ACTIVE HARMONIC FILTER


  With the increasing use of non-linear loads, such as inverters, VSDs, LED lamps, rectifiers and other rectifiers (DC/AC converters) it causes the appearance of harmonic frequencies in the power grid. The harmonic frequency is the electrical frequency which is a multiple of the fundamental frequency (fundamental = 50 Hz). So in the power grid, the frequency from the source is only 50Hz. Due to the use of this equipment, frequencies of 100, 150, 200, 250, 300, 350Hz appear, and so on.


  The emergence of these harmonic frequencies can cause disturbances in some equipment, especially Capacitor Banks and control relays. The capacitor bank is the component most affected by harmonics because its performance is affected by frequency. As is well known, the impedance of a capacitor is a function of frequency according to the equation:


  Xc = 1/(2*phi*f*C) --> I = V/Xc


Xc = Impedance of the capacitor (Capacitive reactance) (Ohm)

f = frequency

I = Capacitor Current (Ampere)

V = Voltage (Volts)


The easy explanation is as follows:


If the value of f changes, then the value of Xc will change. The greater the value of f, the smaller the value of Xc will be.


The smaller the Xc value, the greater the I value.


An example of the phenomenon of the harmful effects of harmonics which is currently frequently occurring is a building fire caused by an exploding capacitor bank panel. And often this incident occurs when the load is small, namely at night.


Why is this happening?


At night, the majority of the load that is lit is lighting, and generally the lights are now LED lights, which are sources of harmonics (3rd harmonic). As a result, the percentage of harmonics (THD) becomes large and will greatly affect the capacitor.

During the day, many other (non-harmonic) loads are on, so that the percentage of harmonic current (THD) to the total current is small.


To overcome this problem, an Active Harmonic Filter (AHF) is needed to eliminate harmonic currents. The working principle of AHF is to inject a current that is opposite to the harmonic current so that the resultant harmonic current is 0 or becomes smaller.​


The size of the AHF is determined by the magnitude of the harmonic current, not the total load current.

What is generally a mistake is that the size of the AHF is determined from the total current so that the need for AHF becomes very large and the investment required becomes very large.


Integra Pure Sine is an Active Harmonic Filter as our solution to overcome these harmonic problems. We also provide services for measuring the actual needs of the required AHF. The Integra Pure Sine AHF range is for 35A, 60A, 100A and 150A capacities.
