摘要
本文论述了研究成功的适合于大型电力变压器局部放电在线监测的电流传感器──非磁性心棒罗戈夫斯基线圈，提出了考虑长传输线影响的等效电路，并在此基础上分析计算了传感器各参数对其频率特性的影响．得出了非磁性心棒罗戈夫斯基线圈的设计方法。
The Rogowski coil with a nonmagnetic core, which is adaptable to on line monitor partial discharge in power transformer,has been studied.The equivalent curcuit that take account of the effect of transmission line has been given.Based on this equivalent curcuit it has been analysed and calculated that the various parameters of current transducer affect on the frequency characteristic and present the design method of Rogowski coil with a nonmagnetic core.
