Abstract :
Focused on the analysis of some parameters derived from PEA measurements, the article tries to identify the evolution of space charge and field in thermally aged paper-oil systems, and to emphasize, by comparing to unaged structures, some aspects susceptible to lead to a higher reliability of DC cables insulation.
