We see from your search that you're looking for information on the term "Harmonic Filters",
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 Harmonics considerations for panel builders from
REO (UK), which we summarised at the time by saying "Should mains harmonic distortion be a major concern for panel builders?".
Several months prior to that,
we featured the news release Disk describes AC drives in HVAC from
Danfoss Motion Controls: "HVAC Planet is billed as the most comprehensive guide currently available on AC drive control and applications within the HVAC sector".
In July 2005, we covered the news from Mitsubishi Electric Automation Systems
concerning its Active harmonic filters
- take a look at Active harmonic filters offer plantwide protection
which says: "Until recently, the solution to power harmonics caused by variable speed drives and the like has been to fit a small filter to each drive, but now there is an alternative, writes Guy Kennett".
Take a look also at the news release from Silverteam, Matrix filters promise harmonic solutions,
as well as Drives head to Merseyside from Schneider Electric,
and Harmonic filters optimise drive performance from Danfoss Drives.
