摘要

The effects of 5% wt BaTiO/sub 3/ additive and of electrode material on space charge formation and electric field distribution in low density polyethylene (LDPE) were investigated using a thermal step technique. Space charge was formed at an average dc field of /spl sim/28 kV/mm and at 50/spl deg/C. Results indicate that the addition of BaTiO/sub 3/ to LDPE has considerably reduced the remanent space charge and electric field and changed their distribution patterns in the doped material when compared with the plain material. It is also shown that the remanent space charge and electric field in plain LDPE are strongly dependent on the type of electrode material.
