摘要
在局部放电在线监测中，对强大的通讯干扰的抑制效果直接关系到内卦部放电的鉴别和内部放电类型的识别等后续工作．本文中首次将一种基于MAXNET横向抑制作用的数字滤波技术应用于局部放电信号处理中，通过仿真实验和现场数据的分析处理，阐明了它在局部放电在线监测中对于通讯干扰是一种行之有效的新数字滤波技术．
During on-site PD measurements, the rejection result of strong communication interference is closely related to not only the identification of interinal and extemal discharges, but also to the recognition of different internaldischarges. In this paper, a new digital filtering technique based on the transversal inhibition effect of MAXNET areproposed for the first time. The simulation experiment and the digital signal processing of spot signals, prove thatthis method is effective for on-site PD measurements.
