Abstract Gage and the component important degree of transmission system reliability can be profoundly reflect information about reliability and system components, use of these information can be found that stifle the weak part of the system reliability, thus providing important guidance for system planning and operation.Deduced in this paper, based on the failure, the failure rate of components important degrees and system power loss index, the index can reflect the elements of full-load operation will affect the reliability of the system. Taking RBTS test system as an example, explain respectively based on the failure and the failure rate of components important degrees of different influence on system reliability, the calculation shows that using the component importance to identify weak part of the system.
