1.3 Capacitor- Plate Figure 1-41 Ue8-1 Inner cable 2*ri=10 mm Flange (Flansch) diameter 2*ra=100 mm Flange length la=100 mm Ed=20 MV/m The total voltage applied is 115 kV (compare to the ground). If Δr= const. The lengths of metal pads are l1… l4. If the model is treated as a homogenous field (Plate capacitor) with an isodynamic voltage divide. We will draw the field profile E=(r). 1.3.1 Create a new file. “File”→“New”→ “Electrostatics Problem” 1.3.2 Set problem definition Menu “Problem” Figure 1-42 Problem definition dialogue box la Δr ri ra
1.3.3 Create a new model We treat the model as a homogenous field so it should be a Plate capacitor. 1.3.4 Define conductor and material properties First of all, we must calculate the values of Rx and Lx. I 1 2 3 4 5 Rx 5 14 23 32 41 50 Lx / 519 250 166 125 100 Table 1-5 Calculated values of Rx and Lx Figure 1-43 Nodes To draw such a model, we have several methods. Here I will show you two of them. � Mark one node randomly. Select the node and press TAB, then type in the coordinate of node. Figure 1-44 Enter point dialogue box Then we can see a new point is copied to the new coordinate. � Find (0, 0), use function “copy”
