Relative Importance of Trapping and Extraction in the Simulation of Space Charge Distribution in Polymeric Insulators under DC Potentials

Abstract

Under high DC voltages polymeric insulators tend to accumulate space charge, leading to a deviation from the designed electric field for the system. Consequently local fields may reach high enough values to cause ageing and eventual failure. A particularly dangerous instance is the appearance of heterocharge at one or both electrodes. The origin for such… (More)
