ACTIVE HARMONIC FILTERS (TYPE AHF) 200-690 VOLTS 50/60HZ
APPLICATION: Active filters are typically used wherever the non-linear load represents over 50% of the total load such as water, wastewater and deep tunnel applications. They are also very useful in general industrial applications where space is at a premium, where shunt filter connection is preferred over a series connection, and where multiple loads require filtering.
Type AHF Active Filters
Arteche Type AHF Active Filters utilize the latest IGBT power electronics technology to dynamically cancel harmonic current from the 3rd to 51st harmonic. Through the injection of inverse relationship compensating current, harmonics are significantly reduced and the sine wave is restored. IGBT technology enables our filter to respond to rapid load fluctuations and changing harmonic conditions. Our active filters achieve harmonic current distortion levels as low as 5% THD-i and comply with IEEE-519 and other international power quality standards.
