MODELING THE DIELECTRIC BREAKDOWN STRENGTH AND ENERGY STORAGE DENSITY OF GRAPHITE-POLYMER COMPOSITES WITH DIELECTRIC DAMAGE PROCESS

Modeling the dielectric breakdown strength and energy storage density of graphite-polymer composites with dielectric damage process

Recent experimental data has demonstrated significant influences of graphite volume concentration on the dielectric breakdown and energy storage behavior of graphite-polymer composites, but no existing homogenization theory has been established to illustrate such dependence in the context of alternating current (AC) loading.In this paper we develop

Numerical Simulation for Void Coalescence (Water Treeing) in XLPE Insulation of Submarine Composite Power Cables

Due to the growing demand for offshore renewable energy, the development of durable submarine power cables is critical.Submarine power cables are expected to have a service life of over 20 years.However, it has been shown that these cables suffer from water-tree flaws that progressively extend to conductors and corrode copper, which may berness whi
