Electronic transformers and merging units are the core components of smart substation. The performance and accuracy of these indicators have a decisive impact on the following measures: protection, measurement and control, and digital energy metering. However, selection or acceptance, regular testing and other aspects of the measures taken or means have not yet reached a perfect, comprehensive and accurate level. This paper presents a merging unit tester traceability device with table source integrated separable structure characteristics, both for electronic transformer calibrator and the merging unit tester traceability. It can also directly calibrate the electronic transformer and the merging unit error.
