How effective is the low-voltage filter reactor in eliminating harmonics?

Low-voltage filter reactors are commonly used in the process of eliminating harmonic pollution in power systems. However, in practical applications, some users have questioned the effectiveness of these reactors in dealing with harmonic issues.

The low-voltage filtering reactor has the following effects in harmonic control:

1. Harmonic suppression

Principle: The reactor increases the system impedance, thereby hindering the flow of harmonic currents.
Effect: It can effectively suppress characteristic harmonics such as the 5th and 7th harmonics, reducing the interference of harmonics on the equipment.

2. Improve power factor

Principle: The reactor is used in conjunction with the capacitor to compensate for reactive power.
Effect: Enhance power factor, reduce line losses, and improve power supply efficiency.

3. Protecting equipment

Principle: Reduce the damage caused by harmonics to the equipment.
Effect: Extend the lifespan of the equipment and reduce maintenance costs.

4. Enhance system stability

Principle: Reduce voltage fluctuations and flicker caused by harmonics.
Effect: Enhance system stability and improve power supply quality.

5. Reduce losses

Principle: Reduce harmonic current and decrease losses in the lines and transformers.
Effect: Enhance energy utilization efficiency and save electricity costs.
