Energy Safe Electric active harmonic filter overview

Overview

Modern electrical installations containing variable speed drives (VSDs), UPS systems, EV chargers, LED lighting and other non-linear loads generate harmonic distortion that can reduce equipment life, increase energy losses and cause compliance issues. Active Harmonic Filters (AHFs) provide a real-time solution by continuously monitoring the electrical network and injecting equal and opposite currents to cancel unwanted harmonics.

Key Benefits

  • Reduces current harmonics and improves power quality
  • Extends the life of transformers, cables and electrical equipment
  • Lowers overheating and nuisance tripping
  • Improves power factor and system efficiency
  • Balances three-phase loads and reduces neutral currents
  • Assists compliance with Australian power quality requirements
  • Modular, scalable design for new and existing installations

Typical Applications

  • Commercial buildings
  • Manufacturing facilities
  • Data centres
  • Hospitals
  • Water treatment plants
  • Mining operations
  • EV charging infrastructure
  • Industrial process plants
