Abstract:

Many different polymeric insulations, such as silicones, epoxies, polyethylenes, etc., are in use. Unfortunately, these materials exhibit decreasing resistance to electrical stress with time. In order to characterize these degradation processes and to suggest materials changes that will ameliorate them, we are developing Fourier transform infrared spectroscopy FTIR techniques to look for molecular changes that occur before breakdown and which may therefore be used as a distant early-warning line for impending breakdown.
