        abstract = {Different materials—solid, liquid, and gaseous—are employed as insulation in high voltage electrical systems to guard against equipment failure. Because of the limitations of the production process, insulating materials typically always include certain contaminants. Additionally, these contaminants manifest as voids, fractures, poor conductor profiles, etc. It is frequently noted that there are air bubbles inside the insulating material, which is very undesirable as it creates a weak spot inside the insulator. Additionally, the insulation of high-voltage equipment eventually deteriorates as a result of the combined effects of chemical, electrical, and thermal stress. Therefore, a weak zone inside the insulator generates a partial discharge anytime high voltage stress occurs, which ultimately results in equipment damage.
The PD activity of two distinct insulating materials—GLASS and GLASS PYREX—has been studied and compared in this work.  An electrical circuit model is utilised for that.  When the insulating material is subjected to a homogeneous electric field using a plane-plane electrode configuration, a tiny cylindrical void is assumed to be an impurity.  Since the geometrical arrangement of the void substantially influences partial discharge, this analysis takes into account the relationship between apparent charge and void height and radius.  Two solid insulating materials exhibit PD pulse magnitudes at various applied voltages. The MATLAB environment was used to complete the simulation.},
