Present research status and prospect on partial discharge and detecting technique under impulse voltage in SF6 gas insulation

The significance of studying the partial discharge and detecting technique under impulse voltage in SF6 gas insulation was described, the PD research methods and devices, involving oscillating impulse voltage generator, classical insulation fault model and PD detecting methods under impulse voltage was also studied. The research on PD and its detecting technique under impulse voltage in SF6 gas insulation was still in lab, which focused on the PD mechanism and characteristics under impulse voltage in classical insulation fault model （Needle-plane and insulation voids）. At last, the outstanding problems were put forward and the tendency of the research is summarized and forecasted.
