Effect of DC Pre-stress on Space Charge and Electrical Tree in XLPE with Needle-Plate Electrodes
Space charge is one of the main factors that affect the electrical tree characteristics of HVDC cable insulation. Based on the bipolar charge transport model, this paper simulates the space charge distribution characteristics of the two-dimensional needle plate electrode model under ±20 kV、±22.5 kV...
