Power Factor

What is Power Factor?

The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load to the apparent power in the circuit, and is a dimensionless number between 0 and 1 (frequently expressed as a percentage, e.g. 0.5 pf = 50% pf). Real power is the capacity of the circuit for performing work in a particular time.

What is Power Factor Correction and how can a POWER MISER Unit benefit my home or business?

Power factor correction brings the power factor of an AC power circuit closer to 1 by supplying reactive power of opposite sign, adding capacitors or inductors which act to cancel the inductive or capacitive effects of the load, respectively.

A desired Power Factor is 1.  Many homes and building operate at or around .7 to .8 Power Factor meaning that you are drawing more energy through your meter to produce enough power to run your inductive motors in your home or business.  The POWER MISER product line addresses this issue by creating a power factor in your home or business at .95.  The result, increasing your power factor reduces the draw from the power company to run those same inductive motors in your home, saving consumption and in the end, saving you MONEY…


In the business world, bottom line profitability and efficient production are everything. Downtime and MaintenanceRepairs can be detrimental to a facility, and if it is a repeat situation, which can cost thousands of dollars causing your operating costs to go through the roof.

Correcting the Power Factor allows your electrical system to operate as it should, but use less energy to perform the same amount of work which supports the Industrial Energy Savings Initiatives and the Energy Sustainability Initiative. It also provides a nearly efficient electrical system throughout your facility, which allows your electrical equipment to run smoother and cooler, therefore, eliminating the possibility of pre-mature failure and repeat downtime and maintenance issues while reducing the electric bill.   Our products perfectly optimizes your electrical system with just one installation.

Why It Works:

Every facility has electrical waste…in the form of Line Loss, Heat, Poor Power Factor.  We focus on all of the above, optimizing each and every electrical waste option to ensure you only use what you need as far as energy. We monitor each device with each installation. Each and every facility or building gets a custom engineered system to achieve the MAXIMUM RESULTS for the investment.
