500 kV H-GIS站电流互感器误差异常的分析及意义
Analysis of Abnormal Error of the Current Transformers in 500 kV H-GIS Substation
【摘要】 用传统的测试方法对两个H-GIS 500 kV站电流互感器进行了现场误差试验,试验发现电流互感器的误差存在异常,分析了用推算方法对这类电流互感器进行现场误差试验的局限性,同时给出了这个事件所带来的意义。
【Abstract】 The field error tests of the current transformers in two 500 kV H-GIS substations were conducted with the conventional method,and the results showed that the errors were abnormal.The limitation of the method for testing the error of this king of current transformers is analyzed.
