This was the one topic I never understood when going through my electrical engineering degree. I got curious about it recently and looked up some videos about it. Thank you for explaining it so well!
Loved your explanations. It did make me feel why didn't I get this before as you simplified it so beautifully and helped me learned. Keep up the good work. 👍🏻👍🏻
Towards the end, you said that Power Transmitted is the same in both cases. Based on my calculations, the formula is the same: P = root(3) * U * I but, I is different. So, Power in delta is 3 times Power in Star(assuming loads are the same). Correct me if I am wrong.
Thanks for the explanation. what do you mean by indicating that Y-Connection is needed when a neutral and "two seperate voltages" are needed. As I know in distribution systesms there are 3 voltage lines and a neutral; please clarify for me this point. Many thanks
@@GauravJ Hello, our teacher. Thanks for the video, but it explains when neutral is not needed. Whereas, we want to know why two separate voltages are needed in the star connection while internationally we use 3 separate voltages and two as you mentioned at 6:10 in your video.
Hello sir , your videos are very helpful and well prepared with very nice explanation. I kindly request you to please make videos and explain BRUSHLESS GENERATOR , AVR , circuit breaker. Thanks in advance.
Thanks very much sir. Please you should work on a playlist for beginners like I, I'm confused on what to watch because all the videos refers me to a previous video. IN SUMMARY PLAYLIST WILL BE GOOD. Micheal Van Bizen does good Playlist and Numbering. Still you're the best for Electrical Engineering
you explained star connection in a excellent way but delta i didnt understand and one more thing when you used kirchhoffs laws both 1 and 2 you can easily explain that also within 1 min of time with this topic . thanku for the video
With some large motors I have worked on, they transition from, if I remember correctly, Delta to Wye during startup. I think it is something to do with the in-rush but, I would like to better understand these.
Compressor engineer here! You're right, big motors usually start in star & move to delta. This is because in star, all 3 phases are connected in one point, which means the phases inefficiently "pull" on eachother & can't deliver the full magnetic power that 2 opposing phases would. In delta on the other hand only 2 phases are ever connected at a time, & as mentioned earlier these are two opposing phases, which deliver the strongest opposing magnetic powers. This means that the motor will start with all 3 phases acting in a weaker form, as to not burn out any wires trying to overcome inertia. Then, once the motor's up to speed, it switches to the stronger delta configuration & runs with maximum efficiency. Hope this made sense! If not there are probably videos out there explaining it better than I can 👍
@@oscarcameron3274 It makes perfect sense. I'm a HVAC Mechanic, retired from a large school district. I've troubleshot a few of these but, never fully understood the science. That also explains the need for resistor coils. Thanks for your reply.
why short circuit does not happen when we connect the three phases in a star connection to form a neutral point. I havn't found an easily understandable answer to this question so please help me in this regard.
Good morning sir.. Please explain below statement... If 2 different phases meet then it short circuit. But how can a 3 different phases tied to neutral point in star connection can't get short circuited?

Then you didn't earn an electrical engineering degree.
@@dsdave07 Oh. Okay.
@@zzApotheosis Sorry; I was harsh.
@@dsdave07 What did you specialize in for EE ?
I'm in my first year of Comp Eng. that includes courses from EE and we're already learning this. How did you get by without understanding this, lol .
I'm a mechanical engineering graduate but I loved ur videos the way u explained is superb bro

This video is good. With the delta system transmission lines, where do you get your neutral to supply the consumers? Do you also need a ground?
Hi.. delta system is only used for transmission... For distribution to customer always star is used
Really nice video..

This is a great video. Why would you connect a motor in a delta or wye? Most motors have ability to be connected either way? Thanks.
much appreciated sir
WONDERFUL
Thanks, amazing, very good video
I thank you sir 👏👏🏴
you explained star connection in a excellent way but delta i didnt understand and one more thing when you used kirchhoffs laws both 1 and 2 you can easily explain that also within 1 min of time with this topic . thanku for the video
Lol the hard part is the proof by Kirchoff law... so better pass it as SIMPLE MATH in videos
Excellent... thanks a lot
Please do a video on contactor and overload relay used for 3 phase motor
Thank you.
Beautiful
Excellent - i think you may have cleared up some long held misunderstandings for me .
Nice bro you explained it very very well
Impressive 🤙🏻🤙🏻🤙🏻😎

U just rockd bro ?

Can you make a video about vector group
Thanks bro.....
Now have understood the difference between star and Delta connection
Thanks sir u are amazing
This was great :)
Dude you really good at this! wp
Thanks
Nice video
Thanks for great explanation. But i have 1 question, what is E in power apparent formula?
Namaste 🙏
Thanks bahi
Very good
Y-Y connection is used in high voltage transmission line @6:44
Good morning sir..
Please explain below statement...
If 2 different phases meet then it short circuit. But how can a 3 different phases tied to neutral point in star connection can't get short circuited?
