The benefits of power factor correction including;
1. PFC power supply save energy.
2. Increased system capacity
3. Improved voltage
Low power factor means poor electrical efficiency. The lower the power factor, the higher the apparent power drawn from the distribution network. When low power factor is not corrected, the utility must provide the nonworking reactive power in addition to the working active power. This results in the use of larger generators, transformers, bus bars, wires, and other distribution system devices that otherwise would not be necessary. Electronic equipment with PFC could promote it-self energy utilization to help cut consumer bill in percentage , also PFC is a environment friendly technology, reducing the harmonics that creat electrical polluation to benefits the society as a whole.
