When differential protective relay is applied to transformer protection, how to identify the magnetizing inrush current and short circuit current caused by internal fault is the key problem. Here, regarding the inrush current and short circuit current as the random signal, the sampled data are analyzed by correlation function principle in the digital signal processing (DSP) and the self-correlation...
