Active Harmonic Filters (AHF) today is designed to calculate the amplitude and phase angle of each harmonic order up to 71st Order Harmonics. The Active Filters is a very advanced power system device that is directed to produce a current of equal amplitude but in a counter shape. This limits the response to specific harmonic orders and may require less than one cycle (<100microseconds). It is a complete solution for harmonic filtering along with the improvement in power factor correction.

Clariant Power System’s AHF is a high-speed IGBT based device that is to be connected in parallel to the plant. It works by sensing electrical behaviour and instantly corrects the same. This is achieved by using intelligent precise control technology and sophisticated signal processing. The device constantly monitors and injects the compensation current for a single load as well as the whole plant on real-time basis. Neutral Current Compensation is also possible by using 3Ph, 4Wire AHF System.

Through continuous R&D and with innovation and technological advancements; we aim to drive ourselves as a leading Power Quality Solutions Provider to every industry worldwide by examining the plant specific problem and providing them with the most effective and reliable solution.

The increased consumption of power electronics based electric loads or also termed as non-linear loads, generally distort the current & voltage waveforms causing it to be non-sinusoidal in nature at the consumer locations. These waveforms or Harmonics which are a multiple of fundamental frequency hamper the power quality and overall efficiency of electric power system.
