Abstract :
This paper deals with a polymer quite new in the domain of electrical insulation and its behaviour under corona discharge activity. Results on the stability of discharge regime, achieved during two hours of experiments, under three different temperatures are presented for poly(ethylene-2,6 naphthalate) (PEN). An FTIR analysis gives the evolution of the polymer structure and the bulk conductivity measurements reveal the threshold of electrical properties modifications, likely related to trapped charges. It is found that PEN is more sensitive to temperature than to chemical modification due to discharge species
