摘　　要：利用Rogowski线圈外积分回路具有的选频特性,制作了可以测量微小工频泄漏电流的Rogowski线圈传感器。对该传感器做了特性测试和实际泄漏电流的测量实验,结果表明,该传感器抗干扰能力强、测量精度高,能够满足现场测量的需要。Three different current sensors used in the leakage current measurement of high voltage electrical equipments are studied. The Rogowski coil is selected to measure the power frequency leakage current. Based on the behaviors of gogowski coil extemai integration circuit, a Rogowski coil sensor to measure the micro-power frequency leakage current is made. The behaviors of the designed Rogowski coil sensor are tested. The actual ieakage current is measured. The results show that the coil is effective.
