Abstract: Widespread use of heavy duty machinery in industrial setup has rendered the power supply and insulation network highly prone to various types and degrees of damages depending on the type and intensity of workload. Insulation damages generally lead to the production of partial discharges. This may be effectively used for online monitoring of insulation plant thereby leading to a substantial decrement in the unwanted downtime. In this context, the present work explores the various causes associated with the incurrence of partial discharges in an insulation system and consequent effects of the same. Furthermore, a comprehensive investigation has also been done regarding the factors on which amplitude of partial discharges depend, namely, supply voltage variation, changes in dimension (i.e. size) of void or impurity in the solid dielectric and variation in the number of voids (i.e. an amount of impurity) in the solid dielectric. Finally, a comparative investigation is done using three solid dielectrics which are mainly used in industries, i.e. epoxy resin, dielectric paper, and porcelain. The present work is based on a complete analytical study with the partial discharge model being developed in MATLAB/Simulink using high tension system in the range of 6 kV to 25 kV.
