According to the statistics on reliability indices of nation-wide 220 kV and the above power transmission and transformation facilities in 2009, the main influencing causes of scheduled and unscheduled outages were analyzed and evaluated, which affected the reliability of 3 kinds of power transmission and transformation facilities-transformer, circuit breaker and overhead line. Through the analysis of reliability indices in recent years, the changing tendency that affected the main causes of reliability was put forward, which provided the bene-ficial basis for improving the reliability of power transmission and transformation facilities in the coming years.
