Analysis of Mine Low-voltage Leakage Protection in Situation of Great Disparity between Long and Short Lines and Big Unbalanced Current

Analysis of Mine Low-voltage Leakage Protection in Situation of Great Disparity between Long and Short Lines and Big Unbalanced Current

Show other versions (1)

The paper explained that traditional leakage protection principles such as zero-sequence direction relay principle and zero-sequence current's maximum principle are unable to implement selective leakage protection in situation of great disparity between long and short lines and big unbalanced c...
