快速检定电流互感器准确度的方法

Fast Method for Calibrating Accuracy of Current Transformer

以往对电流互感器的现场检定通常采用传统的检测手段,只能简单测量出一个变比误差,难以在施工现场进行互感器磁饱和性能的检定。文章提出了选用C43型磁电系直流微安表作为测试元件进行现场测定的方法,该方法能够迅速判断出电流互感器的磁饱和性能,进而实现对电流互感器准确度的快速检定。

The traditional on-site calibration method of current transformer can only obtains the error of transformation ratio and is difficult to examine the magnetic saturation property. In this paper, the on-site detection method by using C43 type magnetoelectricity current microampere meter as the detection component is put forward, which can examine the magnetic saturation property rapidly and further realize fast calibration of the accuracy of current transformer.
