1 Phase Power Vs 3 Phase Power | Easiest Explanation | TheElectricalGuy

1 Phase Power Vs 3 Phase Power | Easiest Explanation | TheElectricalGuy

Electrical energy is generated, transmitted and distributed in the form of three phase power. Homes and small premises are connected with single phase power. But most of the time you will find that, 3 phase power is more preferred over 1 phase power. The 3 phase machineries are more efficient than 1 phase. But why it is like that? Why 3 phase power is preferred over 1 phase and what is the basic difference between 3 phase and 1 phase power? So, if you want to get the answers and other details about 1 phase and 3 phase power in the easiest way, I would recommend you to watch the video.

    I have 1 doubt sir… Why we can’t connect 4th phase in generator

  2. Rob Troman on October 17, 2021 at 8:35 am

    Thank you

    Got frustrated after two minutes.. English speaking is too poor of quality

  6. mike cubes on October 17, 2021 at 8:41 am

    good video, now it makes sense

  7. The Dude on October 17, 2021 at 8:44 am

    I just love how he says "watch the veedeeouuu"

  8. Hamidreza Shirzad on October 17, 2021 at 8:47 am

    Best Explanation I have heard👏🏻

  9. Steve on October 17, 2021 at 8:48 am

    OUTSTANDING! Thank you!!!

    Thank you sir … Nice explanation

  12. Stephan Hunt on October 17, 2021 at 8:54 am

    Mate you’re a legend. I just found your channel and your videos from three years ago are better than my current lecturers hahah.
    Cheers from Australia

  13. Arwa Kalavadwala on October 17, 2021 at 8:57 am

    Can u make a video on how to evaluate electricity bill and types of charges govt charges on what basis

  14. ZT 1996 on October 17, 2021 at 8:58 am

    So, Why does "n" phase is not introduced?

  15. domain mojo on October 17, 2021 at 8:59 am

    Finally understand what a phase REALLY is!

  16. Faqiih Akra on October 17, 2021 at 9:03 am

    thank you, sir, but what happens if we use 4 phase power ?

  17. tony lanzar on October 17, 2021 at 9:03 am

    very Interesting Tutorials >single phase,three phase powers –electricity.//

  18. la bemba verde on October 17, 2021 at 9:04 am

    Dear Gaurav, I value your work but the phase difference at 4:00 is 180 not 90. The example using 2phases is not correct. You should make a note in the video, pin a comment to clarify the subject or edit the video.

  19. Asgar H on October 17, 2021 at 9:05 am

    Thank u soo much

  20. Vishal Nazre on October 17, 2021 at 9:05 am

    Le Gaurav Tamma, you cleared my post engineering doubt🙏

  21. J Bakes on October 17, 2021 at 9:07 am

    why 4, 5, 6, 7, 8 phase? MOAR POWER

  22. joshua mutya on October 17, 2021 at 9:07 am

    if you say the 3phase is much preferred to single phase. why is that most households use single phase?.. im sure in youre home youre is connection single phase.. it depend bro.. 3phase is costly. it use widely in industrial.

  23. Sunil Basnayake on October 17, 2021 at 9:09 am

    Thanks. Good lessons.

  24. Tom Alison on October 17, 2021 at 9:09 am

    you legend

  25. Avishek Neogy on October 17, 2021 at 9:12 am

    Hey @Gaurav J what is the percentage of losses that are reduced while using a 3phase line over a 1phase line?

  26. Ramalingam Putta on October 17, 2021 at 9:12 am

    Good explanation.

  27. geniusbboy on October 17, 2021 at 9:13 am

    is the power consumption(watts) of one phase motor more than 3phse motor?

  28. Neuron on October 17, 2021 at 9:14 am

    2 times speed is not enough 🤦🏽‍♀️

  29. Blue Sapphire on October 17, 2021 at 9:15 am

    Good job bro 👍🏼

  30. Debayan Tripathy on October 17, 2021 at 9:15 am

    Much helpful

  31. jeffwads on October 17, 2021 at 9:17 am

    I wuv thees veedeeohh

  32. GH1618 on October 17, 2021 at 9:17 am

    I think there is a small mistake here. At 3:54 he shows the 2nd waveform shifted 180° relative to the 1st, whereas it should be 90° according to the description of the generator.

  33. saVRee on October 17, 2021 at 9:18 am

    Great video Gaurav. Slow. Clear. Concise. Thanks for posting.

  34. lohith dunna on October 17, 2021 at 9:18 am

    A very good explanation. Although I am not an Electrical engineer, I have a query. What if I add one more winding to the 3 phase, will it make my peak current even more than 1.5 times the peak current (3-phase). If yes, up to what no of windings can it be increased? If no, what is the reason behind it? Pardon my English, if I did any mistake.

  35. weverton carvalho on October 17, 2021 at 9:19 am

    Fantastic video ! Coming from me you deserve a novel prize, if I understood anyone can.

  36. Luke Castillo on October 17, 2021 at 9:19 am

    I get it now! thanks!

  37. daniel Franchette on October 17, 2021 at 9:20 am

    some remarks (English not being my first language I may have misunderstood):
    Why do you represent the voltages with a phase shift of 180 degrees at 3 min53 of the video by speaking of a phase shift of 90 degrees (if there are 90 degrees the 0 of B must correspond to the max of A).

    it is impossible to manufacture a single-phase alternator that works correctly because of the reverse magnetic fields (Leblanc’s theorem). It is accepted for low powers but the losses become prohibitive for significant powers (> 10kVA). An alternator worthy of the name must be polyphase. This is also why single-phase motors are an energy disaster and limited to a few kW.

    The power on a resistive load in three phase = U.I.1,732 with (1.732 = square root of 3) and in single phase = U.I.

  38. Paochoua Xiong on October 17, 2021 at 9:20 am

    This video would be perfect if u have some captions for it

  39. Ukachi Onyema on October 17, 2021 at 9:21 am

    You are truly a teacher. Many thanks. Quite understood. 🤷 Can someone go for a 4 phase? Coz from the proportions I see above, it will double the power of 1 phase.

    Thank you for sharing! Ever since I had watched your Power Factor video, I subscribed you without any hesitant.

  42. morla gnaneswar on October 17, 2021 at 9:23 am

    Excellent explanation… ❤️

  43. Vishal Sharma on October 17, 2021 at 9:24 am

    What’s the maximum power we can get if we continued increasing phases?

  44. theivanithy raveendrakumar on October 17, 2021 at 9:26 am

    Best explanation for power for different phases. THANK YOU

  45. Benny Lyngdoh on October 17, 2021 at 9:27 am

    Why not more than 3 phase? Say 4 phase or 10 phase?

  46. SUPER5ICIAL Pro on October 17, 2021 at 9:27 am

    Why not 4,5 6 phases

  47. Satyanarayanareddy Karri on October 17, 2021 at 9:28 am

    Why not 4 and 5?
    If the output power is increasing with no. of phases?

  48. Saptadeep Dutta on October 17, 2021 at 9:28 am

    What an awesome work!

  49. ADITYA MAURYA on October 17, 2021 at 9:28 am

    why we have not made 4 or 5 or infinite … phase power ????

  50. Dizzy Izzy42 on October 17, 2021 at 9:30 am

    A quick watch before class. Well explained my guy.I feel a confidence in this understanding now.
