Polymer insulators are used in the power transmission and distribution industry as a good substitute to the porcelain and glass insulators. These polymer insulators have many advantages compared to porcelain insulators respectively. Significant improvement has been made in the performance of polymer insulators with continuous evaluation involving its performance and reliability under contaminated conditions for transmission and distribution purposes. This thesis investigates about the performance of polymer insulation under accelerated tracking and erosion test conditions conducted on distribution class polymer equipment’s like composite insulators and polymeric cutouts having a rated voltage of 15 kV. Further electrical tests, additional tests are done for investigating the dielectric strength of composite insulators and polymeric cutouts for studying its degradation process at macroscopic level.
