In pulsed power systems, pulsed currents with risetimes from nanosecond to microsecond can be effectively measured by self-integrating Rogowski coils. Appropriate design of the structure and the integrating resistor is crucial to the high-frequency response of a coil. In this paper, several novel designs of Rogowski coil's integrating resistors were proposed and tested. Experimental results showed that the optimized coil could response square waves with fronts of ∼1.5 ns and had a sensitivity of ∼0.75 V/kA. The maximal peak current was designed as 100 kA.
在脉冲功率系统中，自积分式罗戈夫斯基线圈能够有效地测量上升时间从纳秒到微秒的脉冲电流。罗戈夫斯基线圈结构和积分电阻的合理设计对于线圈的高频响应至关重要。本文提出并测试了几种罗戈夫斯基线圈积分电阻的新颖设计。实验结果表明，优化后的线圈能够响应前沿约为1.5纳秒的方波，灵敏度约为0.75伏/千安。最大峰值电流设计为100千安。
