摘　　要：在现代电力系统中,Rogowski线圈已被广泛应用于电流测量。但是用于小电流(小于1000A)测量的高精度Rogowski线圈的研制是目前电力系统的一大难题。本文介绍了一种采用新型材料制作的线圈,并且利用后续电路对线圈输出信号进行处理,从而使线圈的精度得到提高。实验表明,在其工作温度范围内线性度非常好,而且其相位差极小,完全满足设计的要求。In modern power system, Rogowski coil has been used to measure current. But the high precise Rogowski coil for the measurement of small current (<1000A) is the most difficult subject in power system. This paper introduced a new coil that adopted new material. And we utilized the circuit to dispose the induced voltage. As a result, the precision of coil can be increased. The experiment indicated that during the temperature range of its work the linearity was very good and phase difference was so small that it meet the requirement of the design also.
