摘要:
介绍一种利用空间电磁波信号对电力设备进行绝缘诊断的在线方法.系统由两方面组成,其一是空间电磁波时间差法,另一个是信号的时间-频率分析.试验的结果表明,此项技术对GIS的绝缘状况进行自动监测是可能的.
Abstract:
A new on-line insulation diagnostic technique for the power apparatus by detecting electromagnetic signals emitted form PD is presented in the paper.This technique consists of two methods,one is Time Difference Method and the other is Time-Friquency Analysis Method.This technique is show to be usuful and progressive for detecting the symptom of the insulation fault.
