ARTECHE PQ capacitors 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-Fixed (non-automatic) Capacitor Banks 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. If non linear loads are present a harmonic analysis is strongly advised to eliminate the possibility of harmonic resonance.
Type CFB Power Factor Capacitor Systems
Arteche offers a fixed amount of kVARs. They can be supplied with or without fuses or with circuit breakers. For applications where harmonic producing loads share the same power source, use "detuned" capacitor banks to reduce the flow of harmonic currents into the capacitor. And to prevent harmonic resonance.
Type FFB Detuned Fixed Capacitor Systems
Arteche offers "Detuned" fixed capacitors which include a harmonic blocking reactor to prevent damaging harmonic currents in the capacitor.
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.
