Power Factor Correction Devices
Helping You Use Electricity More Efficiently
Power factor measures how efficiently a building uses electricity supplied by a utility company. A high power factor ensures that your electric equipment run more efficiently by reducing the amount of energy needed. Many businesses in the U.S. have a power factor between 0.7 and 0.9, indicating that 10-30% or more of their electricity is being wasted.
Power factor is defined as the ratio of real (working or kW) power to apparent (total or kVA) power. For example, we know that the shortest distance between two points is a straight line. However, because our roads don’t go exactly in a straight line, we end up driving further to get to the same place. The same is true for electricity. A motor may need 100 kilowatts of power to operate, but it may be drawing 115 kilowatts instead. Inductive electrical loads increase the amount of apparent (total) power causing the power factor to decrease. Power factor correction devices like our Electric Saver Power Box create a condition where the power supply is more constant, more efficiently supplying varying loads of power. The result is a power factor increase and less wasted energy.

Power Factor Correction with an Electric Saver Smart Box
Your electrical bill is likely to shrink. Additionally, many utility companies charge a fee if your power factor is too low. Correcting your power factor will help you avoid this fee.
Uncorrected power factor can cause voltage drops and/or power losses in the electrical distribution system. This can result in overheating and premature failure of motors and other inductive equipment. Proper power factor will allow your inductive equipment to operate more efficiently and last longer.
Additional Electric Saver Smart Box benefits include:
