Into the electric field determination, the design, planing and drawing of model process, plays an important role into the early steps of the FEA analysis. The use of CAD software was required as an essential tool in order to carry out the model of the body forming the high voltage device. The following, consists in a descriptive image serial about the cad models obtained during the drawing and planing process. In this case the objects was obtained by the use of AUTOCAD.
Fig.1 Frontal view
Fig.2 Rear View
Figures 1 and 2, belongs to the arrester modeled. First, the frontal view is displayed in order
to see some deatilas about the general shape of both, the aisolator porcelain housing and the metal electrodes.
Next, the second figure details isolator shape, zinc oxyde elements, metal spacers, metal electrodes and air gap. The use of a transversal
cut trough the model, makes possible to apreciate such components as a total device.
