So that the maximum pd grads is the characteristic quantity of evaluating the insulation condition of stator bar has been put forward 因此，提出了以绝缘局部放电的最大放电量的梯度作为评定绝缘的一个特征量。
On - line pd monitoring of power transformer is presently the research hotspot in the area of high voltage insulation measurement and diagnosis 变压器局部放电在线监测是高电压绝缘检测与诊断领域研究的热点课题。
This paper investigates a new method of extracting partial discharge signals of hydroelectric generating set based on empirical mode decomposition ( emd ) 摘要提出一种基于经验模态分解( emd )的水轮发电机组局部放电信号提取方法。
Due to the weakness of pd signals and bigness of interferences , the extraction of pd pulses faces many difficulties 由于实际产生于变压器内部的局部放电信号非常微弱，加上现场严重的电磁干扰，局部放电信号的在线获取困难很大。
The detecting system can monitor pd online , reject noises , analyze pd faults , and show the finger prints of the detected pd 此系统可在实验室正确运行，可以对放电进行监测、从干扰中提取局部放电脉冲、统计分析放电类型并绘制出统计谱图。
