Case studies in the dairy industry highlight that harmonic filters are essential for protecting sensitive equipment from distortions caused by high concentrations of non-linear loads like variable frequency drives (VFDs) and specialized processing machinery.

  • The Problem: Widespread use of frequency converters on production lines caused elevated temperatures and thermal strain on transformers.
  • The Solution: Installation of seven ADF P300 active harmonic filters (ranging from 250A to 450A) in the main switchboards.
  • The Outcome:
    • Voltage Stability: Effectively stabilized the electrical infrastructure.
    • Efficiency: Reduced energy losses and ensured long-term operational stability without disrupting 24/7 production. 
  • The Problem: High peak demand charges and potential harmonic-related equipment damage.
  • The Solution: Installation of Power Factor Correction (PFC) units and Active Harmonic Filters (AHF).
  • The Outcome:
    • Financial Impact: Projected savings of over $660,000 over 10 years.
    • Power Quality: Power factor improved from 0.91/0.93 to 0.99, while AHFs removed harmful harmonics.
