Abstract
The accumulation of space charge in solid dielectrics is examined from the macroscopic point of view using electromagnetic field theory. For practical dielectrics, it is shown that the occurrence of such charges is an inherent consequence of a non-uniform conductivity. The influence of both temperature and electric field strength upon this space charge formation is elucidated. Thereafter the theory is applied to DC cables
