摘要
The mechanisms of the current peak in the current-time characteristics of PVC containing 1-chloro-2,3-epoxy propane have been discussed. The steady state current is found to be greatly affected by temperature. The current is also found to depend strongly on the environmental moisture. Water ions dissociated under the effect of external field are found to promote the carrier creation and not increase the mobility. These charges are deduced to inherently slowly move and accumulate at the electrodes without discharge rather than be trapped at localized defects, which leads to the appearance of the current peak.
