Power Factor Correction Technologies

Indicated for systems with high, continuous inductive load, for power savings and extended motor life.

Overview

"Most power factor units draw energy continuously, making up for savings unless the home has an unusually large inductive load, e.g. pool pump, old refrigerator or AC. Newer appliances have power factor correction built in. Most homes will not save money by the time the unit ROI and continuous energy draw are factored in." -- Sterling D. Allan (Oct. 2, 2007)

"It is important to realize that billed energy is a function of amps x watts x power factor. So when talking about power factor increasing and amps dropping, be sure that the final tally is better than the original, by enough to make purchase of the unit worth while." -- Sterling D. Allan (Nov. 13, 2007)

Practicality / Considerations

My experience with Power Factor Correction unit on my home - consumed more energy because of low usage time; unit itself continually draws energy.
Installing a Unit on My Home - was very easy (results were not as expected, though, and unit was removed about 1.5 months later).

ADVISORY: With any technology, you take a high risk to invest significant time or money unless (1) independent testing has thoroughly corroborated the technology, (2) the group involved has intellectual rights to the technology, and (3) the group has the ability to make a success of the endeavor.

All truth passes through three stages:
   First, it is ridiculed;
   Second, it is violently opposed; and
   Third, it is accepted as self-evident.

-- Arthur Schopenhauer (1788-1860)

"When you're one step ahead
of the crowd you're a genius.
When you're two steps ahead,
you're a crackpot."

-- Rabbi Shlomo Riskin, (Feb. 1998)
