of the efforts it's very helpful
most welcome
Dear one, good effort!
But, your waveform and the PHASOR expression DON'T match.
In your waveform : Y leads R by 120 deg, but
In your phasor : Y leads R by 240 deg.
Please maintain consistency in the waveform and PHASOR expression.
positive sequence - first start with r follow with y and b and also RYB, YBR & BRY they all positive sequence
negative sequence - RBY, BYR & YRB this combination are negative sequence
if i am not wrong.
if still you find mismatch with me you can share link to me for ref. thank you.
7:50 For the negative sequence calculation for condition 2, I am getting (1
at 7:50 i am explaining negative seq current value. thank you.
Sir
Super class
thank you
EXCELLENT SIR
thank you
Sir, phasor Rotates in Anti Clockwise Direction But here you have taken Clockwise Rotation, then in that case after if I put my finger on R( 0 degrees) then B is coming and after that Y is coming is it right.
R- 0 , Y- 240 and B- 120 angle in this way is easy to check.
Thank you
You're welcome
is cbct will operate unbalance ondition and zero sequence current is absent
if unbalance in R, Y, B then it has to take other path only N , thank you .
I think you plot your phases wrong in time. IB and IY need to be replaced with each other.
Who is with me?
R is in vertical so it is making confuse for you image and rotate the phase diagram R in Horizontal then it will be clear for you .
Why unbalanced current setting in relay called/related to negative sequence current ?
Pls explain.
due to unbalance also cause by negative sequence current
hi annan what is A=1amps angle 120
fixed value bro
@@baranitech1026 ok annan
Incase R, and Y ph i'm injecting 2 amps , b phase im injecting 3 amps.....In that case also the value of a= 1 angle 120 deg only ?
thank you so much to share this with us. Can you create a new WhatsApp group?
i will make
Congratulations! Very well explained
Thank you!
At 14:29 you intermixed the angle values of Y and B phases, then how did you get the answer correctly?
your real good view here i make mistake on broad sorry
Sir,
Why does zero sequence current cannot flow without a neutral path?
3Io=In .so without IN there is no Io
10:05 🙏
Can you show the calculation step with calculator
i will make one more video regarding this with more steps
Very nice explain and informative video's keep it up
Thank you
Most welcome
Thanks
You are so amazing thank for teachings ( from new engineer in Thailand)
thank you and welcome
Thanks u so much for clearing this confusion
My pleasure
Very good explanation
thank you soo much
Good 👌👌👌👌👌👌👌👌👌👌explanation
Welcome most 🙏
Thank you, sir. Well explained!
welcome
Thank you very much ❣️
You’re welcome
Excellent delivery
thank you very much
Thanks alot for your efforts. Very helpful!!
Welcome
Thank you Dear, this is my 1st ever comment and which goes to you. Really Appreciating. Please make videos like this
thank you and welcome
not enough subtitles
I will try for making subtitles
Really great job sir....
thank you
Hi, I like your lecture
Thank you
Very nice...
Thank you and welcome
Good one.
Thanks!
Thank you!
welcome
Thank you
You're welcome
Thank you for your excellent video. Keep them coming...
thank you and most welcome
What is A ? And, How a = 1 < 120?
its formula used in sequence much deeper i don't know i will try to find thank you
@@baranitech1026 Ok
Well explained ! Thank you !
welcome
Thanks sir.
Most welcome
Honest effort sir...my gratitude
thank you
thanks a lot brother... neat and clear explanation.. ton of thanks for you.... and mic is good and audible thanks once again bro
welcome bro.
thank for yor explaining but could you tell me why we set the value of earthfault protection between 30 to 50% of rating current
earthfault protection should be from 5% depends on its application
Best content on this topic , I ever faced❤
thank you and welcome
Thank you❤
welcome
Thank you 🙏
Go on
welcome
I cant thank you enough !!
