    This is the only video that helped with my problem, thank you so much! Subscribed.

    Thanks for the video
    But I would want to know, what is the phase sequence in this question?
    And if the phase sequence is changed, would the direction of currents through the phases change, hence affecting the formula for finding the line currents?

    Thanks for the great video!
    I was wondering how did u get the phase angel for current I_b? it needs to be 39 according to my calculations thanks

    Hi professor Michel. Can you do more example about unbalanced delta-delta 3 phase system. By using mesh analysis.

    Sir, What should we do if load is unbalanced in delta connected load. What are methods of prevention?

    • @MichelvanBiezen
      @MichelvanBiezen  5 років тому +1

      You need to change the impedance of one of the branches.

    how to calculate total power at unbalanced three phase load

      @@MichelvanBiezen I cant seem to find the video that you mentioned? I would like to calculate power S, P and Q in an unbalanced delta configuration. I use the line currents feeding the load to calculate complex power using the formula S = V x I. Can I simply extract P and Q from this complex power in rectangular form S = P + Qj (considering it is an unbalanced load)?
      Any help would be very appreciated. Thank You.

    is this calculation correct if you have a power source that's also in Delta?

    sir we dont have to multiply the line voltage by root 3 to get a phase voltage then we can start to calculate those phase current or there is no need of that if its a unbalance system?? help sir im confused now because it a deltar connection

      What is the error?

    • @timlongbotham4875
      @timlongbotham4875 2 роки тому +1

      Ib = Ibc - Iab = (-13.75 -j23.82) - (35.20 +j17.61) = 49.95 -j41.43 ___ 64.51 -140.04*A
      Should be
      Ib = Ibc - Iab = (-13.75 -j23.82)) - (35.20 +j17.61) = 48.95 -j 41.43
      Does not make a big difference however because you are presenting this it should be accurate
