Paper Abstract

Electronic transformers instead of electro-magnetic transformers are the developing trend. But it is still difficult for electronic transformers to put into practice because the influence of temperature and the stability of long-term operation. In this paper, an electronic combined transformer is presented. In order to obtain the steady long-term operation results, the mature sensor design technology is adopted. And then the circuit part of measuring system is designed and realized. The measuring results made in Lab show that the error of circuit part in measuring system is lower than that of 0.5 class transformer. The on-site measurement is processed at last. These testing results and corresponding analysis will be helpful for the improvement of the whole testing system.
