Partial discharge detection under impulse voltage is an effective method for monitoring the insulating properties and the aging of high-voltage electric equipment. It is of great practical significance for discovering potential safety hazard in time and ensuring the safe operation of equipment. In this paper, we set up an impulse voltage source with solid-state switch, the discharge signals of needle plate electrode in the oil are detected by using the photomultiplier. The results show that the measurement can successfully detect the discharge signal both in the wave head and the wave tail, the signals in the wave head usually have a long duration, intensely and constantly discharge; the signals in the wave tail usually have a short duration, weakly and discontinuity discharge. We make the analysis with a possible mechanism of physical aiming at this phenomenon.
