We see from your search that you're looking for information on the term "Harmonic Filter",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release The true price of power supply harmonics from
Block UK, which we summarised at the time by saying "Bob Liddle explains how to reduce the effects of harmonic distortion on power supply lines, thereby eliminating equipment failures and cutting production downtime, repair and replacement
costs".
Several months prior to that,
we featured the news release Filters clean up nonlinear loads from
Block UK: "Harmonic filter modules reduce distortion, RMS and peak currents to acceptable levels".
In April 2006, we covered the news from Block UK
concerning its HFM
- take a look at Modules reduce harmonic distortion
which says: "Harmonic filter modules designed to reduce harmonic distortion, RMS and peak currents to acceptable levels".
Take a look also at the news release from MGE UPS Systems, Extranet site aids UPS specification,
as well as Harmonic filter improves true power factor from TCI,
and Active harmonic filters offer plantwide protection from Mitsubishi Electric Automation Systems.
