The DC inclined-plane tracking and erosion test and the role of inorganic fillers in silicone rubber for DC insulation / Ghunem, R. A. in IEEE electrical insulation magazine, Vol. 31 N° 1 (Janvier-Février 2015)  

Public ISBD [article]  inIEEE electrical insulation magazine > Vol. 31 N° 1 (Janvier-Février 2015) . - pp. 12 - 21 Titre : The DC inclined-plane tracking and erosion test and the role of inorganic fillers in silicone rubber for DC insulation Type de document : texte imprimé Auteurs : Ghunem, R. A., Auteur ; Jayaram, S. H., Auteur ; Cherney, E. A., Auteur Année de publication : 2015 Article en page(s) : pp. 12 - 21 Note générale : Electrical insulation Langues : Français (fre) Mots-clés : Insulator testing Polymer insulators Silicone rubber insulatorsWear Résumé : The first polymer insulator for AC transmission lines was developed in the late 1950s. This insulator consisted of a flexibilized epoxy resin weathershed cast onto a fiberglass rod, and field trials on a 138-kV line took place in 1959. Insulators failed almost immediately on energization due to severe tracking and erosion of the bisphenol-A epoxy material, which was later, through inclined-plane tests, shown to be inherently unsuitable for use in outdoor insulation [1]. This article describes a study of the DC dry-band arcing mechanism as a foundation for the development of a standard DC inclined-plane test and its employment in the evaluation of silicone-rubber housing composites for outdoor DC insulation.
