Abstract
Polymeric insulators have shown tremendous growth in their application and are under continuous upgradation since their inception. Insulators undergo several stresses as they are exposed to outer environment and being organic in nature, polymeric insulators degrade because of UV, corona, acid attacks, mechanical and electrical stresses etc. This paper presents the Fourier Transform Infrared (FTIR) spectrum analysis of the failed 220 kV silicone rubber polymeric insulators. The occurrence of different physico-chemical changes in the different shed positions of the failed insulators is studied. The preliminary investigation showed the loss of Alumina Tri Hydrate (ATH) filler from the failed insulator samples. Retention of hydrophobicity have also been reported in the present work.
