Effect of Temperature on the Output Accuracy of Electronic Current Transformer and Traditional Current Transformer
The temperature variation has certain influence on the measurement accuracy of the coil type electronic current transformer and the traditional current transformer. In this paper, the corresponding relationship between the ambient temperature change and the output measurement accuracy of the current transformer is given by theoretical research. Electronic transformer and traditional current transformer metering characteristics of quantitative comparison test system, through the full temperature cycle test, real-time measurement of electronic current transformer temperature compensation before and after the traditional current transformer at different temperatures in the measurement accuracy, and through the test results to verify the results of this analysis of the correctness and effectiveness.
