APQ LLC Type C Solutions improve power factor, reduce circuit conductor and transformer losses, and can eliminate power factor charges on your electric bills. By reducing the reactive power demand, they can make additional capacity available from existing transformers.

APPLICATION - Environments with minimal electronic loading (i.e. variable frequency drives, ups systems, computers, etc) can implement Power Factor Correction Solutions without the need to compensate for harmonic frequencies. Type C solutions are designed solely for the purpose of providing the proper amount of kVARs at the appropriate times to meet predetermined system goals. Fixed solutions are typically used to improve the power factor of individual inductive loads (motors) or a group of loads that has a relatively constant demand for reactive power (kVAR). Maximum benefit is achieved when installed as close as possible to the load. Automatic Power Factor Capacitor Systems automatically adjust the connected capacitor kVAR to the system needs based on commands from the internal electronic power factor controller.

  • Type CFB Fixed Power Factor Capacitor Systems

    APQ CFB products offer a fixed amount of kVARs. They can be supplied with or without fuses or with circuit breakers.

  • Type CAB Automatic Power Factor Capacitor Systems

    APQ CAB products offer variable amounts of kVAR dependant upon the requirements of the load. Standard product options include fuses, blown fuse indication, and circuit breakers.

Power Factor Reduced by Inductive Loads
Inductive loads can demand large amounts of reactive power and reduce overall facility power factor. The full load power factor of individual motors can range from 0.60 to 0.93 and drops as the load is reduced. Since many motors are de-rated or operate well below full load conditions, typical power factors may be much lower than stated on the motor nameplate. When capacitors are added to motors, the capacitor supplies the reactive power needs of the motor, thus improving power factor at this point and all points upstream from it. Both the facility and the electric utility benefit when fixed capacitors are applied right at the motor or other inductive load.
