部放電檢測技術可用以檢測電力設備當下的狀況，以預防電力設備因絕緣材料的瑕疵，發生設備故障甚至燒毀。本論文主要目的為根據音射法(Acoustic Emission, AE)檢測技術與本實驗室所設計的音射訊號放大器及自製音射探頭，建構一套具備自動觸發功能、記錄完整波形、局部放電源定位及分析放電波形功能的自動量測分析系統。藉由本系統具備長期記錄局部放電的功能，分析所取得的放電資料，更可利用系統本身多通道之特性找出電力設備局部放電源的大概位置，進而判斷該高壓電力設備是導因於何種故障或瑕疵。

Partial discharge (PD) detection and measurement techniques can be used to detect the current status of electrical equipment to prevent equipment failure or burning caused by defective insulating materials. Based on acoustic emission (AE) method detection technology and AE signal amplifiers designed in our lab, as well as a self-made AE probe, this thesis proposes constructing an automatic measurement and analysis system featuring automatic triggering, full waveform recording, PD source locating, and discharge waveform analysis. Discharge data obtained by the system were analyzed based on the system function of long-term PD recording. In addition, the location of PD source could be estimated using the system’s multi-channel feature to identify the cause of failure or defect in high voltage electrical equipment.
