摘要
介绍了变压器声电联合PD定位方法基础上,基于1个电信号传感器和2个超声波(AE)传感器进行两个步骤采集波形信号的时延估计,就能对PD源空间坐标解析解求解,表明该定位方法精度满足工程应用要求。
Based on the method of transformer combined acoustic and electrical PD positioning,the time delay estimation of waveform signals acquired in two steps is carried out based on one electrical signal sensor and two ultrasonic(AE)sensors,and the analytical solution of spatial coordinates of PD source can be solved,which indicates that the accuracy of the positioning method meets the requirements of engineering application.
