sound phase meaning in Chinese

健全相

Through research on principle and approach , this paper puts forward three new methods in power cable fault location . the first method is based on wavelet reconstruction , and the measured signal which is the difference between the faulty and sound phase current under the high voltage pulse excitation , is transformed using wavelet , and the high frequency component is reconstructed at single scale
基于小波重构的电缆故障测距方法采用脉冲电源作用下故障相与健全相的电流差作为测量信号，利用小波变换对其作多尺度分解，然后对信号在高频下进行单支重构。
The methods above have been simulated using emtp and matlab , and the simulation results indicate that , ( 1 ) in the fault location method based on wavelet reconstruction , the influences of reflected waves from tee joints or resistance discontinuities except the fault point can be eliminated when the current difference between faulty phase and sound phase is used in fault location
本文利用emtp和matlab程序对上述方法进行了数值仿真，结果表明： ( 1 )在本文所提出的基于小波重构的电缆故障测距方法中，利用健全相和故障相的电流差信号进行故障定位，能消除故障点之外其他阻抗不匹配点的反射波的影响。
