Research on calibration technology for electronic current transformers

In order to improve the stability and reliability of the electronic current transformer, it needs to be tested regularly. The current research status of electronic current transformer testing technology is analyzed in this paper, and the test project of electronic current transformer is introduced. On the basis of analyzing the existing shortages of off-line calibration, an on-line calibration technology of electronic current transformer is proposed in this paper. Test results show that the technology can effectively simplify the calibration process and reduce the cost of the calibration.
