Passive Harmonic Filters

BITCON also offers strudy and economic Passive Harmonic Filter (PHF) Panels. In these panels the harmonic filtering techniques to a large extent are still the most commonly used techniques for current harmonics mitigation of 6-pulse front-end diode rectifier application.

Key Features

  • tuned harmonic filters
  • 6-pulse converters
  • IEEE 519
  • strudy design, long life

Product Application

Industry’s like Automotive Arc Welding Metal Cement Chemicals Pharmaceuticals Textiles Petrochemicals Lifts, Port, Cranes, Pulp and Paper Wind farms & Solar Power Water and Waste Water treatment Crushers and shredders.

Product FEATURES

We have developed an efficient Passive Filter, which are specifically designed to provide superior harmonic filteration (to tolerable levels as defined by IEEE-519 ) as compared to other competing technologies for use in 6-pule front-end diode reectifier applications. Since all filter components are passive (input reactor, output reactor, shunt reactor, capacitor) they are rugged, maintenance free, reliable and low cost. .

It is however impoartant to note that the performance of the Passive Hamronic Filters is dependant on the operating load wrt to the designed load. Lower the loading, lower is the filter performance. Hence the same should be taken into consideration while selecting the optimum rating for a required application.

Product Benefits

  • No active components and hence literally maintainence free operation
  • Harmonics within levels as specificied by IEEE-519
  • Used for a wide range of applications
  • A common PHF can be used for multiple drives working in tandem
  • Highest ROI among comparable filtering technologies available
  • Safe and reliable AC electrical distribution systems
  • Nuisance tripping of protection circuit breakers avoided
  • Improved power quality
  • Increased lifetime of AC distribution system equipment
  • Over-sizing cables, transformers and other AC distribution equipment avoided
  • Improved power factor
  • Lower energy expenses/bills
