1、产品概述Summary
    在电网中含有谐波的回路中，若需要改善功率因数而安装电容器时，谐波会导致变压器及电容器产生谐振，为了避免谐振现象的产生可在电容器前串接调谐电抗器，如此可以避免谐振，也可以提高功率因数。
    In the circuit containing harmonics in the power grid, if the power factor needs to be improved and the capacitor is installed, the harmonic will cause resonance of the transformer and capacitor. In order to avoid the resonance phenomenon, the detuning reactor can be connected in series in front of the capacitor, which can avoid resonance and improve the power factor.
