Detuned Filter:
Detuned filter are used, in supply networks having a high level of harmonic distortion, when the final objective is reactive power compensation at the fundamental frequency. Their purpose is to avoid the harmonic currents overload to the capacitors by diverting them to the mains. Protection filters are made by connecting reactors in series with capacitors, in such a way that the tuning frequency of the whole unit is set at a value between the fundamental frequency and the frequency of the lowest present harmonics, which is usually the 5th order harmonic. In this the filter has a high inductive impedance for all the harmonic frequencies.
Connection of a reactor in series with a power capacitor, makes the capacitor to work at a voltage higher than the supply voltage. Because of this, capacitors need to be connected to protection reactors and need to be designed to work at higher voltages than standard capacitors. The choice of the tuning point of the filters is more...
The Active Filter offered by us is an innovative device for the compensation of current harmonics generated by industrial loads and for power factor correction. Its high filtering perfomance combined with the easyness & simplicity of connection make it the best choice for any problem of harmonics.
A few of the salient features of Active Filters are:

AB Lifasa supply Automatic Detuned filter banks for installation having high levels of harmonic distortion.
These banks are completely assembled and ready for use like Automatic control capacitor bank as explained above.
The low cost, iron core, highly linear reactors of suitable ratings are provided in series with each capacitor unit.
The tuning frequency of the whole unit is set at a value between the fundamental frequency and the frequency of the lowest present harmonics.
AB Lifasa provides a wide range of ratings upto 3000 kva, 440V with tuning frequency of 189 Hz. Other voltage and tuning frequencies are also available on request.
Product Features:
For real - time compensation of harmonic current and reactive power. There are several electrical equipment with non-linear voltage-current characteristics connected to the network. Harmonic currents produced by this cause harmonic voltages in network impedance, which add to the fundamental system voltage resulting in voltage distortion.

Desciption:
In installations with 3rd harmonic generation loads, the current through the neutral cable can be higher than the one in the phases, even in case of balanced loads.
The most proper solution for these problems is to use a specific equipment for the 3rd harmonic filtering, consisting basically in a three-phase isolating transformer, delta-star connected, that filters the 3rd harmonic current, plus a passive filter which reduces the 5th harmonic.
Harmonics are sinusoidal wave forms. They have frequency in multiples of fundamental frequency. They are produced by equipment using frequency conversion technology. They are also generated due to power drawing pattern of non- linker loads.

We manufacture and provide harmonic filters which as the name imply filters harmonic waves. Harmonics are sinusoidal wave forms with frequency multiples of fundamental frequency. Such frequency is formed by equipment using frequency conversion technology and also due to power drawing pattern of non- linker loads. Some sources of harmonic filters include the following: more...
We are trusted name in manufacturing and supplying qualitative harmonic filters. Our product is basically used for saving power. Further, these filters comprise certain feature which have made us preferred company to work with. Following are their features: more...
We offer harmonic filters which are widely used for personal
computers. As PCs use non-linear current which is not in linear relation with
voltage applied. When a sinusoidal voltage is applied, an ideal linear load
should draw sinusoidal current. PC draws current for a very short period during
every half cycle.
Due to harmonics utility of the power source is reduced, lot
of power is wasted and problems like neutral over heating, high neutral to
ground voltage, nuisance operation of trip circuits and harmonic interference arises.
A good harmonic filter reduces the harmonics to less than 5% and overcomes all
the problems related to it. Some of the advantages of our active harmonic filters include the following:

During the last years there has been a large modernization of the industrial production processes and a fast evolution in power electronics, especially in the field of power converters such as variable speed drives for DC motors, frequency converters, UPS. All these equipments have a common characteristic which is the generation of harmonics currents that reduce the quality of the electrical energy.
NAAC completes its range of filtering inductors with a range of electromagnetic harmonic eliminating devices named Harmonic Filter System. The functioning of these devices is based on the cancellation and compensation of magnetic fluxes. The main advantage of the Industrial Harmonic Filters in the absence of electronic components and capacitors. Industtrial Harmonic Filter are therefor maintenance free, have an extremely long lifetime compared with other types of filters and are compatible with any electrical installation.

Medium Voltage Harmonic Filters
Modern electrical equipment demands Power Quality, which imposes stringent demands on voltage stability and power quality. The power network has to be free from harmonics and other electrical disturbances. Multiple Frequency Currents and Voltages existing in the Power System, which are integral multiples of fundamental 50 Hz waveform, are called Harmonics, or “dirty power”. Odd positive and negative sequence harmonic currents, are generated by three-phase full wave, non-linear loads, which are connected to a three-phase, three or four-wire distribution system. Odd positive, negative and zero sequence harmonic currents are generated by single-phase, full-wave non-linear loads which are connected phase to neutral in a three phase, four wire distribution system. Harmonic Currents produce Harmonic Voltage distortion also depending on system impedance. The major contributors of Dirty power (Harmonics) are: more...
These filters correct power factor, eliminate or reduce penalties charged by the utility, increase load capacity, and regulate voltage.

Power Factor India Office buildings have undergone a significant modernization during the last years Large quantities of computer equipment (personal computer, printers, network servers) have been incorporated. All these equipment generate elevated levels of harmonics, which cause important problems in the electrical installation and the computer equipment itself. The triple harmonics (3rd, 9th etc.) are especially harmful as these sum in the neutral conductor and generate a high neutral current causing serious failures and damages in the installation. NAAC has developed a series of electromagnetic filters for elimination of harmonics named 'H.F. System' (Harmonic Filter system). These equipments are based on the cancellation and compensation of magnetic fluxes. The main advantage of the Harmonic Filter System is the absence of electronic components and capacitors. The Harmonic Filter System are therefore maintenance free, have an extremely long lifetime compared with other types of more...
