| 摘 要： | 设计出以罗哥夫斯基线圈为传感器,加有相位比较环节的工频电流测量系统。通过相位比较环节能大为提高测量的相位精度。从试验结果可看出,该系统可还原电流的波形,并能较为准确的测量出工频电流的幅值,平均误差约为1%,相角差不超过20′。

| Abstract: | Industrial frequency current measurement system using Rogowski coil as sensor and adding phase comparison step was designed.Phase precision was greatly improved after adding phase comparison.From the experiment result,the system could revert current wave and precisely measure the amplitude of industrial frequency current.The average error was about 1% and phase-angle error was less than 20'. |

| Keywords: | industrial frequency current Rogowski coil integral implement phase compensation |
