Any time an inductive load such as fans, compressors, ballasts or anything containing a motor is connected to a power grid the current will lag the voltage. The phase angle of this lag (Cos q) is referred to as Power Factor. Electrical companies allow a 90% to 95% PF. The electrical companies penalize the consumer if the consumption rate is outside of this range.

Voltage and current change direction 60 times per second. If the voltage and the current change directions at the same time and in the same direction, the Power Factor is said to be unity. If the current lags the voltage, the PF becomes less than unity and some of the current will be effectively â??wastedâ?ť. The innovative circuitry of the Equalizer will â??re-alignâ?ť the PF, resulting in better power efficiency for the consumer.

Electrical motors in the home consume inductive power, which is a common cause leading to voltage and current misalignment. When switched on, they draw Apparent Power (kVA) from the mains due to lagging current. kVA is comprised of Active Power (kW), the power actually being consumed, as well as Reactive Power (kVAr), the power feeding the inductive portion of the load.

Reactive Power (kVAr) is of no benefit to the user, but does cost the consumer money. The less kVAr used the greater the savings, with no reduced consumption. Real Power and Apparent Power are said to be at unity, at 1.0 PF, if they share the same plane. All electrical energy is then going towards real work.
