What is Harmonic Distortion?
Harmonic distortions are common voltage and current variations due to changes in frequencies within the electrical distribution systems. In particular, there are deviations from the typical sinusoidal variations in voltages or currents.
Harmonic distortions may result in:

Extra Power Consumption
Extra operation cost is required to maintain constant and sufficient system output.

Solution:
Active Harmonic Filter
Active filters are very easy to switch the harmonics of the power line without depending on the reactive power of the basic frequency. These filters use an outstanding technique wherever the filter utilizes self-generated harmonic components & infuses this into the power line to cancel the unnecessary harmonics.

Hoteam HTQF active power filter (APF)
Hoteam HTQF active power filter (APF) provides a truly effective harmonic solution with the advanced active harmonic compensation technology. HTQF APF behaves like a harmonic current generator. It measures the harmonic current generated by nonlinear loads and cancels the harmonics by generating an pposite phase harmonic current with the same amplitude and injecting it to the line, making source current sinusoidal.
