As its operation reliability can reflect the operation status of equipment in real time, the optical DC current transformer is widely used. Based on the synthetic probability method, this paper studies the relationship between the common state quantities pointing to different defects of different components and their operating states. This paper focuses on how to calculate the operation reliability of the optical CT when multiple state quantities point to the same defect from different principles. The case shows that the operation reliability of the optical CT obtained by this method is similar to the empirical results of many experts, which shows the effectiveness of this method and provides a new idea for the research of the operation reliability of the DC optical CT.
