Fast charge packet dynamics in XLPE insulated cable models

Résumé

This paper deals with the investigation of space charge accumulation dynamics in XLPE electrical insulation. In particular, very fast charge packets, i.e., having large mobility, are observed to be injected from both electrodes and to cross the insulation bulk, thereby contributing to heterocharge build-up at the opposing electrodes after just a few seconds from the beginning of polarization. The mobility of these charges, depending significantly on temperature, is estimated through observation of charge packets as a function of time.
