Power Factor Correction

What is Power Factor?

Power Factor (PF) is a measure of how efficiently power is used. The more efficiently you consume your energy, the higher the PF and the lower your costs.

iuImagine a horse pulling a train car down a straight track. The most efficient way to pull the train car is when the tow rope is in the same direction as the tracks. The further the horse moves to the side of the track direction (i.e. increases the rope angle) the harder he has to pull the train to get it to move the same distance. The angle between the track and pull direction is a measure of inefficiency also known as power factor and some utilities charge a penalty for poor power factor. The goal is to get as close to 1 as possible, a Power Factor >0.95 is excellent and usually eliminates those unnecessary penalties.

The more inefficient systems operate; the lower your PF. Low PF results in higher penalties from the Utility. Typical culprits that cause low PF are air conditioners, presses, manufacturing machinery, or anything with a motor. Fortunately, there are proven ways to correct low PF that offer excellent returns with no impact to your equipment or daily operations. Correcting your PF not only reduces your costs but could also extend the life of your equipment and slightly lower your usage, all because you use power more efficiently.

What to do?

Sometimes PF is listed on your Utility/Supplier bill, if not, QuotEnergy can do the calculations for you to define the penalty you pay each month, just let us know and we are happy to provide a free evaluation.
