ABB's new portfolio comprises five solutions: PQflexC -- variable reactive power controller; PQdynaC - ultra-fast reactive power and unbalance controller; PQactiF - active harmonic filter
; and PQStorI - battery storage inverter with power quality functions.
The next option is to use a series harmonic filter
. It provides more effective compensation than a line choke, significantly reducing total harmonic distortion (THD).
By changing the characterization of the 2nd harmonic filter
, the harmonic values can be reduced but this may cause the interharmonics between 50 Hz-100 Hz to rise.

branch parameters," IEEE Transactions on Power Delivery, vol.
The standard motor drive analyzer software provides either full-spectrum (no harmonic filter
applied) or fundamental-only harmonic filters
Schaefer's PB-W (wall-mount) Series of three- and four-wire active (3x200 to 3x480 VAC) harmonic filter
modular systems are designed to meet IEEE-519.
has introduced its PB-W (Wall-Mount) Series of three-wire and four-wire active (3x200VAC to 3x480VAC) harmonic filter
modular systems that are designed to meet IEEE-519.
The scope of supply for the new order includes two VSD systems, all of the ancillaries such as cooling systems, control systems, transformers and harmonic filter
A 100 Amp Active Harmonic filter
may be installed in PDB2 of Plant III supplied by TX1.The Plant III has got 30 Ring frames, each ring frame having VFD (Variable Frequency Drive) of 50 KW rating.
Implementation of the harmonic filter
is a popular method for cleaning up the spurious signals emitted by transmitters.
