| Abstract: |
| The operating conditions of line main protections(lognitudinal affiliation,distance,zero sequence,recloser)and microprocessor based protections for 220 kV and above systems in 2000 are introduced,and the occurred misoperations are analyzed.It is to prevent the similar faults and improve the operating level by exchanging the experience and learning the lessons. |
| Key words: line protection,operating condition,analysis, |
