What is positive Sequence, Negative Sequence and Zero Sequence?

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.

hi bro this the best lecture that i ever seen about phase sequence, thank you this solve one of my major problem

[chanakhun]

You are so amazing thank for teachings ( from new engineer in Thailand)

[muhamedmuneer]

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...

[dahmaneahmed]

Thank you so much for your all of the efforts it's very helpful

[sonam.makhija]

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

[ashishvitekar]

Very nice explain and informative video's keep it up
Thank you

[sunnypatel]

Thank you Dear, this is my 1st ever comment and which goes to you. Really Appreciating. Please make videos like this

[ept]

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.

[socalmal]

Thank you for your excellent video. Keep them coming...

[irfanulhaq]

Sir can you explain in briefly, how this will effect in resistive & inductive loads

[giriprasath]

thanks a lot brother... neat and clear explanation.. ton of thanks for you.... and mic is good and audible thanks once again bro

[prabeshray]

Thanks u so much for clearing this confusion

[sampatbera]

Best content on this topic, I ever faced❤

[MajorZero]

7:50 For the negative sequence calculation for condition 2, I am getting (1<240+1<240+1<240)/3 which equals 1<240, not 1. Is the phase angle dropped in this example?

[onlineeducationalways]

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.

[abdulkaderzabarah]

Thanks alot for your efforts. Very helpful!!

[MonemTariq]

At 14:29 you intermixed the angle values of Y and B phases, then how did you get the answer correctly?

[Manas-ro]

is cbct will operate unbalance ondition and zero sequence current is absent

[abanikantarout]

Why unbalanced current setting in relay called/related to negative sequence current ?
Pls explain.
