摘要：

Water treeing is one of the most common failure modes of XLPE cables. The dielectrophoresis force acting on micropores in XLPE has been identified as a proponent of water tree growth. This paper explores the effect of micropore size, relative position and frequency on dielectrophoresis force using ANSYS simulation studies. When the defect size increases the stress induced by dielectrophoresis force shows a decreasing trend. When the void is closer to the cable shield, the dielectrophoresis force increases. The dielectrophoresis force in the 1mHz similar to 1Hz frequency range is comparatively high, and the stress induces in the higher frequency range shows no change. The dielectrophoresis force-induced at a very low frequency (VLF) is higher than in the nominal operating frequency of XLPE.
