| Abstract: | This paper analyzes the fundamental principle of the conventional percentage restraint differential protection and the fault component based digital differential protection by using simulation language of MATLAB and SIMULINK.Making use of the simulation language of MATLAB and SIMULINK. It is proved that the fault component based digital differential protection is more sensitive to the faults of transformer. |
