Characterization and modelling of interface between Epoxy Resin materials and different gases for HVDC GIS cable termination development

Abstract

GIS cable terminations present a complexity of geometry and material assembly that makes their design challenging. The interfaces between materials, and more specifically at the GIS side – that is between the epoxy composite and the gas – are investigated for HVDC application. This study shows dielectric measurements on which modelling of the interface are based and raises the question of gas replacement in such terminations.
