Abstract In this paper, the error effects of linear interpolation algorithm and parabolic interpo- lation algorithm on the resampling synchronization of electronic transformers are analyzed. A comparative test system is designed for the resampling synchronization algorithm of passive electronic transformer, based on the test data of fiber optical current transformer, the linear interpolation algorithm and the parabola interpolation algorithm are used for resampling synchronization. The results showed that both resampling synchronization algorithms do not affect the noise characteristics of fiber optical current transformer, the parabolic difference algorithm has less influence on the accuracy test results of fiber optical current transformer.
