Abstract EN
Magnetizing inrush current can lead to the maloperation of transformer differential protection.
To overcome such an issue, a method is proposed to distinguish inrush current from inner fault current based on box dimension.
According to the fundamental difference in waveform between the two, the algorithm can extract the three-phase current and calculate its box dimensions.
If the box dimension value is smaller than the setting value, it is the inrush current; otherwise, it is inner fault current.
Using PSACD and MATLAB, the simulation has been performed to prove the efficiency reliability of the presented algorithm in distinguishing inrush current and fault current.
