We see from your search that you're looking for information on the term "Power Quality Problems",
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 Compensator improves network power quality from
ABB Power Technologies, which we summarised at the time by saying "The Dynacomp acts as an ultra-rapid and transient-free capacitor bank with the reactive power step switching carried out by thyristor modules".
Several months prior to that,
we featured the news release Power quality problems explained from
Copper Development Association: "Seminars are aimed at businesses wishing to address the serious problems of downtime and losses caused by failures due to poor power quality".
In March 2007, we covered the news from Frost and Sullivan
- take a look at UPS market has potential for growth
which says: "Although slow technological development and lack of end-user perception pose major challenges, industrial UPS markets across the world offer good potential for growth".
Take a look also at the news release from Fluke (UK), DVD explains power quality optimisation,
as well as Line reactors and filters run up to 1200A from REO (UK),
and Current clamps complement three-phase analysers from Fluke (UK).
