Thereby, fault currents can be distinguished from the inrushes if the improved correlation coefficient between the pre-half and the post-half cycle of the measurand is larger than the setting value.Test results show that all types of internal faults even accompanied by magnetizing inrush can be correctly identified from the inrush with the proposed algorithm. Besides with high reliability , this scheme has satisfying sensitivity.
