摘要 分析了水轮发电机局部放电在线监测系统中的现场干扰信号特点及超高频检测技术和脉冲时延鉴别法现场抗干扰的原理 。 Field noise in the on line partial discharge measurement system of hydro generator is analyzed. The EHV measurement techniques and pulse time delay identification are used to reject the field noise. They are effective not only in the laboratory but also in the field.
