Research on Automatic Calibration Technology of Transformation Ratio Tester

With the gradual improvement of the transformation ratio test method and related technologies, the accuracy of the transformation ratio tester has been correspondingly improved, and the requirements for its verification methods are also increasing. Aiming at the problems in the verification of the variable ratio tester, the test principle of the variable ratio tester is analyzed, and an automatic calibration technique is used to realize the automatic calibration of the variable ratio tester. The calculation of the uncertainty is to ensure the accuracy of the test results of the variable ratio tester, but in order to further ensure the accuracy of the test results, it is necessary to conduct a systematic test on the system to verify the accuracy and stability of the system.
