    Transformer connected in parallel question

    Thanks for your help. I worked out the loads on the two Transformers connected in parallel and then worked out the difference in percentage overload and submitted my answer and this came back correct. I think it was just the question that was puzzling me I was not sure what it was asking. :)

    Transformer connected in parallel question

    Looking at this again and i have found Full load current presuming 1000v and at single phase: Transformer A = 300000/1000 = 300A Transformer B = 200000/1000 = 200A I know that power factor is 0.45 lag so this is cos^-1 0.45 = 63.25 degrees kVA a = kVA total (Zb/Za+Zb) kVA b = kVA total...

    Transformer connected in parallel question

    For some reason i can't upload the attachment anyways the question is as follows: Transformer A is rated at 300 kVA with an impedance of (0.09+j0.18)Ω Transformer B is rated at 200 kVA with an impedance of (0.09+j0.23)Ω if these transformers are connected in parallel to supply a common...

    Determining whether functions are odd, even or neither

    Just read back over this thread and now it makes sense sometimes you cannot see the wood for the trees thanks all

    Determining whether functions are odd, even or neither

    f(x)=(x^2+2)sin(x)tan(x^2) =((-x)^2+2)sin(-x)tan((-x)^2)) = f(-x) so function is odd?

    Determining whether functions are odd, even or neither

    so last one would be: f(x)=(x^2+2)sin(x)tan(x^2) =((-x)^2+2)sin(x)tan((-x)^2)) = f(x)

    Determining whether functions are odd, even or neither

    so next would be: f(x)=(-x^2)tan(-x^2) =x^2+2tanx^2 =f(x) so f would be odd?

    Determining whether functions are odd, even or neither

    Odd & Even Functions (was thread "Fourier Series") Homework Statement determine if the functions below are odd even or neither: a) f(x)=x^2+2 b) f(x)=(x^2+2)tan(x^2) c) f(x) = (x^2+2)sin(x)tan(x^2)Homework Equations even - f(x) = f(-x) odd - f(-x)=-f(x) The Attempt at a Solution I've managed...

    T to Π conversion for impedance network

    so T to ∏ conversion: Rab = Ra x Rb + Ra x Rc + Rb x Rc / Rc so z x z +z x 2z + z x 2z / 2z = 2.5 z so Rbc = 5z Rac = 5z is this along the right track?
