PD pulse phase distribution spectrum was compared with spectrum, and 95% fiducial intervals of statistic operators were also summed up.
比较了局部放电的脉冲相位分布谱图和谱图的差异,并计算了各类放电对应的统计算子95%置信区间。
The operator can see (and capture) video and still photos on the hand held controller as the operator sends the PD-100 up to a kilometer away.
当PD-100控制到1千米以外时,操作员可以在手持控制器上看到(和捕捉到)视频及图片。
PD signal is weak signal, so the first problem of on-line monitoring is how to pick up the weak anti-stationary random signal.
由于局放信号属于弱脉冲信号,因此实现在线监测的首要问题是如何从强干扰中提取弱的非平稳随机信号。
