| Abstract: | Aiming at a misoperation accident of relay protection devices in 750 kV power transmis?sion line, analyzes the cause of accident, combining locale actual condition, puts forward preventionmeasures. The result shows that mastery the principle of the communicated three-phase trip loopand the diversificational realization means of its function is an important approach to avoid suchaccident. |
