What is a Power Factor?

Power Factor Correction Explained & How To Lower Power Bill using it:

You may have heard the term “power factor” before in relation to your energy bill or in some other way. But what is a power factor? Well, I will try to give a brief and basic understanding of this principle without getting very technical.

To begin, you first need to understand that there are types of electrical appliances (particularly ones that use “inductive motors”) which are not totally efficient, in that they consume more power than they actually put to use. Here is a basic example just to illustrate the point:

Let’s say you are trying to pull a heavy box along the ground with a rope. If the box weighs 100 lbs, then you need to exert at least 100 lbs of force to pull it in the direction you want it to go. Now, imagine you aren’t using a rope, but a heavy chain that weighs 20 lbs all on its own. Then you would need to exert 120 lbs of force to move the box. But in reality, the box itself only took 100 lbs of force to move. Switching to a lighter rope would make your work more efficient.

Now, you have 3 different values in the above example with the chain: 100 lbs of force to move the box itself, 20 lbs of force to move the chain, and 120 being the total amount of force needed to get the job done (box 100 + chain 20 = total force 120). You could now measure your efficiency. 100 lbs of work done (box moved) compared to 120 lbs of effort to do the work. This could be expressed as 100/120. The ratio of actual effort used for work as compared to the total effort. This shows you are operating at about 83% efficiency (100 ÷ 120 = .83 or 83%).

This is basically what power factor is.

If you have a motor in your home (like in a central A/C), it needs electricity. That electricity has to travel from your electric meter, through your home’s wiring, over into the motor. Power is lost on that trip (electricity encounters resistance in the wire and some power is lost). So if a motor requires, let’s just say, 10 units of electricity to operate, your power company can’t supply you with just 10 units, as some of that power will be lost as it travels through the wiring on its way to the motor. Let’s say that loss is 2 units. You need to be supplied with 10 + 2 = 12 units of power to run a motor that only needs 10. So you could show the motor’s efficiency like so: 10/12 or 83% efficiency.

An electrical appliance that operates at 100% efficiency has a power factor of 1.0. An appliance that has 80% efficiency has a power factor of 0.8. So the lower the power factor, the less efficient. A power factor of 0.5 would be terrible. A power factor of 1.0 is perfect.

Now what does that have to do with you?

Well, you are billed on how much electricity your home is using in total. That means that you are paying for the electricity that is lost on its way from your meter to the appliance, as well as what the appliance itself is really using. There is a way to correct this.

The Electric Saver 1200™ is designed to correct this problem by collecting this wasted electricity (usually wasted in the form of heat) and feeding it back into your appliances. This corrects the power factor, thus lowering the demand from your power company and giving you a lower monthly electric bill. It can also protect against power surges and even extend the life of your appliances.

We manufacture all units in the U.S.A. and are listed with UL and CuL to ensure a safe and quality product.
