3-phase system input voltage

  1. Aug 23, 2015 #1
    • members are reminded that working should be presented in Latex and not in images of handwriting; only figures should be in image form
    In the three phase system of Fig. 8.4, calculate the magnitude of the line
    voltage V and the input power factor.
    Data
    V 1 = 400 V, Z ̇ L = 0.1 + j0.2 Ω, P 2 = 10 kW cos φ 2 = 0.6, Z ̇ 1 = 5∠60 ◦ Ω
    delta connected, f = 50 Hz.

    The results are:
    V=462.76
    Cosphi=0.506

    In the image attached there is my solution. Could you please tell me where is wrong? image.jpg

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    If you could upload a more clear picture I'd be happy to try help you. Just finding it difficult to see the circuit etc.
