摘要
分析了现有便携式互感器现场测试仪的基本原理,通过与传统电流比差法进行电流互感器试验对比分析,试验数据指出了其对GIS穿心式SF6绝缘电流互感器的不适用性,并分析其原因.
The basic principles of the existing portable transformer calibrator are analyzed. Through the comparison and analysis of current transformer error test between the portable transformer calibrator and the traditional one, the test data indicate that it is not suitable for straight -through current transformer in GIS, and the reasons are analyzed.
