电流互感器复合误差试验方法研究

Study on Measuring Composite Error of Current Transformer

研究电流互感器在短路故障时误差性能,需提高其复合误差试验能力与测量活动质量。在分析了电流互感器误差与现行试验方法后,介绍了使用Rogowski线圈为传递标准,采用"即校即用"技术的试验方法,为大电流现场量传提出一种实用的新方法。

In order to study the error performance of current transformer （CT） in short-circuit fault conditions, it is necessary to improve the composite error test ability and the measuring quality. After research CT error and traditional test methods, use Rogowski-coil as transfer standard is introduced, the ＂immediately measure after calibration＂ application technology is adopted, and a new practical method is presented for high current field calibrationt.
