For manufacturers, harmonic issues often manifest as “nuisance” trips and equipment failures that halt production.

  • The Challenge: A packaging manufacturer faced periodic transformer failures and switchgear fuse blowouts caused by resonance between capacitor banks and non-linear loads.
  • The Solution: Implementing ADF P300 Active Harmonic Filters.
  • The Outcome:
    • Cost Savings: Approximately CAD 30,000 per month saved through eliminated harmonics and corrected power factor.
    • Operational Reliability: Nuisance trips were reduced, and transformers ran significantly cooler, extending their service life.

Summary of Benefits Across Cases

Metric  Before Filter After Filter
Current THD ~18-33% < 5%
Power Factor Low/Penalty levels Near Unity (0.95-1.0)
Energy Savings N/A Up to 12.7% (specific passive cases)
