摘　　要：指出测量变压器套管的介质损耗因数tanδ中非同步采样是引起测量误差的关键因素,分析了采样率、信号的谐波分量和采样初始相位在非同步采样时对测量结果的影响程度。It＇s pointed out that the key factor to bring about measurement, error is the non-synchronous sampling in the tanδ measurement of the bushing in a transformer. The influences of the sampling rate, the signal harmonic component and the sampling initial phase to the measuring results are analyzed..
