为准确测量容性设备的介质损耗角，采用小波变换进行低频重构的方法分别求出电压、电流的自相关函数及电压与电流的互相关函数，然后再用相关函数法计算介质损耗角。仿真结果表明：该算法的测量误差曲线基本呈线性，为绝缘介质损耗角提供了科学准确的测量方法。

Aimed at accurately measuring the dielectric loss angle of capacitive equipment, this paper offers the voltage autocorrelation function, the current autocorrelation function, and the cross-correlation function, developed by the low-frequency reconstruction on wavelet transform, together with the cal- culation of the dielectric loss angle through the correlation function. The simulation suggests that this algorithm with the error measuring curve of the basic linearity promises as a reliable scientific method for the measurement of dielectric loss angle
