Active Harmonic Filter

---

Neel Industrial Systems Pvt Ltd offers an Active Harmonic Filter.

This offers true harmonics solution:

• Active harmonics compensation
• Improve power quality
• Instantaneous dynamic response
• Flexible up-grading/redundancy
• Various capacity ranges 25 A to 1200 A

Harmonic pollution is an increasing problem that affects all power distribution networks in industrial, commercial, telecom and medical applications.

Most of the power converting equipment or facilities can generate harmonic current:

• Uninterrupted power supply
• DC power systems/chargers frequency converters
• AC/DC variable speed drivers
• Fluorescent lamps
• Welding machines
• Computers and peripherals, etc.

Effects of harmonic pollution:

• Over voltage/current in the distribution network
• Overheated power cables due to skin effect and copper and iron loss in transformers, motors and generators
• Overheating in all types of electronic systems
• Damage to capacitors due to resonance
• Inaccuracy of instrument measurement
• Interference in telecommunication systems
• Voltage distortion and lagging in power factor

AHF behaves like a harmonics current generator. It will measure the harmonics generated from the non-linear loads and cancels these harmonics with a newly generated, opposite phase shifted harmonics current of the same amplitude.

Advantages:

• Eliminates all harmonic currents from nonlinear loads
• Compensates reactive power factor of lagging loads
• Acts as a virtual damping resistor to prevent possible harmonic resonance

Neel AHF is equipped with a user friendly control panel. Neel Industrial Systems Pvt Ltd, since inception in 1979, has concentrated in the field of identifying power quality disturbances and offering techno economic solutions for the past three decades. The company has accumulated rich experience in the field of power quality disturbances and its effects on drives, PLCs and digitally controlled equipment.
