Electrical degradation and breakdown in polymers
L.A. Dissado,John C. Fothergill +1 more
TL;DR: In this paper, the physical and chemical structure of polymers and their breakdown are discussed, along with the stochastic nature of break-down from empirical and modelling viewpoints, and practical implications and strategies for engineers.
Journal ArticleDOI
Internal charge behaviour of nanocomposites
TL;DR: In this article, the incorporation of 23 nm titanium dioxide nanoparticles into an epoxy matrix to form a nanocomposite structure is described, and it is shown that the use of nanometric particles results in a substantial change in the behavior of the composite, which can be traced to the mitigation of internal charge when a comparison is made with conventional TiO2 fillers.
Journal ArticleDOI
The effect of water absorption on the dielectric properties of epoxy nanocomposites
TL;DR: In this article, the influence of water absorption on the dielectric properties of epoxy resin and epoxy micro-composites and nano composites filled with silica has been studied.
Proceedings ArticleDOI
Towards an understanding of nanometric dielectrics
TL;DR: In this paper, the charge storage and transport of an epoxy resin containing TiO/sub 2/n nanoparticles is investigated, and the results discussed in terms of the underlying physics.
Journal ArticleDOI
Space charge formation and its modified electric field under applied voltage reversal and temperature gradient in XLPE cable
TL;DR: In this article, the results of space charge evolution in cross-linked polyethylene power cables under dc electrical field at a uniform temperature and during external voltage polarity reversal are presented, showing that the mirror effect is a steady state effect that is due to cross-interface currents that depend only on the interface field and not its polarity.
