| Abstract: | 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 calculation 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. |
| Keywords: | dielectric loss angle wavelet transform correlation function algorithm |
