| Abstract: |
| The cause of the incorrect trip of line Bei Da is analyzed.The over high setting of surplus of receiving signal level may introduce maloperation of high frequency protection,which is normally neglected by protection engineers.The suggest for soling this problem is proposed. |
| Key words: surplus of single-receiving,high-frequency protection,wrong action, |
