We see from your search that you're looking for information on the term "Power Factor Correction",
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 Cashing in on variable speed savings from
Energywize, which we summarised at the time by saying "Energywise is a new company launched with a mission to save energy using variable speed drives".
Earlier in the week,
we featured the news release Safety first in electrical testing from
Seaward Electronic: "Portable tester is the first of its type for the safe discharge of stored energy in large capacitors and electrically charged equipment".
In October 2007, we covered the news from Seaward Electronic
concerning its SD300 discharge device
- take a look at Device safely discharges electrical equipment
which says: "The portable SD300 is a self-contained safe discharge device that has been designed to protect the operator or test engineer from danger and the equipment under test from potential damage".
Take a look also at the news release from B and R Industrial Automation Corp, Power supply modules optimise current consumption,
as well as Switchgear meets industrial demands from Eaton Corp,
and GRP enclosures survive demanding environments from Eaton Corp.
