IPC: G01R29/00
Filed: 1990-03-22
Abstract: PURPOSE:To facilitate estimation of an input elastic wave caused by a partial discharge by a construction wherein an absorbing body matched acoustically with a piezoelectric element constituting an AE sensor is fitted on the detecting surface side of th piezoelectric element with a second electrode interposed therebetween. CONSTITUTION:An elastic wave 51 generated with a partial discharge of a sample 11 is inputted to a piezoelectric element 21 through an input electrode 28 and a first electrode 22. The elastic wave inputted to the piezoelectric element 21 is converted into a voltage signal in the piezoelectric element 21 and taken outside as a detection signal through a takeout electrode 25 and a lead wire 31. The elastic wave reaching a second electrode 23 is inputted, without being reflected, to an absorbing body 24 matched acoustically with the piezoelectric element and it is attenuated in the absorbing body 24. Since the elastic wave is not reflected, but absorbed by the absorbing body according to this sensor, the detection signal obtained is free from the effect of a reflected wave and reflects the waveform of the elastic wave with excellent fidelity.
