What is power factor correction?

Power factor correction improves power quality and availability by helping to optimize power consumption, and to compensate for voltage drops and other transient supply cuts that negatively impact process functioning.

Power factor correction increases the power factor of a load, improving efficiency for the distribution system. Linear loads with low power factor can be corrected with a passive network of capacitors or inductors. Non-linear loads require active or passive power factor correction to counteract the distortion and raise the power factor.

Power factor correction can be undertaken at a central substation, spread out over a distribution system, or built into power-consuming equipment.

Power factor correction modules, primarily, include a prewired sub-assembly constructed and designed that is utilised for mounting fixtures in power factor correction cubicles that may be present as a stand alone or within the Main Low Voltage Switchboard.

Power factor correction modules usually include two categories, such as single modules (which has one contactor) and double modules (which has 2 contactors). At Schneider Electric, you can explore different types of power factor correction modules depending on the different harmonic pollution.

Power factor correction modules consist of a prewired sub-assembly constructed and designed for mounting fixtures in power factor correction cubicles, which are either stand alone or inside the Main Low Voltage Switchboard. Power factor correction modules can be single modules (with one contactor) and double modules (with 2 contactors). Schneider Electric offers different types of power factor correction modules as per the different harmonic pollution.
