I'm trying to calculate the zero sequence impedance of the following types of cables: NYY-J, NYFGbF and XLPE-SWA. The only information I presently have on the cablye are its length, resistance, reactance and conductor size. Any help is greatly appreciated. Thanks.
I'm currently performing a power factor correction on a plant, and I've calculated that I need to install 2400 kVAR reactive power correction. I have decided that I would install 5 banks of 500kVAR capacitors. The problem I now face is that I have received quotes on 150kVAR single phase...
ab - parallel to x-axis ab = 1m
cd - parallel to y-axis cd = 1m
Now if i want to determine the step potential at x
Vstep^2 = (Va-Vb)^2 + (Vc-Vd)^2 where Va is the potential at a etc.
Is this correct???

i am having a little difficulty tracking images in two layer soil, when the field point is above the earths surface and the source segment is either in the top or lower layer of the two layer soil model.

I am currently working on a prg to perform grounding analysis of earthing grids. I am using the work by R.J Heppe “Computation of potential at surface above an energized grid or other electrode, allowing for non-uniform current distribution”, IEEE Trans. on Power App. and Sys., 98, 1978-88...
