摘要：

The electronic transformer insteads of electro-magnetic transformer is the developing trend. However, it is still difficult to put into practice because the influence of temperature and the stability of long-term operation. In this paper, an electronic current transformer applied in GIS is presented. The mature sensor theory is adopted in order to obtain the steady long-term operation result. And then the testing system of current transformer is designed and realized. The on-site test shows that the error is superior to the standard of 0.2 class transformer. The possible improving measure is discussed at last. This work will be helpful for accumulation of operation experience and improvement of long-term stability.
