IEEE Harmonic & Sinewave Filters

Industrial machinery – such as Variable Frequency Drives, transformers, inverters, furnaces and motors – can generate harmonic frequencies that overburden power cables and circuits, and cause interference with computers, telephones and advanced equipment. CanLift Technologies manufactures and integrates advanced harmonic filtering systems that mitigate distortion and harmonic resonance issues, which occur in power distribution systems and environments, such as:

  • Oil and gas
  • Industrial
  • Wastewater treatment plants
  • Commercial buildings
  • Hospitals
  • Airports

Benefits of the Product

  • Eliminates tripping and exceeding of voltage peak
  • Minimizes noise pollution
  • Decreases vibration and mechanical stree
  • Prevents overheating in power grids
  • Reduces aging of system
  • Reduces interference with electronics
  • Improves power factor and saves money
  • Cost-effective solution to meet IEEE-519 requirements
  • Can operate in harsh terrain and extreme temperatures
  • Easy access inside the enclosure
