| Abstract: | The old calibration technology of transformers has not satisfied with the performance test of electronic current transformers. According to the output characteristics of electronic current transformers(analog voltage signals and digital signals), the theory and method of calibration technology for electronic current transformers are discussed in this paper based on the standard of IEC60044-8. The virtual instrument technology is introduced, and the calibration system of current transformers is constructed, combining with the designed hybrid optical current transformer. The test results of ratio error and phase error are given and analyzed. |
