Conventional discharge condition detection methods extracting only certain eigenvalue are not suitable for the Micro-EDM due to the high frequency and distortion of voltage wave shape.
常规放电状态检测方法由于仅采用单一的特征量进行状态判别,因此在加工信号频率高、加工波形产生畸变的微细电火花加工中,不再适用。
Partial discharge (PD) on-line detection can timely reflect the degradation degree of power apparatus, thus becoming a useful technique for condition monitoring and failure diagnosis.
局部放电在线检测可以及时反映电力设备绝缘老化情况,是状态监测和故障诊断的重要手段。
