Harmonic filters are devices used to remove frequency components that are integer multiples of the fundamental frequency from an AC current.
They are used to prevent disturbances caused by harmonics in power systems and industrial equipment. The operating principle involves passing the input harmonic components through a filter with characteristics that suppress them, resulting in the removal of the unwanted AC current. Main applications include substations and power lines in power systems, and drive equipment such as inverters and motors in industrial machinery. The structure of the filter consists of impedances that suppress harmonic components and capacitors that remove harmonics.
Key features include effective removal of harmonic components and improvement of power quality, but it's important to consider the drawbacks of being expensive and requiring maintenance. Accurate measurement of harmonics is required when using them.
