In grid, nonlinear loads, such as diode rectifiers, will release a large number of harmonics into the power grid during operation. The harmonics appear in the form of reactive power on the power grid, which not only cause a lot of heat in the transformer to seriously affect the capacity of the transformer, but also flow into other loads and affect their proper operation. To effectively suppress the harmonics, a corresponding APF device must be deployed on the load side.
