Simultaneous space charge and conduction current measurements in solid dielectrics under high dc electric field

, 2006
The importance of space charge in solid dielectrics has been recognized for many years and various attempts have been made to map the distribution and assess its influence on the electrical performance of solid dielectrics. Significant development in non-

Space charge accumulation under the effects of temperature gradient on solid dielectric DC cable

, 2009
It is well known that existence and accumulation of space charge within the insulating material poses threat to the reliability in the operation of dc power cables. When the cables are loaded under high voltage direct current (HVDC), temperature gradient

Evaluation of the onset of space charge and electroluminescence as a marker for cross linked polyethylene ageing [PDF]

, 2001
The aim of the “ARTEMIS” project is to investigate the ageing mechanisms for cross-linked polyethylene under thermo-electrical stress and to identify ageing markers, which can be used to carry out diagnostic procedures.

The influence of physical and chemical linkage on the properties of nanocomposites [PDF]

, 2005
It has been shown by several groups that the mechanical and electrical behavior of composites changes quite substantially, and often beneficially, when the filler particle size is less than 100 nm in diameter.
