摘　　要：对目前电力系统广泛使用的调匝式消弧线圈测量电容电流的原理进行了说明,建立了混连运行状态下等值电路,并分析了电容电流测量的误差,通过仿真计算,论证该分析的正确性;对混连运行状态下的消弧线圈的电容电流的测量提出了工程上的改进意见。This paper introduces the principle of measuring the current of the capacitance by using the turn type arc suppression coil, which has been widely used in power system. An equivalent circuit is established and the error of capacitance current measurement is analyzed, particularly when the system runs in mixed ground operation. And then the paper proves the correctness of this analysis with simulations. Finally the suggestion about how to improve the measurement of the capacitance current of arc suppression coil in operation state of mixed ground operation is proposed.
