摘　　要：变电站数字化已成为今后电网发展的趋势,电子式互感器是数字化变电站的重要组成部分,也是故障率比较高的部分。针对某数字化变电站的半电子式电流互感器误差检测过程中发现的角差异常问题,通过分体故障排除法,查出角差异常原因,并提出了解决办法,为同类故障分析提供了理论依据。Digitized substation has become the trend of power grid development. Electronic C＇F is an important part of digital substation and also with higher frequency failures. Based on the angle difference abnormal during semielectronic CT error examination, the failure reason has been analyzed and solutions has been proposed, which provides theoretical basis and instructions for the analysis of similar faults and solving practical problems.
