5 Industrial Applications Of Active Harmonic Filters

Harmonic distortion in power is an issue plaguing many industries. To combat this, many sectors use active harmonic filters. These filters function by injecting harmonics that are inversely proportional to the distortion present in the circuit. What are some industries and applications that really benefit from an active harmonic filter? This blog covers 5 such industrial applications in detail.

Applications Of Active Harmonic Filters

Welding Plants

Most big welding plant operations use a large amount of electricity. This is mainly due to the process itself, requiring an intense surge of current for a short period of time. This leads to a phenomenon called flicker, causing fluctuations and disturbances in electricity for other facilities in the area. Active harmonic filters help mitigate this and improve equipment reliability.

Renewable Power Systems

Renewable energy sources such as wind and solar are very fickle. They can create a massive surge based on availability, causing problems for the power grid. This is mainly because the grid is not equipped to handle these fluctuations. Active harmonic filters help combat these fluctuations and distortions, reducing the stress placed on the power grid.

UPS Systems

Certain systems are required to run constantly. Known as uninterrupted power supply systems, any malfunction of UPS systems can lead to loss of precious data. To avoid this, active harmonic filters are employed to tackle harmonics and ensure a smooth, stable input current.

Variable Frequency Drives

Variable frequency drives, also known as VFDs or frequency converters, help lower power loss and increase production flexibility. However, they do so at the cost of increasing harmonic emissions. To tackle these harmonics, active harmonic filters can be employed.

Furnaces

Furnaces are known to be some of the most intense operations in modern industry. Thus, they give rise to a lot of harmonic distortion. Using an active harmonic filter here helps to stabilize the production and reduce any negative effects of distortion.
