Abstract
The analysis by TSDC of a large variety of cables subjected to long annealing times, has resulted in spectra that sometimes show an oscillation of the current peak observed at 99°C. This process has been observed in some cables only and it is scarcely reproducible. We present an explanation of this behavior based on the formation of charge packets and some other assumptions: charge injection occurs mainly from the negative electrode, and chemical components that act as trapping centers are diff...
