Modeling Effects of Partial Discharge Void Geometry on Various Dielectrics

Numerous solid, liquid and gaseous materials are used as insulations to protect power equipment. Most materials are not perfect and contain some impurities that could lead to internal failures over time, called partial discharge. Detection and measurement of partial discharge is very important to spot these failures early on inside the material. In order to study the PD characteristics we use MATLAB SIMULINK to simulate a developed model, the model is used to study the effects of void
^,
s geometry caused by the PD inside multiple dielectrics., the work is focused on the results of partial discharge in 6 dielectrics (air, rubber, epoxy resin, XLPE, paper-insulation oil-filled, teflon) with a single cavity as defect, we study 5 void shapes for each material (cylinder, cube, cuboid, sphere, ellipsoid).
