Dielectric characterisation of epoxy nanocomposite with barium titanate fillers

Dielectric characterisation of epoxy nanocomposite with barium titanate fillers

High permittivity materials are currently in use for mitigation of electrical stress in high-voltage apparatus and energy storage systems. In this work, epoxy-based high permittivity nanocomposites with Barium titanate (BaTiO(3)) nanofillers are considered, for the purpose of stress mitigation. Unif...
