其本质是一种高容量非线性电阻器，起阻尼与限流的作用。可以起到良好的限制电压互感器铁磁谐振的效果。 如果6～35kV电网中性点不接地，母线上Y0接线的PT一次绕组，成为该电网对地唯一金属性通道。电网对地电容通过PT一次绕组有一个充放电的过渡过程。试验测得此时常常有最高幅值达数安培的工频半波涌流通过PT，此电流有可能将PT高压熔丝熔断。而安装了消谐器后，这种涌流将得到有效抑制，高压熔丝不再因为这种涌流而熔断。

Its essence is a high capacity nonlinear resistor, which is the function of damping and limiting flow. It can be effective to limit the effect of ferromagnetic resonance of voltage transformer. If the neutral point is not grounded in the 6 ~ 35kV grid, the PT winding of Y0 on the bus line becomes the only gold channel for the grid. The electric grid has a transient process of charging and discharging through the PT winding. The test results show that at this time, the highest number of amperes with the highest number of amperes are flowing through PT, and the current is likely to fuse the PT high pressure fuse. When the dissonant is installed, the flow will be effectively suppressed, and the high pressure fuse will no longer fuse because of this flow.
