    Figure 3a shows a 50 Hz, high-voltage transmission line

    Also Z1= Z3 =1/2 (R+jωL)δx and Y2= (G+jωC)δx Where δx= line length. But I don't know how to get from the matrix to Z1, Z3 and Y2

    Figure 3a shows a 50 Hz, high-voltage transmission line

    Homework Statement Figure shows a 50 Hz, high-voltage, transmission line. The relationships between the sending and receiving end voltages and currents are given by the complex ABCD equations: where 'S' stands for sending-end and 'R' stands for receiving-end (a) Given the parameter...

    Engineering Delta and star transformation of AC circuits

    So i have worked out that each of the impedance's would be 7.5+j7.5 Is this correct?

    Engineering Delta and star transformation of AC circuits

    For part C would the circuit look like this (see picture) before I make it into 1 single Y load.

    Leq = (L1*L2-M^2)/(L1*L2-M^2)Hope this helps

    Brilliant Thank you
  8. S

    Leq = (L1*L2-M^2)/(L1*L2-M^2)Hope this helps

    For part d) i have this (done on mathCAD) is this correct?
  9. S

    Leq = (L1*L2-M^2)/(L1*L2-M^2)Hope this helps

    Thank you gneill
  10. S

    Leq = (L1*L2-M^2)/(L1*L2-M^2)Hope this helps

    I'm sure i am being silly but what does Jw stand for?

    Thevenin's Theorem: Solving Homework Statement on Load Current

    I am currently on part c) and have converted each voltage source and series impedance into a current source and parallel impedance using Ohms Law, I = V/Z which i get 103.75 for v1 and -J69.17 for v2. Then combining them to get 103.75-j69.17 as my voltage source. Then to combine J4 and J6 which...
