초록
It is very essential to find out defects and remove them in the insulation at the early stage because the defects in the insulation induce PD which deteriorates the material, resulting in the breakdown. In the real application of high voltage, the interface of the different insulation is the weakest place for both electrical and mechanical aspects. In this paper, characteristics of PD caused by the artificial defects, such as metallic particles, voids and moist fibers, at the interfaces of the cable joint (PJB) were investigated using the specially designed electrode system.
