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.
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.
