• Resumen

  • Polymeric insulation is progressively replacing traditional materials in cables, switchgear and machines. The fundamental electricl properties of polymer dielectrics such as conduction and breakdown are strongly influenced by the presence of defect centres (voids and inclusions) and trapped charge. A thorough understanding of the role of trapped charge in the breakdown process is essential if the full potential of these new materials is to be realised.
