摘要：

Based on the experiment carried out in the lab on several cables in which there are some typical PD models, the relationship between the single acoustic signal generated by the partial discharge and the apparent discharge magnitude in a line frequency cycle are researched. Further more, through the detection system which is combined of the VHF PD detection method and the acoustic emission detection method, the expressions of the relationship between the voltage value, which is gotten directly from the detection system and the apparent discharge magnitude are gotten by the curve fitting method. At the same time, the method of locating the defect manually with the acoustic sensor is introduced simply in the paper.
