| 摘 要： | A big operational problem of high voltage (HV)power equipments is the degradation of the insulation,to which partial discharge (PD) is a major contribu-tion. Currently, the main collectingtechniques for PDsignals include the electrical pulse associated withPD, the electromagnetic waves detection method andthe acoustic detection method. PD generates acousticwaves, which can be used to detect the intensity andlocation of the PD. Compared with the detectionmethods, the acoustic methods have a…
