Recommended solution: passive filter + active filter.

For all low-voltage systems, configure a capacitor compensation device with filtering function to absorb the main harmonic components in the system; in a heavily polluted low-voltage system, configure a combination of passive filters with different filter coefficients; in key loads, the configuration dynamics Source filter to achieve better governance effect.

Effectively improve the power factor and avoid fines;

Reduce energy consumption and reduce production costs;

Filter out harmonics, ensure the safe and reliable operation of automated production equipment, and improve the operating efficiency of the motor;

Eliminate the hidden danger of system resonance and ensure the safety and reliability of the power supply system;

It can reduce the heat generation of transformers, cables, and motors, increase their service life, extend the mean time between failures of equipment operation, and reduce maintenance, repair and equipment replacement costs.
