消谐主要是消除二次谐波以及高次谐波，有利于电网的安全运行。 正常运行时，消弧线圈中无电流通过。
Harmonic elimination is mainly to eliminate the second harmonic and higher harmonic, which is conducive to the safe operation of the power grid. Normally, no current passes through the arc suppression coil.
而当电网受到雷击或发生单相电弧性接地时，中性点电位将上升到相电压，这时流经消弧线圈的电感性电流与单相接地的电容性故障电流相互抵消，使故障盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门电流得到补偿，补偿后的残余电流变得很小，不足以维持电弧，从而自行熄灭。这样，就可使接地迅速消除而不致引起过电压。
When the power grid is struck by lightning or single-phase arc grounding, the neutral point potential will rise to the phase voltage. At this time, the inductive current flowing through the arc suppression coil and the capacitive fault current flowing through the single-phase grounding cancel each other, so that the fault current is compensated, and the residual current after compensation becomes very small, which is insufficient to maintain the arc, thus self-supporting. Line out. In this way, the grounding can be eliminated quickly without causing overvoltage
