Research on Three-Phase Calibration Method of HV Three-Phase Combined Transformer and its Implementation

Abstract:

In this paper, a three-phase calibration method which is that the three-phase voltage transformer or current transformer of HV three-phase combined transformer is calibrated in the same time with simulating real running state is proposed. And a standard calibrating apparatus which is used to implementation three-phase calibration method is designed. The structure, working principle, technical characteristics, test circuit and test results of standard calibrating apparatus are given out. The large test results show that the error performance in real running state of 10kV-35kV HV three-phase combined transformer can be calibrated accurately and the error caused by the mutual influence between the voltage transformer or current transformer can be detected out with the proposed three-phase calibration method and apparatus.
