电流互感器磁饱和裕度间接测量法的研究

The research on indirect testing method of current transformer saturation margin

在认真分析JJG 1021—2007《电力互感器》检定规程规定的磁饱和裕度测量方法和检定原理的基础上指出了原方法存在的难点,提出了通过间接法测量电流互感器误差和应用传统比较法测量电流互感器误差,结合励磁导纳测试的新方法来测量电流互感器的磁饱和裕度,方法简单,同时保证了测试的准确性。

This paper pointed out the problems existing in the original method based on a careful a-nalysis of verification regulation JJG 1021-2007 power transformer magnetic saturation margin verification method and the verification principle, put forward by the indirect method testing of current transformer er-ror and the application of traditional comparative testing of current transformer error with the new method of the excitation admittance test to test current transformer saturation margin, the method is simple and practical, and ensure the accuracy of testing.
