The HFL series includes various models with different reactive power ratings and conductor materials:

•  HFL 7/x Cu: Copper conductor filters with a 7% detuning factor
  • .Available in ratings from 5 kVAr to 100 kVAr.
• HFL 14/x Cu: Copper conductor filters with a 14% detuning factor. 
  • Available in ratings from 5 kVAr to 50 kVAr.
• HFL 7/x Al: Aluminum conductor filters with a 7% detuning factor. 
  • Available in ratings from 20 kVAr to 50 kVAr.
• HFL 14/x Al: Aluminum conductor filters with a 14% detuning factor. 
  • Available in ratings from 20 kVAr to 50 kVAr.

Note: The 'x' in the product type represents the reactive power rating of the filter in kVAr.

The selection of the correct filter is based on several factors such as the type of load, the level of harmonic distortion, and the required compensation. The provided tables in the sources can be used as a reference for selecting the appropriate filter.

• 7% detuning filters are generally used in networks with a high presence of the 5th harmonic and higher.
• 14% detuning filters are suitable for networks with a high presence of the 3rd harmonic.

• Filters should be installed in series with the capacitors to create a tuned circuit.
• Ensure proper ventilation around the filters to prevent overheating.
• Refer to the mechanical dimension charts for proper mounting and installation.
