Due to their superior electrical, mechanical, and thermal qualities, polymeric (silicon rubber) insulators are frequently chosen in overhead transmission networks. To increase the dependability of the insulators, it is critical to comprehend the distinct features of such materials. The Comparative Tracking Index (CTI) test is used in the current study to examine the surface characteristics and process of deterioration caused by electrical stress in the presence of contaminants. Because of dry band arcing on the sample's surface, it is discovered that the contaminants have a significant impact on the surface conditions of the material, leading to tracking, degradation, and mass erosion. Additionally, the CTI test is simulated using the COMSOL Multiphysics software, which showed that the concentration of the electric field is increased between the electrodes, which can cause the material to degrade and ultimately fail.
