The study of the effect of space charge within dielectric materials is important with respect to understanding the mechanisms of aging and breakdown. Accumulation of space charge in insulation can accelerate degradation through local field enhancement, and consequent ionisation/excitation and electromechanical energy storage. Aging and breakdown of the polymers are related to the release of the electromechanical energy around trapped charges. In this work, space charge mapping and conduction… CONTINUE READING
