The research about the intelligent substation electronic transformer ’s error influence and calibration problems
In this paper, we compared electronic transformer, merging unit and communication system in the intelligent substation’s distributed measurement and control system with the tranditional electromagnetic transformer, and analysised the causes of measurement error. By comparing the traditional calibration method of transformer, we presented the new method of calibration and quantity traceability, for the calibration and traceability problem of electronic transformer.
