The control of the dielectric permittivity and losses of solid insulators, through an understanding of the origin of their dipole relaxation and ionic conduction processes, is essential for their use in electrical insulation. Dielectric Spectroscopy is a powerful tool in the investigation of dipolar and conduction in electrical insulating materials. In particular, the localisation of space charges...
Dielectric spectroscopy is a powerful tool in the investigation of dipolar and conduction in electrical insulating materials. In particular, the localisation of space charges at crystalline - amorphous interfaces in a semicrystalline polymer, such as low density polyethylene LDPE, provides on internal field which could be unfavourable to the insulating properties of the polymer. A physical displacement...
