The dependence of space charge trapping threshold on temperature in polymeric DC cables was discussed. The charge detrapping rate followed an Arrhenius-type law when the poling electric field was large enough to cause copius injection of electrons to dominate transport and trapping process. The ionic and electronic charge carriers were taken into account by the conduction mechanism at fields close to charge accumulation threshold. The threshold field was found to decrease significantly with the temperature increment.

Abstract
The dependence of space charge trapping threshold on temperature in polymeric DC cables was discussed. The charge detrapping rate followed an Arrhenius-type law when the poling electric field was large enough to cause copius injection of electrons to dominate transport and trapping process. The ionic and electronic charge carriers were taken into account by the conduction mechanism at fields close to charge accumulation threshold. The threshold field was found to decrease significantly with the temperature increment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
