Abstract

EL tests have been performed on specimens which are more representative models of the shield/insulation interfaces in real cables. Significant improvements have been made to the optical and photon counting systems. The importance of the dissolved gases in polymers to electroluminescence processes has been verified. The diffusion of dissolved gases can have a significant influence on the EL characteristics at high temperatures
