摘要
Rogowski线圈是电子式电流互感器重要组成部分,它的设计是互感器精确测量的基础。从数学角度对矩形截面骨架的Rogowski线圈在各种情况下产生的误差进行了分析,提出了一些减小误差的措施。根据改进的措施绕制了新的线圈并对之进行了相关的实验,其设计精度基本达到了0.2级标准,因此对设计精密Rogowski线圈有一定的参考价值。
As a part of ECT, Rogowski coil is the base of precise measurement. This paper analyzes the mathematic model of the errors in many cases and brings forward some improved measures. A new coil is manufactured based on those measures and many experiments are made.The results are according to the standard of band 0.2. So,the improved measures have some value to design the precise Rogowski coil.
