Abstract
In this paper
the actural measurement on-site and numeric calculating method are described.The DC current distribution in ground and its harm to the AC system during monoploar ground return are analyzed.Based on the study and analysis
an effective measure that could restrain the current through transformer neutral point is proposed.
