Tangential continuity [C1 or G1] is the next level, defined by a circular arc creating a relatively smooth transition between these surfaces.

相切(Tangential)连续性[c 1 or g 1]则是下一个层次，指的是建立一个连接这些表面间的平滑的圆弧过渡。

An arc due to an AC signal usually quenches itself as soon as the voltage level passes through zero.

交流(ac)信号产生的电弧通常在电压通过零点时就会自己熄灭。

It was reported that the overvoltage level of low resistance grounding mode is lower than that of arc suppressing coil mode, but the operation carried out the other way.

但经多年的运行，各地普遍认为小电阻接地方式比消弧线圈接地方式的过电压水平要低，但同时反映出的运行状况却存在较大差异。
