摘　　要：在电力系统中,基于Rogowski线圈的电子式电流互感器已被广泛应用于电流测量。本文介绍的互感器采用新型模拟信号处理系统对Rogowski线圈输出的信号进行处理,完成电流的测量和过载保护功能。简化了设计过程、降低生产成本,并且提高了互感器的精度,可达到0·2级要求。In modern power system, hybrid current transformer based on Rogowski coil has been used widely to measure current. This paper designed a new system to dispose the output analog signals of Rogowski coil, so as to fulfill the measurement of small current and over loading protection. So we could predigest design and reduce production cost. Besides we improved the precision and could reach 0.2 level.
