Abstract

This short review deals with some aspects of space charges in solid dielectrics, and in particular in polymeric materials. The relationship between space charges and pre-breakdown events is discussed and the importance of space charges for the breakdown of solid dielectrics is emphasized.

  • Polymers have excellent electrical properties, which render them appropriate for applications in high voltage engineering with applications such as in underground cables, outdoor insulation, switchgrears, capacitors, electrical machines etc

  • Thermal breakdown, electromechanical breakdown, breakdown caused by partial discharges (PD), are some of the proposed mechanisms [13].Efforts have been made in the past to relate space charges and breakdown [4]
