| Abstract: | Aiming at the problems of influencing the normal operation of the differential protection device for transformers, the magnetizing inrush current and internal fault current are analyzed and identified by using the principle of dead angle. A single chip microcomputer 80C196KC and double terminal ports memory etc. digital devices are adopted to carry out the microcomputer differential protection with magnetizing inrush current latching for transformers. |
