How Harmonic Filters Enable The Full Utilization Of Power Systems

Nonlinear loads in power systems, such as variable frequency drives and rectifiers, introduce harmonic currents. These harmonic currents cause current waveform distortion, electrical equipment overheating, and reduced system efficiency.

The active harmonic filter cost can design tuned circuits using appropriately sized capacitors and inductors to divert specific harmonic frequencies into low-impedance paths, thereby isolating them from the main grid and power infrastructure.

Filtering out harmonic currents reduces irregular frequency interference in the system, resulting in power output that more closely approximates an ideal sine wave.

Consequently, equipment such as transformers, cables, and motors within the power system can operate stably under design conditions, allowing for more efficient utilization of the system's current-carrying capacity and power supply capability.

After filtering out harmonics, the power factor and voltage waveform quality in the power system recover to near-ideal conditions. This enhances the system's transmission and distribution capacity, significantly improving overall electrical energy transmission and utilization efficiency.
