The problem of divergence produced by using line-model to calculate the tension and coefficient of self-inductance of a circular current loop is discussed.

分析讨论了一些文献在计算载流圆环处于自身磁场受的张力和自感系数时使用线电流模型的不当所带来的发散问题。

The Rogowski coil ranged in the same axis was used as current sensor, in which the self-integral resistance should has smaller inductance and smaller capacitance as possible.

电流测量探头采用自积分的罗柯夫斯基线圈，自积分电阻的电感、电容要尽可能的小，并采用同轴结构。

Small size, good self-healing effect, low inductance, low loss at high frequency, strong over-current ability, and can withstand high current impulse.

体积小、自愈性好，电感量低，高频损耗小，过电流能力强，能承受瞬间大电流冲击。
