Inner cable 2*ri=10 mm Flange(Flansch) diameter 2*ra=100 mm<br />
Flange length la=100 mm Ed=20 MV/m<br />
The total voltage applied is 115kV(compare to the ground).<br />
If Δr = const. The lengths <strong>of</strong> metal pads are l1… l4. If the model is treated as a cylinder field<br />
with an isodynamic voltage divide.<br />
Here we will draw the field pr<strong>of</strong>ile E=(r).<br />
1.4.1 Create a new file.<br />
“File”→“New”→ “Electrostatics Problem”<br />
1.4.2 Set problem definition<br />
We can use the default definitions here.<br />
1.4.3 Create a new model<br />
When this model is treated as a cylinder field, we draw the cross section <strong>of</strong> the cable. First<br />
step, draw 6 concentric circles.<br />
Calculate rx <strong>and</strong> lx first, <strong>and</strong> then mark all the points in coordinate.<br />
