Preventing Space Charge Accumulation by Incorporating Electrets
Advanced Materials Interfaces, 2023 Space charge accumulates near electrodes in insulating materials under high voltage direct current. Electric stress created by charge accumulation distorts electric field, reduces the remaining useful life of insulating materials, and decreases partial ...

Space Charge Accumulation Characteristics in HVDC Cable under Temperature Gradient [PDF]
Energies, 2020 One of the main issues that affect the development of high-voltage direct-current (HVDC) cable insulation is the accumulation of space charge. The load operation of an HVDC cable leads to the formation of a radially distributed temperature gradient (TG ...

The influence of electrodes and conditioning on space charge accumulation in XLPE [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2000 The accumulation of space charge in planar crosslinked polyethylene (XLPE) samples under dc electric fields at room temperature was investigated using the pulsed electroacoustic (PEA) method. Three different organic semiconductor (semicon) materials containing carbon black at concentrations /spl sim/30 %wt, and vacuum-evaporated gold, were used as ...
