Abstract A method for calibration of electronic transformer test set is proposed. The calibration principle of analog function and digital function of electronic transformer test set is analyzd in detail. And the uncertainty evaluation of the ratio error and phase error of electronic transformer test set is introduced. The proposed method can evaluate the measurement performance of electronic transformer test set as a whole. And the method can be used as a reference for calibration of electronic transformer test set.
