摘要
为测量陡脉冲小信号,经磁芯选择、参数优化研制了一种罗科夫斯基线圈宽带微电流传感器。测试表明其线性度好、回差变化小、阶跃响应时间快,带宽396 kHz^120 MHz,灵敏度3.27 V/A,适于陡脉冲小信号测量。
A wide band low current transducer is investigated on the basis of Rogowski coil. By selecting magnetic cores and optimizing chief parameters, the current transducer is developed with characteristics of a frequency bandwidth of 396-120MHz and a sensitivity of 3. 27VIA. The test results show the transducer is characterized by a fast step response, good linearity and small changes on delay.
