Explanation of Power Factor - L M Photonics Ltd. sells power factor calculator.

Companies

NAAC Energy Controls - Offers the most advanced and best in World Power Quality Solutions with thrust in the key areas of energy audit India, energy saving and Power Quality Management India.

sEnergy Solution introducing motor, lighting, and thermal-control efficiency retrofit solutions - Motor control unit only pulls as much energy as is required to maintain torque, resulting in far lower net energy consumption and longer motor life. Enables soft start, soft stop, hard start, and other features. (PESN; Oct. 19, 2006)

Pacific KVAR Power Conditioning Units - The KVAR/KEC system reduces the amount of power drawn from the utility by eliminating otherwise lost electricity (reactive power) created by inductive loads at any given facility. The KVAR Energy Controller unit stores and releases this reactive power thus eliminating this wasted energy.

Xedia Technologies, Inc. XPower Saver - Supplies reactive power locally at the load by the use of specially designed capacitors. Improves Power Factor closer to Unity resulting in better electrical efficiency and cooler motors. There is now also a 3-phase 240v device called the XPS.

USES® Power Enhancement Systems - Power conditioning hardware for industry, to reduce electrical consumption, protect equipment and save money.

Powergy Clean Power Systems - power conditioning devices for sale for residential, small business, commercial applications; increases efficiency of power usage and longevity of appliances.

The Power-Save 1200™ - "The Power-Save 1200™ energy saver is responsible for thousands of Americans saving millions of combined dollars on their utility bills! The Power-Save 1200™ saves families as much as 25% on their electric bill every month without sacrificing normal energy consumption and the comforts it provides."

Electrotek - Specialists in the design and manufacture of power factor correction equipment and harmonic filters.

Mini Sun Power - This Korean company has been manufacturing and distributing electricity saving devices since 1998.

Compact Fluorescent >
Are U.S. CFL's Designed to Make Us Pay More on Our Power Bills? - In Europe, a small capacitor is added to Compact Fluorescent Lamps for power conditioning and additional savings on the utility bills. Similar savings can be realized on AC motors. Why are these inexpensive modifications omitted from U.S. CFLs and many residential motors? (PESWiki; Aug 25, 2008)

Most modern home appliances that have inductive loads, such as air conditioners and refrigerators, come with power factor conditioning built in. Therefore, purchasing a power factor correction unit for a home is not really indicated. In fact, because the unit draws continuous power, even when no power is being called from the home, the unit can end up resulting in more power used, not less.

Power factor correction is usually used in industrial settings, where large inductive load exists; in which case tremendous power savings are realized, as well as greater longevity of the appliances.

The only time power factor correction is really helpful in a home power setting, is if there is an unusually high inductive load, such as from a pool pump, or a koi pond pump -- unless the unit does not draw current during "idle" mode when no inductive load is present.

Otherwise, buying power conditioning units for home use is most likely to be a waste of money.

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.

My experience with Power Factor Correction unit on my home - consumed more energy because of low usage time; unit itself continually draws energy.
