温度对电子式电流互感器与传统电流互感器输出精度的影响
Effect of temperature on the output accuracy of electronic current transformer and traditional current transformer
摘要
Abstract
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.The metering characteristics of quantitative comparison test system of electronic transformer and traditional current transformer is utilized to test the real-time measurement accuracy between the electronic current transformer temperature compensation before and after and the traditional current transformer at different temperatures through the full temperature cycle test.The correctness and effectiveness of the analysis result are verified through the test results.关键词
