Reliability Improvement Strategy for Transformer Zero-Sequence Differential Protection Based on Zero-Sequence Current Amplitude Difference Characteristics

The zero-sequence differential protection of transformer may cause the reliability to decrease or even malfunction due to the fault of current transformer (CT) when dealing with complex inrush current and fault. To solve this problem, a strategy to improve the reliability of transformer zero differe...
