Abstract: In the present work, the fluoro polyimide films were aged in the transformer oil and the characteristic changes in the film and the transformer oil are analyzed through physico-chemical diagnostic studies. The WAXD and FTIR studies showed that no characteristic change in the material due to thermal aging of the material. The FTIR spectra of the corona aged specimen indicate the formation of new functional groups. The fluorescence spectra of the aged transformer oil suggest dissolvement of heavy ions in the clay material.
