Harmonic Filters

ACTIVE HARMONIC FILTER (AHF) Suppliers in Chennai,Tamil Nadu, India

Active Harmonic Filter can realize 2nd to 50th harmonic compensation, compensation ratio can be set selectively by the customers, output compensation current follows the system harmonic variation, devoted to green power quality. AHF is an equipment to mitigate harmonic and. The IEEE 519 compliance (a guideline for limiting harmonics) in a power system is more and more compulsory.

• Can offer precise rating to the specific AHF rating requirement. Anyone of above rating can be connected in parallel with another rating to have precise Filter rating.
• Products are compact in size, occupies less space.
• Products are with 3 Level IGBT Topology- Less watt loss (Less power consumption)
• AHF has inbuilt Over current /Short Circuit Current Protection.
• Can respond higher current requirement in compact cabinet.

EMERSON AF3 - Three phase State-of-the-Art active filter, that dynamically cleans up Harmonics and improves Power Factor, for all types of electrical installations. It has dynamic control features and has no resonance effects, no reactive power circulation, no passive components.

Harmonics are the by-products of Modern facilities and Electronic equipment. These are often called non-linear loads, such loads are:

• Servers, Computers, PCs, Printers and other IT Equipment (Having Switch Mode Power Supplies)
• Controlled Rectifiers, Battery Chargers, Uninterrupted Power Supply (UPS) systems
• Phase controlled AC voltage regulators
• Compact Fluorescent Lamps, Fan regulators
• Traction Equipment
• Arc Furnaces or Induction Furnaces, Welding Machines
• Adjustable Speed AC and DC Variable speed motor drives
• PLC, DCS and SCADA systems (SMPS)
• Solid State Heater Controls
• HVDC sending and receiving end equipment

Passive Harmonic Filter is designed to maintain the Power Factor with the Harmonic Mitigation. Power factor correction in systems where harmonics are generated by nonlinear loads, each step of detuned filters consists of a capacitor and a series reactor connected in series. These two from a series resonant circuit tuned at a frequency below the lowest harmonics frequency present in the system normally the 5th (250Hz). The detuned filter also removes lower order harmonics from the system to some extent. This will help to offset the Resonance effect for longer trouble-free operation.

• We are the leading manufacturer of Detuned Capacitors Panels ( APFC ) in Chennai.
• We do provide sales & Service support for other make Power Factor Panels too.

SinE-Series Active Harmonic Filter, operates on the base of a three -level topology circuit, provide power quality solutions such as eliminate harmonic, stepless power factor correction, and load balance. The AHF module capacity of AHF modular from 15A to 150A, and allows 20 modules to connect parallel, and users can easily get the target filter current capacity.

Product value:
Eliminate the harmonic current of nonlinear load «Improve the operating efficiency of the power system and reduce the downtime of the power distribution system, especially for low-voltage systems with frequent load upgrades Meet the strict requirements of Utilities for electrical energy quality, avoid fines and power supply interruptions caused by electrical quality problems, and reduce carbon dioxideemissions
