摘要
对比分析了电容型电流互感器末屏介损测量三种不同的接线方式,以测量接线的等效电路为基础分析了测量结果产生差异的原因,并进行了试验验证。最后指出一次绕组短接接屏蔽的测量接线能排除外部干扰,测量最为准确。
Three kinds of different end shield dielectric loss measurement methods of capacitive current transformer are compared. The reason of difference between measurement results is explained based on the equivalent diagram, and the theory analysis is verified by test results. Finally, it is indicated that primary winding connected to shield could eliminate the interference, and this measuring method is the most accurate.
