25. A REVIEW ON SYSTEM FOR MINIMIZING BILLING PENALTIES BASED ON POWER FACTOR DUE TO APFC UNIT

In the industrial division, number of motoring loads is running continuously. These motoring loads generate inductive load. Power consumption is increasing day by day at a very high rate. So, because of this inductive receptive force, the force factor gets diminished. The power organization has indicated certain cutoff points, if the force factor gets beneath these predefined limits punishment will be forced to the modern customers. To defeat inductive reactance remuneration is accomplished by the utilization of force capacitors. APFC gadget peruses the force factor from line voltage and current by deciding the delay in arrival of the current signal with respect to voltage signal with high accuracy using internal timer. These values are calibrated as phase a ngle and corresponding power factor. Then the calculation for the requirement of compensation takes place in the motherboard and accordingly different capacitor banks are switched on.
