How KVAR Energy Controllers work?
The KVAR Energy Controller optimizes the Power Factor by reducing the amount of Reactive Power (kVAR) that the load draws from the utility company.
KVAR Energy Controllers store the Reactive Power (kVAR) needed for the creation of the electromagnetic field (EMF) within the inductive load.
As the motor operates, this reactive power is "pushed" and "pulled" to and from the KVAR unit by the motor. Thus, through power factor optimization, the quantity of reactive power required to be purchased from the utility company is greatly reduced, perhaps even eliminated.
Real Power is measured in kilowatts (kW). It does the "work" for the system--providing the motion, light, etc.
Reactive Power is measured in kilovolt-amperes-reactive (kVAR). It doesn't do useful "work.” it simply sustains the electromagnetic field needed for motors
Apparent Power is what the utility company charges you.
Real Power and Reactive Power together make up Apparent Power. Apparent Power is measured in kilovolt-amperes (kVA).
Induction loads, anything with a motor, require kVAR to establish EMF (electromagnetic field) around the motor induction windings. The EMF provides the torque necessary to turn the motor shaft. Without kVAR (reactive power), the motor would not turn. Only after you have established the EMF around the motor induction windings will the motor shaft then turn. The power that is used to turn the shaft on a motor which turns pump impellers or fan blades etc… is called the real power or kW. By implementing the KVAR Energy Controller to individual loads you are providing the necessary kVAR for that load and therefore the power you buy from your utility company is mostly Real Power or kW as opposed to a combination of both Real power and Reactive Power – so your Reactive Power is reduced therefore your energy consumption is reduced!
