Partial discharge characteristics of liquid-impregnated laminate dielectric structures
Foil-edge partial discharge phenomena in high energy density, spirally-wound capacitors have been investigated. A partial discharge dependency on V has been found to exist in liquid-impregnated, laminar plastic film dielectric structures. Experiments support the hypothesis that electric charges are injected into the dielectric regions near the foil edge by field-controlled charge injection during impressed voltage transients. The resulting conduction current space charge can establish equilibrium by reduction of the electric field intensity below the partial discharge inception threshold. A temporal characterization of this space charge injection is discussed relative to the effect on partial discharge inception at the foil edge.
